Milling cutter on the workpiece are used to carry out milling machine. In addition to milling machine milling plane, groove, gear, thread and spline shaft, but also processing more complex type of noodle, efficiency than the planer the highest in the machinery manufacturing and repair sector has been widely applied.
The earliest milling machines are American Whitney in 1818 to create the horizontal milling machine; for milling helical groove of the first twist drill, American Brown in 1862 to create the first universal milling machine, milling machine This is the embryonic form of lifting platform; 1884 appeared before and after the gantry milling machine; twenty-first century emerged during the 20 semi-automatic milling machine, table block to be completed by the use of "feed - never speed" or "must-speed - into to the" automatic conversion.
In 1950, the milling machine in the control system has developed rapidly, the application of digital control milling machines greatly increased the degree of automation. Especially the 70s, the microprocessor digital control system and automatic tool changing system in milling has been applied to expand the scope of the milling process, improve the machining accuracy and efficiency.
A lot of milling machine types, the general is based on the layout of the form and make a distinction between the scope of application, the main platform has milling machine, Gantry milling machine, single-column and single-arm milling machine milling machine, milling machine instrumentation, tools such as milling machine.
Lifting platform has universal-type milling machine, horizontal and vertical ways, mainly used for processing small and medium-sized parts, Longmen milling machine bed and double are used for machining large parts; single the level of column milling machine milling head can move along the guide column, table for vertical feed; arm milling machine's position along the cantilever milling head can guide the level of movement, the cantilever can also be adjusted along the guide column height. Single column and single-arm milling machine milling machine for processing large parts are.
Milling instrument is a small milling machine lifting platform for the processing of instruments and meters and other small parts; tool die milling machines and tools mainly used in manufacturing, with a Li-milling head, universal angle plug, such as workstations and a variety of attachment, but also for drilling, boring and slotting processing. There are other milling keyway milling, cam milling machines, crankshaft milling machine, roll neck and side milling milling machine, such as ingots, which are for the processing of the workpiece corresponding to manufacture special milling machine.
In addition, according to control mode, can be divided into profiling milling machine milling machine, milling machine and CNC controlled milling machine and so on.
