超高强度不锈钢薄壁件的加工较难控制,需要选择合适的夹具和制定优良的切削工艺才能控制精度和形位公差。使用0Cr18Ni9型超高强度不锈钢材料的某飞机起落架上的胀管零件如图1所示,该零件前期工序为挤压成型,外形已经加工完毕,需在数控车床上加工该胀管的内表面,单边加工余量0.365mm。 Ultra-high-strength stainless steel thin-walled pieces of processing more difficult to control, need to select the appropriate fixture and the development of good cutting technology to control the accuracy and shape tolerance. The use of 0Cr18Ni9-type ultra-high strength stainless steel material on the landing gear of an aircraft expansion pipe parts shown in Figure 1, the parts pre-process for the extrusion molding, the shape has been processed, the CNC lathe to be machined on the inner surface of the tube , Unilateral machining allowance 0.365mm.
