The development of milling machine


The milling machine was first made by the American E. Whitney in 1818 to create a horizontal milling machine. In order to milling the spiral groove of the twist drill, the American J.R. Brown created the first universal milling machine in 1862, which was the prototype for the milling machine. A gantry milling machine appeared around 1884. In the 1920s, semi-automatic milling machines were introduced, and the workbench used the stoppers to perform automatic conversion of "feed-fast" or "fast-feed".

After 1950, the milling machine developed rapidly in the control system, digital control applications greatly improve the degree of automation of the milling machine. Especially after the 1970s, the microprocessor's digital control system and automatic tool changer system in the milling machine has been applied to expand the milling machine processing range, improve the processing accuracy and efficiency.

With the increasing process of mechanization, NC programming began to be widely used in machine tool operation, which greatly relieved the labor force. CNC programming milling machine will gradually replace the manual operation. The staff requirements will be higher and higher, of course, the efficiency will be higher and higher.
