Milling of 5 coordinate high speed machines the crucial technology of the machine tool

One, introductive
Cutting of numerical control high speed made a technology promote the flying development of manufacturing industry of mechanical cold working, innovated products plan concept, if pass,use whole the fraction that treatment replaces component make assemble, rose to machine efficiency and product quality, shortened the product makes cycle. High speed cutting quickened the product such as car, mould, aviation, spaceflight, optical, accurate machinery change, quickened production technology and equipment upgrade, drove industry technology progress. But at present domestic existence comparatives machine tool of one part high speed does not have the result that achieves ideal because of the reason of each respect, like cutting tool configuration does not follow to go up and low speed is used, main shaft of high speed report carries on his shoulder or back because of bearing burden for a long time or use undeserved create life low, library of parameter of craft of cutting of enterprise high speed and package of software of process designing of CADCAM high speed cause high speed cutting to apply is not very good, technological process of high speed cutting and traditional technological process do not have organic union, without sufficient play treatment of high speed cutting is out of shape outfit of tall, fixed position places efficiency of small, treatment little advantage.

The characteristic of machine tool of high speed milling, those who use structure of main shaft campaign to realize load is smooth, those who because move,reduce workbench is inertial, bear the weight of when workbench especially bigger when, the athletic load of workbench itself and workpiece causes impact extremely easily to high speed cutting, the novel sex of machine tool structure is having main effect to high speed cutting, the shift of the XY direction that traditional machine tool relies on workbench shift to realize a machine tool is not to suit high speed cutting very much. High speed machine tool has axis of HyperMach5 of company of Cincinnati of VCP710 of Swiss Mikron company, United States SMM of company of Mazak of machining center, Japan - 6 coordinate of KR214 of company of FIDIA of RFM1000 of company of Roders of 2500UHS, Germany, Italy 5 coordinate of D218 of company of machining center, FIDIA machining center.

Usually, its cutting speed compares high speed cutting groovy speed tower above 5 ～ 10 times, the 3 ～ that the purify rate of its material is groovy cutting 5 times above. To aluminium alloy milling can achieve 1100m/min above, cast-iron can arrive 700m/min, rolled steel can arrive 380m/min above, auger cut 200 ～ 1200m/min, grinding 150 ～ 360m/min. Use FIDIA KR214 machine tool of machining center of milling of 5 coordinate high speed and machine tool check and accept a standard to try cut a product.
