Producing a large number of weapons, they are dedicated to the invention of the milling machine. Milling machine is a machine with different shapes of milling cutters, which can cut special shaped workpieces, such as spiral grooves, gear shapes, etc.
As early as 1664, the British scientist Hook relied on a circular tool to create a machine for cutting. This was a primitive milling machine, but at that time the society did not respond enthusiastically.
In the 1840s, Pratt designed the so-called Lincoln milling machine. Of course, the true establishment of the milling machine in machine manufacturing must be counted by American Whitney.
The first ordinary milling machine (Whitney, 1818) In 1818, Whitney manufactured the world’s first ordinary milling machine, but the patent for the milling machine was the British Bodmer (gantry planer with a knife feeding device) The inventor) first won in 1839. Because the cost of milling machines was too high, there were not many people at the time.
The first universal milling machine (Brown, 1862) became active in the United States after a period of silence. In contrast, Whitney and Platt can only say that they have laid the groundwork for the invention and application of milling machines. The achievement of truly inventing milling machines that can be used in various operations of the factory should belong to the American engineer Joseph Brown.
In 1862, Brown of the United States produced the world’s earliest universal milling machine. This milling machine is an epoch-making pioneer in providing universal indexing discs and comprehensive milling cutters. The table of the universal milling machine can rotate a certain angle in the horizontal direction, and is equipped with accessories such as an end milling head. His “Universal Milling Machine” was a great success when it was exhibited at the Paris Expo in 1867. At the same time, Brown also designed a form milling cutter that will not deform after grinding, and then manufactured a grinding machine for the milling cutter to bring the milling machine to the current level.
