补充资料：超精加工
| 超精加工 superfinishing 用细粒度的磨条以一定的压力压在旋转的工件上，并在轴向作往复振荡进行微量切削的光整加工方法。超精加工一般安排在精磨工序之后进行，其加工余量很小（一般为5～8微米），常用于加工各种内外圆柱面、圆锥面、平面、球面等，如曲轴、轧辊、滚动轴承套圈和各种精密零件等。工件经超精加工后，表面粗糙度可达R0.08～0.01微米，表面加工纹路由波纹曲线相互交叉形成，从而易于形成油膜，提高润滑效果，因此耐磨性较好。由于切削区温度较低，表面层有轻度塑性变形，所以表面带有低残余压应力。超精加工常用的磨条粒度一般为W0.5～W28；常用的切削液为80％左右的煤油加20％左右的机油，并经严格过滤；磨条压力一般为0.05～0.3兆帕；磨条振幅一般为1～6毫米；工件圆周速度一般不超过700米／分。若需要提高零件的形状精度及去掉磨削变质层，必须去掉余量0.03毫米左右，此时采取将超精加工分为粗精两阶段，粗加工时用较粗粒度的磨条、较大转速和磨条压力，精加工时取较小的值。
