床身导轨加工,目前大多采用端面磨削。因不易实现冷却,故对影响精度的主要原因──热变形则难于排除。同时表面光洁度和导轨形貌也不太理想。 我们在普通六米龙门刨床上经适当改装,用分步成型周边磨削的方法加工 C 616 A精密普通车床的床身导轨,取得了较好的效果。迄今已使用三 Bed rail processing, the current use of face grinding. Due to difficult to achieve cooling, so the main reason for the accuracy of the impact ─ ─ thermal deformation is difficult to rule out. At the same time the surface finish and rail morphology is not ideal. We are in the ordinary six-meter gantry planer by the appropriate modification, with the step-by-step peripheral grinding C 616 A precision lathe bed rail, and achieved good results. So far has been used three
