Milling machine is the machine tool that undertakes to workpiece with milling cutter milling is machined. Milling machine is divided can outside milling plane, groove, teeth of a cogwheel, whorl and spline axis, still can machine more complex model face, efficiency relatively planing machine is expensive, be made in machinery and repair a branch to get applied extensively. The earliest milling machine is American the horizontal milling machine that benefit spy Buddhist nun contrived 1818; For the helix chamfer of broach of milling fried dough twist, american Braun contrived 1862 the first all-purpose milling machine, this is the rudiment of lifting platform milling machine; Around appeared again 1884 planer-type milling machine; 20 centuries 20 time appeared semi-automatic milling machine, workbench uses link stopper achievable " feed - definitely fast " or " definitely fast - feed " automatic changeover. After 1950, milling machine develops in control system respect very fast, digital pilot uses the automation rate that raised milling machine greatly. Especially after 70 time, control system mixes the number of microprocessor to change knife system automatically to get applied on milling machine, enlarged the size range of pipe bent of milling machine, rose to machine precision and efficiency. Milling machine is a lot of more phyletic, it is to press layout form and suitable scope to try to distinguish commonly, basically milling machine of lifting platform milling machine, planer-type milling machine, odd column and thin arm milling machine, appearance milling machine, tool milling machine waits. Lifting platform milling machine has all-purpose type, horizontal and vertical a few kinds, basically use at treatment medium or small spare parts, application is the widest; Planer-type milling machine includes He Shuangzhu of planer of mill of door of boring machine of dragon door mill, dragon milling machine, all use at machining large part; The horizontal milling head of milling machine of odd column horizontal can move along pillar slideway, workbench makes fore-and-aft feed; Of thin arm milling machine establish milling head to be able to move along cantilever slideway level, cantilever also can adjust height along pillar slideway. Odd column milling machine and thin arm milling machine all are used at machining large part. Appearance milling machine is milling machine of lifting platform of a kind of diminutive, use at machining instrument appearance and other and small-sized spare parts; Tool milling machine basically is used at mould and tool to make, deserve to have establish a variety of accessory such as workbench of milling head, all-purpose angle and outlet, still can undertake getting cutting, boring and insert cut wait for treatment. Other milling machine still has milling machine of keyway milling machine, cam milling machine, crankshaft milling machine, roller journal milling machine and square steel ingot to wait, they are makes to process corresponding work special milling machine. Additional, press control means, milling machine can be divided again wait for profile modeling milling machine, programme controll milling machine and CNC Milling. CNC MillingCNC Machining
