Milling refers mainly used various milling machine on the workpiece surface. Typically cutter rotational motion-based motion artifacts (and) moving cutter for feed motion. It can be machined flat, groove, it can process a variety of surfaces, and other gear. Milling cutters with workpiece milling machine. Milling in addition to milling plane, grooves, teeth, thread and spline shaft, but also more complex type of surface machining, high efficiency than planer tapping multi-axis CNC drilling machine, machinery manufacturing and repair department are widely used. 19th century, the British Industrial Revolution to the needs of the steam engine and other inventions of the boring machine, planer, and the Americans in order to produce large quantities of weapons, the dedicated milling machine was invented in. Milling machine is a machine with cutter shapes, it can be cut out of the workpiece multiaxial supply drilling tapping special shape, such as a helical groove, gear shape. Back in 1664, British scientists Hook rotating circular cutting tool manufacturers to rely on a machine for cutting, which can be regarded as the original multi-axis milling machine tapping drilling companies, but then did not make this passionate community repercussions. In the 1840s, Pratt designed the so-called Lincoln milling machine. Of course, the really established position in the milling machine manufacture, to count the Americans Whitney. Machine classification edit an ordinary machine: including lathes, drilling, boring, milling, planing, slotting, etc; 2, precision machine tools: including grinders, gear cutting machines, screw machine tools and various other precision machine tools; 3, high-precision machine tools: including coordinate boring, gear grinding, thread grinding, high-precision hobbing machine, high-precision machine engraved lines and other high-precision machine tools; 4, CNC machine: CNC machine tools is called digital control machine tools; 5, according to the workpiece size and weight of the machine can be divided for instrumentation tools, small tools, large-scale machine tools, heavy and super heavy machine tools; 6, according to the processing accuracy can be divided into ordinary precision machine tools, precision machine tools and precision machine tools; 7, according to the degree of automation can be divided manually operated machine tools, semi-automatic machines and automatic machine; 8, according to the machine control, can be divided into profiling tools, process control machine tools, CNC machine tools, adaptive control machine tools, machining centers and flexible manufacturing systems; CNC multi-axis drilling tapping, tapping multi-axis drilling Chen Hua machinery provided by China Machinery Co., Ltd.
