无心磨床广泛地应用在轴承制造工业中。在生产变排球状滾子轴承的一般加工工艺过程中,大部是桶形滾子之磨削加工。轴承滾子之简图如[图一]所示。滚子是由铬鋼(ⅢX-15)制成,淬火後之硬度为Rc62～64。
Centerless grinders are widely used in the bearing manufacturing industry. In the production of variable ball bearings in the general processing of the process, most of the barrel-shaped roller grinding. The sketch map of bearing roller is shown in [Fig. 1]. Roller is made of chrome steel (ⅢX-15), the hardness after quenching Rc62 ~ 64.
