Research on material removal rate in ultrasonic vibration cylindrical lapping Al_2O_3 ceramics

研究了Al2 O3 陶瓷试件的超声振动研磨特征 ,分析超声研磨中加工参数与试件材料去除率的关系。经研究得出 :在相同的加工条件下 ,超声振动研磨加工比普通研磨加工 ,材料去除效率高 ,去除率随工件转速的增加而增加 ,随着转速的增加 ,去除率的斜率有所下降 ;保证材料去除率达到最大的研磨压力存在一个最佳值 ;粗粒度油石研磨加工去除效率较细粒度的高 ;细磨粒油石超声研磨工件表面粗糙度值小于粗磨粒研磨工件。同时与普通研磨相比较 ,超声研磨加工不仅效率高、且加工工件表面粗糙度值较小。

This article introduces the devices and the machining principle of ultrasonic vibration cylindrical lapping,combining with the lapping experiments of Al 2O 3 ceramic samples,analyses the relationship between vibration lapping parameters and remove rate of ceramic samples At the same time,comparing with common lapping,it concludes that the machining efficiency and work piece surface roughness of ultrasonic vibration lapping is more higher and smaller than those of common lapping
