      Introduction To Milling Machine

      Release:rhqqzmkm Browse:28

        Milling machine refers to a machine tool that mainly uses milling cutters to process various surfaces on a workpiece. Usually the rotation of the milling cutter is the main movement, and the movement of the workpiece (and) the milling cutter is the feed movement. It can process planes, grooves, various curved surfaces, gears, etc. A milling machine is a machine tool that uses a milling cutter to mill a workpiece. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex profiles. The efficiency is higher than that of planing machines. It is widely used in machinery manufacturing and repair departments.

        In the 19th century, the British invented the boring machine and planer for the needs of industrial revolution such as the steam engine, while the Americans devoted themselves to the invention of the milling machine in order to produce a large number of weapons. A milling machine is a machine with milling cutters of different shapes, which can cut workpieces with special shapes, such as spiral grooves, gear shapes, etc.

        As early as 1664, the British scientist Hooke relied on rotating circular cutters to create a machine for cutting. This can be regarded as a primitive milling machine, but the society did not respond enthusiastically to this. In the 1840s, Pratt designed the so-called Lincoln Milling Machine. Of course, it is American Whitney that really establishes the status of milling machines in machine manufacturing.

        The first ordinary milling machine (Whitney, 1818). In 1818, Whitney manufactured the world's first ordinary milling machine. However, the patent for the milling machine was obtained by British Bodmer (the inventor of the planer with a tool feeding device) in 1839. Due to the high cost of the milling machine, there were not many people interested at that time.

        The first universal milling machine (Brown, 1862). After a period of silence, the milling machine became active again in the United States. In contrast, Whitney and Pratt can only be said to have done groundbreaking work for the invention and application of milling machines. The achievement of truly inventing milling machines that can be applied to various operations in factories 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 was an epoch-making initiative in terms of the provision of universal index plates and integrated milling cutters. The worktable of the universal milling machine can rotate at a certain angle in the horizontal direction, and is equipped with accessories such as an end milling head. The "Universal Milling Machine" he designed was a great success when it was exhibited at the Paris Exposition in 1867. At the same time, Brown also designed a form milling cutter that would not be deformed after grinding, and then manufactured a grinder for grinding milling cutters, bringing the milling machine to this level.
