How are mechanical and hydraulic press brakes employed for sheet metal bending?

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.

During the process of manufacturing parts, metal apparatus etc.  metal is shaped into different forms. It can fold or bend the sheet of metal into any given shape. Cases for goods like electronics are made with it. Click Here to get more information on mechanical and hydraulic press brakes.


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.

Features of a Sheet Bending Machine

With a sheet bending machine you can bend a sheet of metal. The whole sheet can be placed on the surface and bent according to your requirement to make metal structures. Pressure is applied to the metal sheet in order to bend it. Metal can be bent and converted into a new shape.

These are extensively used in many industries such as automobiles and manufacturing industry. Different types of sheet bending tools with diverse features are available.

Features of a sheet bending machine:

Also known as a brake, a sheet bending machine is used to make big right angles as well as curved folds. It is also used to shape metals in the required shape and size. High pressure exerted on the metal part causes it to deform and take the desired shape or the bend. Press brake is the basic form of this.

It has a flat surface on which the sheet to be bent is placed. The clamping bar holds the material firmly while it is being bent. The clamping of the sheet can be done manually, automatically or by using a foot pedal.

The metal to be shaped is placed between ‘punch and dies’ tools. The punch or the upper tool exerts pressure on the metal sheet and the die the base tool is formed into the shape which the metal will take when the force will be exerted.

The front plate of the device, is hinged and can be lifted like a gate. It forces the sheet to follow the plate in order to bend. The bends can be made up to 120°.

The clamping bar in a cornice brake is one solid piece, which is the size of the full length of the unit and it can make only straight bends. The complete width of the sheet can be bent.

A box and pan brake has a clamping bar with many blocks that can be removed. These blocks can be removed and arranged again to bend a particular area of the sheet.

These are available in different sizes depending upon you requirement. There are small devices for molding light metals like aluminum and brass which are operated by hand. For large sheets of steel there are industrial size machines which are hand operated or hydraulic.

It is hand operated have body made of cast iron. These have a handle, a bending bar and a bending blade to make folds on the metal sheets. Different dies are used to create different bends like rotary bending dies, V dies, radius dies, acute angle dies etc.

In a mechanical sheet moulding, an electric motor supplies energy to the flywheel which in turn powers the crank to move the ram vertically. This is accurate and fast to work.

Hydraulic sheet bending use two hydraulic cylinders to move the upper beam. These are fast and efficient tools.


As technology advances, the tools also advance in design and use. We have to select machines according to our requirement. A wide range of sheet bending equipments is available in the market. As a consumer we have to make our choice wisely.

Difference between CNC turret Milling machine and a normal milling machine

Milling is the process by which rotating cutters remove extra material from a metal or wood piece of work to give it a definite shape by means of a machine. It is a frequently used process in the industry and unit shops for shaping parts to exact shape and size. It works on the law of rotary motion. The multi teeth cutter spins around the axis at a high speed and as the work piece moves ahead the blades shear pieces off it. These are vertical mills or horizontal mills and under the category of vertical mills there are turret mills and bed mills.

Difference between CNC turret mills and normal milling machines:

• The cutting process in CNC turret milling is controlled by a computer where as in normal milling it is manual which can lead to human error.

• CNC mills are more versatile than normal mills. A number of jobs that are not possible with normal mills can be easily done with CNC mills.

• The movement along the Z-axis in a CNC turret mill allows precision cutting, like engraving, which cannot be done in a normal mill.

• CNC turret milling are smaller in size and are more compact as compared to a normal mill.

• In a CNC mill the spindle is stationary and the table can move parallel as well as perpendicular to the axis of the spindle for the cutting process. Where as in a normal milling machine the spindle rotates on its axis and the cutters are held in it.

• Turret mills have a quill which lets the cutter move up and down like in a drill press.

• As the CNC mills are programmed with a computer the work pieces are consistent in design, size and finish even if a large number of pieces are made. This is not possible in a normal mill.

• Complex work pieces can be made with turret mills as these equipments can produce versatile movements and so complicated shapes can be made with these mills which are not possible with normal mills.

• Work done with CNC machines is faster than a normal mill so more work pieces can be made in less time.

• CNC turret mills can work nonstop, for 24 hours a day throughout the year where as a normal milling device needs to be stopped.

• Less skilled workers can operate a CNC mill but only a trained and skilled engineer can operate a normal mill.

• Once the CNC turret mills are programmed they can work on their own and one person can supervise them. But for each normal mill one engineer is needed to operate it. Click here to know more about CNC turret Milling machine.


A CNC turret milling machine is worth the money you invest in buying it for your work. This versatile device can make your work much easier and faster. You just need to program the equipment once, and feed in the design in the computer and you can make any number of identical objects in a short time.
