我厂产品中有一薄壁套零件:材料为40Cr,硬度为HRC24～30。本工序是磨內孔至成品尺寸。在本工序前外径工艺尺寸φ101.4_0~(+0.05);两端面对外径已达到工艺需要的垂直度要求,误差小于0.04mm;总长已达到图纸尺寸119mm;待磨削的內孔留有余量(单面)0.2mm。
My factory products have a thin-walled parts: the material is 40Cr, hardness HRC24 ~ 30. This process is to wear the hole to the finished size. Before the process diameter of the outer diameter of φ101.4_0 ~ (+0.05); both ends of the outer diameter has reached the process requirements of the verticality requirements, the error is less than 0.04mm; total length has reached the size of the drawing 119mm; Balance (single) 0.2mm.
