Press brake or break press is a equipments used for bending sheets of metals, or other materials. Prior to using a metal plate or a sheet it has to be shaped or formed. To do this a machine or a press brake is required.
There are many kinds of devices like mechanical, pneumatic, hydraulic and servo-electric. These are available in different sizes and specifications and are used in repairing workshops, auto service stations, industries etc.
Mechanical press brake
In this an electric motor supplies energy to a flywheel which powers a crank mechanism to move the ram vertically. These devices are fast and accurate. This is the conventional version of it.
Hydraulic press brakes
This is operated with the help of two hydraulic cylinders. It has a C-frame which moves the upper beam. It is a very agile punching machine as it can punch as well as foam in both upward and downward direction. This is a mechanized version.
Ways in which Press brakes are employed for sheet metal bending:
They are very adaptable kind of machines. It is the perfect press for forming metal as the force is applied in a longitudinal region. Some of the materials that are used for forming on a press brakes are alloy steel, stainless steel, low carbon steel, aluminum alloys, copper alloys etc.
It is extensively employed for multiple purposes in the industries. The metal is subjected to immense stress and shaped using dies. The metal to be shaped is clamped between a punch and a die and pressure is applied. The metal takes the shape of the die every time the force is applied with the punch. The inside angle of the bend is formed with the punch and the outside angle with the die.
Repeated operations using suitable dies help to cast the metal into the desired shape. Different methods are used to cast the metal like U –die bends, V-bending, bottoming, double die bending etc. A strong firm table forms the base of the machine and the beam on top moves up and down to punch the metal.
Metal can be cut to required shape and size using press breaks. Mechanical press breaks are a good choice for small scale manufacturing units as the job done is very accurate and facilitates easy cutting work. If bulk production in short period of time is needed then hydraulic press brakes is a better alternative. Since it works by hydraulic power system, the machine can be set according to the production requirement. These multi-purpose press brakes can be modified for varied operations.
Select a press brake according to your requirement, type of work, frequency of work and the size of metal sheets to be formed. Mechanical and hydraulic are generally used to form the metal. In order to perform metal bending jobs efficiently, it is important to select the right.
It is a kind of bending machine used for bending sheet metal into a predetermined shape. The bending depends upon the shape of the punch and the die. These are being widely used in metallurgy, aircraft and ship building, production of container and many other metal products.
Working principle of Press Brake
The metal sheet to be bended is placed between the punch and the die. The punch and die are placed in such a way that they are aligned in the same vertical axis and the shape of the punch matches that of the die. The metal sheet is clamped at both ends to prevent it from slipping during the bending process. After fixing the metal sheet, pressure is exerted on the punch which bends the metal sheet or plate against the die. The force applied is measured in tons and the capacity of a machine is measured in terms of tonnage. Depending on the means of application of pressure, they are classified as
Mechanical press brake
Hydraulic press brake
Pneumatic press brake
Press Brake set up
It set up refers to the work carried out by the operator to change the settings of the device according to the job. Every part will not be of the same size and shape. When a new part is to be pressed, some changes must be made in the device to get the shape of the metal sheet or plate as per the design. This set up procedure must be done very carefully because it directly affects the quality of the product. The operator must not take much time in setting up the machine as this may affect the production.
Key to set up Mechanical Press Brake
The key points in setting up it are listed below
· The operator must go through the drawing completely and know the type of material, the dimensions, blank size and the angle required.
· The type of tool should be selected depending upon the dimensions (internal radius in particular). For example, if the inside radius is less than the thickness of the material, bottom tooling can be used.
· The pressure or force required for the particular job must be determined.
· The position of the tool on the bed is selected based upon the tonnage. If maximum tonnage of the machine is to be used, then the tool must be positioned at the centre. If it is less, then the position of the tool can be offset.
·The selected tool must be installed at the determined position. The tool installation is the most time consuming procedure.
·While installing the tool, a safety tag must be used while placing the punch over the die.
·The die and punch must be aligned correctly and the distance between them must be set to get the exact slide length.
·The pressure or force to be exerted must be set by trial and error method to get the exact pressure required for the job.
·A test bend must be made on waste material to check the settings. If the settings are correct, the production can be started immediately.
Key to set up Hydraulic Press Brake
It is similar to that of the mechanical regarding the selection and position of tooling. Some additional points to be taken into consideration while setting up it are listed below
· The hydraulic oil must be clean and the level of the reservoir in the oil must be checked.
·The tool which is selected must be installed as per the manufacturer’s instruction.
·The distance piece must be set to compensate for the difference in penetration between punch and die.
·The slide length of the punch should be set using the controls.
·A test bend is carried out and if not satisfactory necessary changes must be made in the device.
·Most of the hydraulic devices are electronic controlled and so the operator must be familiar with the controls used for the set up of the machine.
Note: Even if the set up is perfect, the production won’t be efficient if the tool is worn out. Worn out tool must be sent to the manufacturer for re-conditioning.
Industrial Press brake are used in many industries and they come in various sizes and types for specific jobs. With the development of automation engineering, CNC Brake press have been developed which are computer controlled and the set up of the equipment can be done in a short period of time. The accuracy of the bend depends upon the set up of the equipment; so much care must be taken while setting up the device. Even if it takes a little longer to set up the equipment, the production should not be started until the operator is confident about the set up of the machine.

It is important equipment for the industries having jobs related to the metal shaping or bending. Two types are popular among metal fabricators – the manually operated press brakes and the press brakes which operate on the hydraulic power. The sheet metal bending whose action is sourced from hydraulic power is commonly referred as a hydraulic press brake.
It uses the power of the hydraulic motor to apply force on to the metal so that it is compressed onto the die forming the shape of the die. It is shape of the die that determines the shape acquired with the metal bending process. These can carry out an automated bending process and hence are the choice of many manufacturers looking for faster and efficient bending devices for cost effective bending processes. The precision of bending acquired with it is also excellent. Moreover as they are available in user-friendly formats, it is really easy to form metals into the required shapes using these hydraulic machines.
The main advantage of using it for metal bending operation is the flexibility it offers for the bending operations. With this, one can cast customized shapes out of different kinds of metals. Therefore employing it for bending operation will give much efficiency in work than an ordinary bending machine which can only bend or curve the metal but cannot cast out the required shape out of it.
The bending mechanism of it is a stamping process where the metal sheet is stamped into the mould or dies for casting it into the required shape. Initially as an input, sheet metal is fed into the device which gets aligned on to the die. Then as the force is applied on to this metal with lowered press or boom the metal is stamped into the mold. Hence this casts the sheet metal as per the shape of die. Therefore it is no wrong to say that die is a crucial component of a hydraulic brake because it’s the shape of die that will determine the shape of the object formed with the sheet metal. With continuous, repetitive sheet metal pressing using the properly selected dies one can cast customized shapes easily using today’s hydraulic machines. It is possible to cast almost any shape out of sheet metal using the latest devices that come with several desired features that provide for easy and customized shaping.
For accuracy in shaping process, these are designed for vibration free operation. It can save lot of production costs for the manufacturers as they do not require manual force for operation which is usually the requirement for manual bending equipments.
A press brake is primarily used for accurately bending various types of metal sheets and plates. Some frequently asked questions are as follows:
Q. What is camber?
A. Camber is actually a small piece of cap which is placed on the ram or bed to permit deflection. This is due to the fact that, any material which is bent on a it will encounter resistance. As a result this resistance will deflect the bed as well as the ram.
Q. Is it necessary to fasten the machine to the floor?
A. Definitely, the press brake must be first leveled and then properly fastened to the floor. Otherwise 25 percent of the energy of your press brake will be wasted, due to loss of torque.
Q. How much tonnage is required for a specific task?
A. Please refer the chart on the press brake which displays the amount of tonnage needed for a specific kind of metal. For example, you can press a 0.25 inch steel plate at 15.4 tons per foot. Further, in case you are using a 0.125 inch sheet, it can be pressed at 7.7 tons per foot.
Q. Explain tensile strength and yield strength for a press brake?
A. The term tensile strength is used when you are referring to pressing a metal piece. This includes applying lots of force at a particular place on the metal piece to accomplish the task. Whereas yield strength refers to applying relatively less force in order to roll a metal piece. Hence in order to press stainless steel or any other metal, you will require a larger press brake as the tensile strength is more than 80000. On the other hand, for rolling stainless steel, you may use a smaller capacity press brake. For example, a 304 stainless steel work piece actually has a tensile strength of 95000; while the yield strength is just 35000.
Q. Why is it essential to designate the various materials?
A. Material designation is important as well as mandatory, since it provides us the detailed information of a particular metal; including the tensile strength and yield strength. Moreover, it is also necessary to ensure that you have the complete designation of a metal. For instance, A516 is incomplete and not sufficient. You must also include the grade. Hence A516-55 means that the tensile strength is 55-75000 and the minimum yield strength is 30,000. And A516-70 refers to tensile strength of 70-90,000; and minimum yield strength of 38000.
Q. What is the maximum capacity of a press brake?
A. The maximum capacity is basically, the rated tonnage of the tools. Hence you should find out the relevant tonnage per foot, and then just multiply the tonnage by the number of feet you require. However, while using short pieces of metal, it is always advisable to slightly move the work piece in order to prevent the bed from getting damaged.
Hence these FAQs on press brake will help potential and existing users to solve their queries.

A number of machines are used in the process of fabrication of sheet metal parts. Fabrication is the process of collective operations which are used to give a shape to the metal sheet. This involves a number of equipments like metal shears, laser cutting, press brakes, rollers, welding machines etc.
Press brake, also called break press, is a machine that is used to bend the metal sheets and plates. A considerable amount of force is applied using mechanical or hydraulic processes or both. In order to get perfect bends free from any defect, care must be taken to use proper methods. The commonly used metals for fabrication are carbon steel, stainless steel, and aluminum.
Types of Press Breaks
Press brakes are available in two categories:
Mechanical press brakes – A mechanical press is faster and more accurate as compared to other.
Hydraulic press brakes – These help to create goods of superior quality which use less power and are dependable. These are safe to use but are more expensive. For accurate bending of sheet metal and metal plates it is widely used in many industries.
The process of applying force on the metal to change its shape without cutting it is called metal forming. The sheets are bent or stretched into an array of complex shapes.
In the process of sheet metal fabrication, first the basic flat shape of the metal sheet is attained, the metal is then sent to machines to make the bends. The metal sheet is placed between a punch and a die. This process is called forming. According to the specifications on the prints, dies in a range of shapes and radius are used to make one or a number of bends to form the metal.
Applications of Press Breaks
In order to increase the inflexibility of a metal, and to shape the pieces of metal in shapes of one’s choice and design the metal is bent using it. Bending is a flexible process in precision sheet metal fabrication and it permits the formation of different shapes by using hammering and press brakes.To find the correct bend allowance for the compressionand stretching of the material, intricate mathematical formulas are required.
Press brake forming method is used for different functions like metal framing, metal housing for a definite part, brackets for tools and machines etc. It is also used for punching, bending, piercing etc. of the metal sheet.
Metal fabrication is done for a large array of industries and applications. Car parts, aircraft components, boat propellers, holding tanks, shark cages, weapons, etc. are fabricated from metal. Different tools are used for different purpose during fabrication of metal, so a technician can shape the metal according to his desire.
So, without the press brake machinery the work of a fabricator would be very difficult. To give shape to the metal sheet before it is cut, It play a very significant role. These are used in every metal industry and for almost every metal fabrication be it a piece of art or a part of a car.
Press Brake, Slotting Machine – It used for Bending and Cutting Metals
Cutting and bending are the two primary functions performed on metals for casting the desired shape or dimensions. Therefore when it comes to metal working, the two most popular categories used in workshops are metal cutting and metal bending machines. Much of the metal processing tasks in workshops are usually carried using these equipment.
The popular form of metal bending machines used in workshop is a press brake. A press brake is a popular workshop tool installed with punches and dies to form bends on the metals. Combining a series of repetitive bending operations metals can be bent to desired shape. A press brake is usually classified on basis of factors like force and working length. There are four popular forms of press brakes widely employed in workshops and industries called mechanical, pneumatic, hydraulic, and servo-electric brakes. A functioning of a mechanical variant of this metal bending unit is dependent on flywheel, the pneumatic model utilizes the air pressure, the hydraulic press brake from http://www.bhavyamachinetools.com/pressbrake/hydraulic.html functions by means of a pair of hydraulic cylinders where as a servo-electric brake works on servo-motor to drive a ball screw or belt drive to exert tonnage on the ram for bending metals to desired shape or dimensions as required. The shape casted using a brake is dependent on the type of die used in the device. Various kinds of dies can be installed in press brakes like v-dies, U-bend dies, goose neck dies, acute angle dies, offset dies, hemming dies seaming dies and much more to achieve desired shape from a metal work piece. With an appropriate die installed in your unit, you can cast almost any shape out of a metal work piece with varied repetitive operations.

The press brake is primarily a machine tool that is utilized for bending a metal sheet or plate, into a shape which is determined by its die set. It forms preset bends by tightly holding the workpiece between the punch and die set. Usually it has two C shaped frames on both the sides. It is firmly connected to a table at the bottom and has a moveable beam at the top. The top tool is mounted on the upper beam, whereas the bottom tool is mounted on the table. It is actually a multi purpose fabricating machine, and therefore suitable for several types of metal forming operations.
It has the capability to deliver force in a limited vertical space in order to punch or bend the metal sheet. A variety are now available in the market. However, they are mainly categorized as mechanical or hydraulic, depending on the means of applying force. In the early days, mechanical brakes were mostly used. And later on with the advancement in technology, the hydraulic press brakes were introduced in the market.
Choosing a specific type mainly depends on the material to be used, the type of operation, as well as the rate of output. This versatile press brake is utilized for various types of forming operations using different kinds of dies. The numerous applications of different kinds of press brakes are described further. Actually these are regarded as an essential part of several manufacturing industries. Hence they are commonly used in a wide range of industrial segments such as wood, metal, automobile, rubber, plastic, etc. It can be used to produce the metal plates of front, back and side panels of a computer. It is also utilized for manufacturing metal brackets, frames and cabinets.
Mechanical Press Brake
It has a flywheel that is powered by an electric motor. It also has a clutch that engages the flywheel to initiate the crank mechanism, for moving the ram in the vertical direction. This machine exerts pressure in order to form, shape, or cut a material; extract liquids, or compress solids. A mechanically driven has a fixed tonnage, and exerts more force at the bottom of its stroke as compared to the halfway point. The two major benefits of mechanical press brake are speed and accuracy.
Hydraulic Press Brake
It functions through two synchronized hydraulic cylinders on the C frames, in order to move the upper beam. This machine exerts a great force on the larger piston in a pair of hydraulically coupled cylinders; whereas a relatively smaller force is applied to the smaller piston. They use hydraulic oil or fluid pressure as a source of energy. These are easy to use and maintain. They are basically high speed, compact machines that are more precise and use less power. Moreover, this machine is highly reliable and hence much safer than the mechanical press brakes.
The objective of this article is to educate readers about different types of press brakes and their industrial applications.
A press brake is also referred to as a brake press. It is basically a powerful machine tool that is commonly used for bending sheets and plates; particularly for bending sheet metal. It forms preset bends by holding the work piece in between the suitable punch and matching die. These are normally classified as per the means of applying force. The different types available in the market include the mechanical, hydraulic, pneumatic, and servo-electric press brake.
There may be many reasons for buying and using it. Hence selecting the right one for your workshop is very important. Thus, first of all it is necessary to determine the type of work that needs to be done. Nowadays, several manufacturers provide a wide range of press brakes in different dimensions and specifications. You can select a particular model, of the required size and quality, as per your specific needs and budget.
Moreover, before selecting, it is recommended to take the advice of an expert, or a reliable supplier and reputed manufacturer; since they have in-depth knowledge and vast experience about the various types and models available in the market. There may be various reasons for purchasing a press brake such as; for starting a new workshop, for expanding your manufacturing capacity, for fulfilling a specific requirement, or just for replacing an existing press brake.
Further, it also depends whether you a need it for a short term and on a temporary basis; or for a long term and on a permanent basis. Another significant factor is your financial plan. This refers to your budget limit, and whether you are ready to purchase a costly machine. In case, you have a limited budget and temporary requirement, you can also select used or second hand one. On the other hand, if you can afford a new, it will be more effective and also last for many years. Besides, a new and good quality machine will assure better accuracy, higher efficiency, and total safety.
Moreover, another important factor is finding a renowned and trustworthy supplier. This is relatively confusing, because today there a numerous local and international companies that supply new as well as old machinery. You also need to confirm that the required model is of high quality, and is also available at the appropriate price.
Hence, you should contact a reliable supplier who has sufficient knowledge about the various types and models. And this supplier must be capable to properly guide and suggest the buyers, to select a particular type of machine that suits their specific purpose, meets their individual needs, and is within their budget limits. Moreover, it is better to select a supplier that also provides all the related spare parts and even offers services for repairing and maintaining various press brakes.
These days, various types of press brakes are available in the market, including mechanical and hydraulic. The main differences between a mechanical and a hydraulic is as follows.
Hydraulic press brakes are simple to use and versatile for punching and forming sheet metal components. Even the tooling is easy for a hydraulic press and the material handling cost is also less. Stamping can also be done using economical tools on the same hydraulic press.
Mechanical presses use expensive dies and costly components, hence hydraulic presses are better. One more advantage of using a it is that they can be set up quickly, because they do not involve many other forming functions. It also reduces secondary forming operations such as moving the components to another machine. Hence, the hydraulic press is preferred since the tooling and set up time is less as compared to the mechanical press. Moreover, a hydraulic is a highly flexible punching, forming and stamping equipment. It can even punch and form in upwards as well as downwards directions. They also help to save manufacturing time of sheet metal parts.
The hydroforming operation is not possible on a mechanical press brake, because it does not have the speed control and cannot remain on the bottom for carrying out the high pressure forming operations. The slow speed of the hydraulic helps in the hydroforming process, in comparison with the mechanical. A hydraulic press brake provides dwelling and ram speed control which is not possible in mechanical. The hydraulic presses can be programmed to control the ram speed and ram position, whereas this facility is unavailable in mechanical presses.
Further, hydraulic press have exceptional speed, stroke and force; and have therefore increased the forming capacity of sheet metal industry. They can offer full force at any stroke position and also provide flexibility in the dies. The ram stroke can be easily adjusted from minimum to maximum position. Hence, a hydraulic press can have longer strokes to include different types of dies; and can be easily set for various operations. The major benefits of these hydraulic presses include the following.
They are multi-purpose machines, and are adaptable for diverse operations; deliver better force at any point of stroke; and are capable to function at various strokes on the same machine. The ram stroke can be simply adjusted throughout the length. Also the required speeds can be set and also easily reset at any position. It is possible to program and have total control over the ram stroke and position. A variety of operations can be performed at different pressures just by adjusting the command, pressure switch settings, or pressure control valve of the machine.
Ultimately, hydraulic press brakes deliver precise and high quality products. Hence, compared to mechanical press brakes, the hydraulic are much better. Therefore a wide range of operations are now done using hydraulic presses in various industries throughout the world.
Improvement of processes in a workshop and automation doesn’t need to be an expensive affair. It needs to be a smarter choice of tool room machines required in a workshop. Various industrial applications require rigid material like wood and metal to be cut, shaped and grinded on a regular basis. These are exactly used for those processes. A workshop needs to provide properly shaped metals to the industries so that they can further manufacture the products of high quality. Proper use in a workshop enables accurate and quick output which becomes very much necessary for all the industries. Basically, there are some important tool room which are necessary to have in a workshop as given below:-
Milling Machine – It can perform versatile operations ranging from simple tasks like slot and keyway cutting, planning, drilling to complex tasks like contouring, dies sinking etc.
Grinding Machine – It also known as grinders are used to grind metals and other materials in a workshop. A grinder is very useful in a metal workshop as it helps in making metal chips from sheet metals which are used in many applications.
Shaping Machine – As the name suggests, It is used to shape metals in a workshop by removing unwanted material from the flat metal surface. It is used when large amount of metal is to be cut to form a specific shape.
Slotting Machine – It is used to make slots needed on the screw heads, bolts, wood screws and other industrial components. The most common use is in manufacturing process of automobiles, electrical components, furniture etc.
Bandsaw Machine – These are used to cut long bars in irregular shapes, straight cuts or curved shapes. This provides maximum accuracy with minimum wastage.
Hacksaw Machine – These are used to cut metals with high efficiency speed and accuracy. These are used where high pressure is required, whereas mechanical and semi-hydraulic hacksaw are used wherever low pressure is required.
How to Select Tool Room Machines for a Workshop?
Each and every workshop is different and needs to complete different types of processes. Similarly, each and every tool room unit also has different uses. If a workshop works on majority of metal grinding projects, then it may require grinding equipment and if it is working on majority of metal cutting projects, then it may require a hacksaw equipment installed. If your workshop requires completing versatile projects involving cutting and drilling both, then a milling device would be just perfect. Thus, the choice of tool room devices to be installed in your workshop depends on the majority of the projects you are handling. Many times it happens that a particular tool room is over occupied and another tool room unit is staying idle for hours altogether. This can increase the production costs of the workshop and reduce the profits. So, it is very much important to judge the kind of projects you are going to handle in your workshop in future and select tool room machines accordingly.
Buying Tool Room Machines
Buying tool room equipments for your workshop can be a crucial decision and needs to be taken carefully. If you fail to buy quality tool room devices, you may end up paying more on maintenance costs which can have an adverse effect to your returns on investment. If you need to cut down on your maintenance costs, never buy used tool room equipments, instead always go for new tool room provided by reliable manufacturer of tool room like Bhavya Machine Tools which is an ISO 9001:2008 certified company.
Press brake is an important tool which is widely used in cutting metals in various shapes and sizes. It helps in forming predetermined bends in metal sheets by clamping the material between matching punch and a die. Thus, it uses some kind of force to bend or shape the metal in a particular form. The shapes formed in the metal with the help of it are extremely accurate but it also depends on the kind of die used and ability of the operator. It is a wonderful asset to any workshop, provided it is used correctly. If it is not operated in an effective manner, the result may be not accurate and the end product produced will be of low quality. The combination of the right kind of punch, die and knowledge of the operator can enable a press brake to give an accurate output.
Uses of Press Brake
Press brake is used in the manufacturing process of various housing products, automobiles, heavy equipments etc., where bending of metal sheet is required. The metal sheet once bended or shaped out of press brake is used in various manufacturing industries producing products used in our day to day life. The press brakes are available in various sizes to handle sheets of various sizes and thicknesses. Depending on the size and the thickness of the sheet metal, the type of press brake is used.
Types of Press Brake
There are various types of press brakes available like mechanical press brake and hydraulic press brake. Mechanical press brake enables easier overloading but doesn’t enable the operator to adjust the stroke level while the process is in continuation. One has to complete the process and then adjust the stroke length. A skilled operator is required to use mechanical press so that precision in the end product can be achieved. In 1970s, the hydraulic press brake started replacing mechanical press brake because of its affordable costs and safety advantages. However, using hydraulic press brake resulted to high quality products manufacturing which benefited many manufacturing units. Due to this, hydraulic press brake became popular amongst all the press brake machines available in the market.
The mechanical press brake is made of iron whereas, hydraulic press brake is made of steel. As the hydraulic press brake is made of 100% steel, its structure is much more firm than a mechanical press brake. This eliminates the built-in stress in a hydraulic press brake and so the machine can be used for the longer period of time.
Hydraulic press brake uses hydraulic system, which is much more superior than a mechanical system as its power output is stable and its repairing services can be found locally.
In hydraulic press brake, there are two cylinders controlling the beam’s vertical moving.
Hydraulic press brake under the CNC system can be controlled by the computer which results into accurate and fast production.
In hydraulic press brake, the gauge is controlled by the electric device with the digital panel in the front. So, you can enter the data or manually adjust according to the aiming point.
So, now if you are planning to buy a press brake, make sure that you read the manual and go through its features and after that only you can decide the type of press brake to be purchased. Always go for a perfectly designed press brake which consumes less power and incurs low maintenance costs.

Metals are casted into different shapes and sizes and used for various applications. This shaping and metal forming process is usually carried out with the help of various kinds of machinery in industries like automobile, engineering, electronics etc. Some of the widely used categories of metal forming equipment include lathe machines, press brakes and grinding machines.
A lathe machine for metalworking applications comes in various forms and specifications. There are light duty, medium and heavy duty, roll turning and all geared lathe used to carry out different metal shaping tasks in different industries. While light duty lathes are widely preferred for low volume metal shaping tasks like in tool rooms, the medium and heavy duty lathe are usually preferred for industrial applications where bulk metal forming is the requirement. There are different uses with lathe. It can be used to cut, drill, knurl and deform different kinds of metals. Metals can be shaped to create objects that have symmetry about an axis of rotation.
Press brakes are common at the workplaces where metal bending is performed. With a press brake, metal sheets and plates can be bent and shaped to different dimensions and sizes accurately. A press brake forms predetermined bends by clamping the work piece between a matching punch and die. The shape of die determines the shape to which metal is bent. Therefore for performing shaping of metals to different shapes usually different kinds of dies are used. Press brake for metal bending now comes in different forms and specifications. Mechanical as well as hydraulic press brakes are two widely used forms of metal bending press brakes. Mechanical are generally preferred for low volume tasks where as the hydraulic ones are apt for large volume metal formations.
Grinding machine in metal forming applications is widely used to grind metals for better surface finish. It is very easy to work on the metals which must show high surface quality and high accuracy of shape and dimension. It like jig grinders can also be used for grinding holes and pins where as the belt grinders are apt for applications like finishing, deburring, and stock removal. Apart from these there are tool & cutter grinding machine which are best for low volume tool room applications and also the cylindrical grinders that are widely used in industries for making precision rods, tubes, bearing races, bushings, and many other metal parts.
Metal shaping and sizing is a big industries which needs heavy machine tools to differently shaping a cutting of the metals. Handling with tools are totally mechanical works with electrical integration. In this process metal work piece is carved by the industrial machine tools as per the required shape and size to be performed by unique types of tools specialized in cutting and shaping the metal as per the needs. In this article, it is discussed about very few useful metal types of machinery used in various industries frequently on daily basis to prepare the metal work pieces in new forms.
Slotting Machine: Slotting and shaping are the functionality of this machine. Solid metal parts are cut through mounted cutting tool with movable table parts to move the metal part back and forth to slot at various angles. It is widely used in industrial manufacturing of T-slotted metal, grooves and metal curved parts.

Sheet bending is a process of metal forming through which metals are bent into desired forms. In a sheet bending process the metals are casted into the required form by exerting a strong force on them. The force applied on the metal actually causes it to deform along one axis only but by applying the force repeatedly with a sequence of different operations the metals can be deformed along multiple axes thus forming the shape desired out of the metal piece.
In the process, the metal experiences both tension as well as compression. The tension will cause the outer part of the work piece to stretch further in the length where as the inside portion will experience the compression and will be shortened due to the force exerted. Apart from these two factors, the metal will also be subjected to residual stresses after the bending and these forces will try to slightly get back the metal to its original shape. For this reason the metal is often subjected to a little much bending than required so that the accurate sheet bending can be acquired in spite of the residual stresses acting on it.

Shaping Machine for Shaping the Metal Surfaces
It is used to shape metal surfaces with straight and/or flat surface. Various metals like steel, ferrous/non-ferrous metal parts, aluminium are used with this machine for casting in different curves, angles and shapes. Continue reading →
Metal Bending and Shaping Machines – Press Brake, Lathe Machine
Basically two types of equipments are widely used in metal forming industries. One is sheet bending and other is lathe. A sheet bending machine is the one that bends metal sheets into miraculous shapes whereas the lathe machine is used to create metal work pieces with evenness about an axis connected with rotation.
Different kinds of sheet bending are employed for various metal bending and shaping tasks in industries. Press brakes and power press are the popular ones.
Press brake is a special kind of sheet bending tool in which strain is exerted by the upper punch tool is on the material placed on the die tool at the bottom. The material gets deformed as per the shape of the die. If the die is U-shaped the metal will deformed to U shape and if V-die is used then metal will be bent into V-shape. Depending on the type of force used to exert strain on the material, It is classified into various categories; mechanical, hydraulic, pneumatic and servo-electric devices. In mechanical press brake, electric motor is the source of energy used to empower the flywheel that is engaged by clutch to power a crank mechanism that moves the ram vertically to perform bending job. The advantage of mechanical press brake is that accurate tasks can be performed much faster but the problem is the control over the motion of the ram which cannot be easily stopped at any required time as that in the hydraulic ones. The hydraulic press brakes that are operated by synchronized hydraulic cylinders are safer and energy saving metal benders in which ram motion can be stopped at any time. On the other hand pneumatic and servo-electric machines that operate by air pressure and servo motors respectively are generally preferred for low tonnage applications.
These are used to lower, press, fold and kind sheet metal into various shapes and sizes. These are usually equipped with parts like shaft, gears, clutch, table and ram to enable for easy, quick and precise sheet bending operations. C type power press and pillar type power press are the popular categories of power press used in industries.
Apart from bending, metals are also shaped to create axis symmetrical objects and this task is accomplished with the help of lathe machines. It is a tool which rotates the work piece on its axis and various operations such as cutting, sanding, knurling, drilling, or deformation are performed with tools on the work piece to create an object that is symmetrical about the axis of rotation. Different kinds like CNC lathe, roll turning lathe and all-geared lathes are generally employed in industries to accurately shape out different kinds of metals as per requirements. Lathe machines with best features can accurately device out even the hardest metal into a functional work piece.
Different kinds of machines are employed for sheet metal forming tasks in industries like lathe, sheet bending, power press, press brakes etc.
It is a special kind of sheet bending machine that is designed to meet tougher metal bending requirements in industries. It applies direct strain about the metal sheet and alters it to the desired form. It is commonly utilized all over the entire world to mold all types of metals into different designs. Aluminum, brass, copper, steel, tin, nickel and titanium are some common metals which can be bent into desired shapes using a press brake.
To bend metal using press brake it is first of all inserted in the jaws of press brakes. It is placed between the two tools of machine called punch and die. Punch is the upper tool which exerts force on metal sheet and bends it, while the die is the lower tool of the machine having a specific design. It is in this design that the metal will be casted. For bending, the sheet is placed on the die and held in place by the back gauge while the punch lowers and forces the sheet to bend according to shape of the die. Once this is done, in normal cases the sheet tries to regain its normal position because of the residual stresses acting on it and therefore the sheet is usually over-bent to achieve a proper bend angle.
There are basically three basic types of bending performed using a press brake; air bending, bottoming and coining. In air bending, material is formed by pressing a punch into the material into a bottom V-die. Disadvantage of this method is that it is not as precise as other methods and stroke depth must be kept very accurate. Variations in the thickness of the material and wear on the tools can result in defects in parts produced. Bottoming is similar to air bending. Here also the sheet is forced against the V opening in the bottom tool but the advantage of this method is that it provides greater accuracy and less spring back than air bending. A different tool set is needed for each bend angle, sheet thickness, and material and therefore in general, air bending is the preferred technique in this case. The third process is coining in which the top tool forces the material into the bottom die with five to 30 times the force of air bending. It causes a permanent deformation through the sheet with very little or approximately no spring back at all. This means that with coining high precision can be attained but due to its higher costs it is not often used.
To perform bending, today different ranges are available in the market. Depending on the type of force used for bending, there are 4 different type of brakes; mechanical, pneumatic, hydraulic, and servo-electric. Depending on accuracy, speed and quantity of bending to be performed, one can select the best one for their applications by considering factors like work pieces to produce, inner radius required, accuracy, tooling, flange width etc.
Press brake is also known as “Brake press” or “Break” is a machine tool for bending sheet and plate material. It is described using two parameters – working length and force or tonnage. Who can operate the machine would depend on one’s knowledge and skill about this cannot be done by an ordinary and inexperienced person in the field.
Types of Press Brake
It is defined in several categories based on applied force like mechanical, pneumatic, hydraulic and servo electric press brake. A mechanical press is advantageous in terms of speed and accuracy. Pneumatic and servo-electric machines, on the other hand are used for lower tonnage work or applications. Furthermore, hydraulic brakes are used to produce high quality products that are reliable and use little energy.
Applications of Press Brake
Press-brake forming is an art, and greatly dependent on operator skill. Therefore, it is expected that varying levels of quality and productivity are to be achieved by two different operators. Consequently, inconsistent results are also accepted and need more attention for consistency. Higher differencing parts are reworked, scrapped or simply passed to the next stage.
It is very useful for sheet metal bending. The produced sheet metal afterwards will then be useful for a wide array of applications in the manufacturing industry. These produced sheet metals are used in home appliances, vehicles, in heavy equipments, these sheet metals are sure to be functional on everyday lives of people. But before the right sheet metals are formed, sheet metal benders should first consider the right die design to produce the right sheet metal. These are used in many different forming jobs with the right die design like V dies, rotary bending dies, acute angle dies, radius dies etc. In a mechanical press, energy is added to a flywheel with an electric motor. A clutch engages the flywheel to power a crank mechanism that moves the ram vertically. Accuracy and speed are two advantages of the mechanical press brake. Hydraulic press brake operates by means of two synchronized hydraulic cylinders on the C-frames moving the upper beam.
Mechanical press brake offers a rigid ram level and easier to overload and difficult to bring ram close to material for scribed line work. Skilled operator needed to slip clutch for adjusting. Mechanical brake presses don’t enable you to adjust the stroke length. One must complete the revolution and cycle the machine completely.
Hydraulic press brake is safe and more expensive. These types of brakes are slower and have more precision bend work with better control when inching down and setting up for your bend, they can return to the top any time. These are easy to operate and provide simplified and easy controls for optimum output with better operator efficiency.
