对于较大型发动机的机体,常要求与淬硬的钢套组合后再进行内孔及内端面的精磨加工(图1)。一般内圆磨床难以胜任,我们在 T 68镗床上采用自制的卧式行星内圆磨具,较顺利的完成了钢套的磨削任务。 磨具的基本结构 磨具完成砂轮的自转、公转、径向进给、轴向往复等运动(图2)。 公转 For larger engine body, often require hardened steel sleeve after the combination of the inner hole and the inner end of the surface grinding (Figure 1). General Internal Grinder difficult to perform, we use the T 68 boring machine with homemade horizontal planetary circular grinding tools, the successful completion of the steel sleeve grinding tasks. The basic structure of abrasive tools to complete the grinding wheel rotation, revolution, radial feed, axial reciprocating movement (Figure 2). Revolution
