一般外圆磨床或曲轴磨床加工轴类工件的表面粗糙度,只能达到R_α0.63～0.32μm。为改善工件轴颈(例如内燃机曲轴主轴颈和曲柄销轴颈)的表面粗糙度,以提高其疲劳强度,我们采用了粒度较细的油石进行抛光。由于缺乏专用的抛光机,所以我们设计了简易的轴类工件抛光工具,配上必要的夹具后,就可在普通车床上进行外圆抛光了。 General cylindrical grinder or crankshaft grinding machine shaft surface roughness of the workpiece, can only reach R_α0.63 ~ 0.32μm. In order to improve the surface roughness of the work piece journals (such as the crankshaft journals and crankpin journals of the internal combustion engine) in order to increase their fatigue strength, we used a less granular whetstone for polishing. Due to the lack of a dedicated polishing machine, we designed a simple shaft-type workpiece polishing tool, with the necessary fixture, you can on the ordinary lathe cylindrical polishing.
