Milling machines refer to machines that use milling cutters to machine a variety of surfaces on a workpiece. Usually the rotary motion of the milling cutter is the main movement, and the movement of the workpiece (and) milling cutter is a feed movement. It can process planes, grooves, as well as various 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 splined shafts, milling machines can also process more complex profiles with higher efficiency than planers and are widely used in the machinery manufacturing and repair department.
In the 19th century, the British invented boring machines and planers for the needs of the industrial revolution such as the steam engine.
Produce a large number of weapons, then concentrate on the invention of the milling machine. A milling machine is a machine with a variety of milling cutters that can cut special shaped parts such as spiral grooves, gears, etc.
As early as 1664, the British scientist Hooker relied on rotating circular cutters to create a machine for cutting, which could be regarded as a primitive milling machine, but at that time the society did not respond enthusiastically. In the 1940s, Pratt designed the so-called Lincoln milling machine. Of course, the real establishment of the status of the milling machine in the machine manufacturing must be American Whitney.
The first ordinary milling machine (Whitney, 1818) In 1818, Whitney made the world's first ordinary milling machine, but the patent for the milling machine was British Bodmer (a gantry with a delivery device). The inventor of the planer) was the first to win in 1839. Due to the high manufacturing cost of the milling machine, there were not many people who were interested.
The first universal milling machine (Brown, 1862) After a certain period of silence, the milling machine became active again in the United States. In contrast, Whitney and Pratt could only say that they laid the groundwork for the invention of the milling machine. The invention of a milling machine that can be applied to various operations in the factory should be attributed to American engineer Joseph Brown.
In 1862, Brown of the United States produced the world's first universal milling machine. This type of milling machine is an epoch-making initiative in terms of universal indexing disks and integrated milling cutters. The table of the universal milling machine can be rotated in a horizontal direction by a certain angle, and has an attachment such as a vertical milling head. When he designed the "Universal Milling Machine" exhibited at the Paris Exposition in 1867, he achieved great success. At the same time, Brown also designed a shaped milling cutter that will not be deformed after grinding, and then also produced a milling cutter grinding machine, so that the milling machine has reached such a level.
