History of Milling Machine

Milling MachineRotary filling was the first in base of invention of the first milling machine that reduced the efforts need to put on hand filling and save the time. The development history is still unclear as the variety of custom machines performing the functions of milling machine were available in individual shops and factories before. Rotary milling was the ancestor of first. It is a unique machine tools first manufactured during 1814 to 1818 in two federal armories of the USA.

James Nasmyth is the famous name who built the advanced milling machine during 1829 to 1831, ahead of it’s time to mill the six sides of hex nut. Gay & silver also used a prototype of milling machine for vertical milling which was a better method than earlier milling versions. Till then milling machine was a part of production machine and not toolroom machines.

1840 to 1860 was the era of designing for successful milling machine by Lincoln Miller. Different companies were making the milling machines on the common configuration. George S. Lincoln & Company first put the true commercial milling machine in the market on 1855. Based on the company, the name to machine was given as milling machine.

Brown & Sharpe’s were the first to make universal milling machine in 1861, which was unique in design and function itself. This patented machine the milling cutters use to sharpen the teeth did not change the form geometry.

Joseph W Roe, the founder of many machine tools has created the first true milling machine in co-ordination with Eli Whitney, the private arm maker during 1912 to 1916. Robert S. Woodbury and other scholars had improved the design and functioning of the Roe’s first true milling machine. Robert Johnson, Cap. John H. Hall, Simeon North, Roswell Lee and Thomas Blanchard are the few names of researchers and engineers who had contributed in development and improvement in the previous type of milling machine.

From 1870 to the mid of twentieth century till first world war, the various other forms of milling machines came into existence like universal milling machine for tool room, jobbing and production use.

After World War I, new advanced versions including jig machines and milling machine with CNC technology have come up with various milling features and functionalities.

How to Use Lathe Machine?

Basically, a lathe machine is a tool used to shape metals.The material is rotated in the cylindrical motion and then touches a cutting tool to it which cuts the material. The metal sheet is fixed on the chuck of the lathe machine and then the chuck rotates in the vertical direction as well as right and left direction and touching byte’s tip to the material to cut the metal. The original lathe machine when invented used to complete tasks like cutting cylindrical metal sheets and then it was further developed to produce screw threads, tapered work, drilled holes, knurled surfaces, and crankshafts. The modern lathe machines available nowadays, offer the facility of rotating speeds as well as adjusting manually and automatically the cutting tool. There are different types available like light duty, medium duty, heavy duty, extra heavy duty, all geared, imported, CNC, roll turning and many more. No matter what type it is, you need to follow the below given basic instructions while using it.

  • You need to ensure that it should not be started cold. First of all, warm up the lathe machine for 10 minutes, setting its speed up to 1000 rpm. It should also be well lubricated and you need to check all the tools and ensure that they are tight.
  • Now, the tool holder should be located and tool block should be inserted in it. The spot is supposed to be located in the tool block where you can insert a cutter. Also for safety reasons, you need to tighter the tool block as tighter as you can. The cutters allow the users to cut from left to right, which is also known as cutting on a Z axis.
  • The tail stock is to be located where drill chuck can be inserted. The tail stock is very useful as it helps in drilling holes in the metal. The crank at the end of the measuring device helps in performing precision depths to the cuts.
  • The next step would be to set your zero and stop the turning spindle. You need to get a tool holder and put in at least 0.5 inch block between the tip of your tool and the metal sheet. Slide the tool holder in and out on an X axis to tighten it. The micrometer wheel should be set to zero.
  • Also you need to set your X zero point by pulling the Z axis tool towards the spindle and slide 0.5 inch block between the tool and the work piece. You also need to set the X axis micrometer to zero and turn the wheel 0.5 inch away.
  • So, now if you want to cut 0.5 inches from the metal sheet keep X axis and Z axis both 0.25 inches away from the metal sheet and then start the spindle.

Safety Measures to be Taken While using a Lathe Machine

  • You need to get dressed correctly by rolling your sleeves above the elbow. Also remove rings and watch if you have worn.
  • Before making any adjustments to the tools, always remember to stop the machine.
  • Spindle speeds should not be changed until it has come to a complete stop.
  • Always wear protective eye glasses.
  • While the metal sheet is turning, never try to measure the cut.
  • Never lean on the it.

What is Press Brake?

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.

In Conclusion

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.
