Theoretical and Experimental Research on the Material Removal Rate in Ultrasonic Aided Lapping of ZTA Ceramic

Lower machining efficiency of traditional lapping with free abrasive restricts the enhancement of the precision parts’ production efficiency. It is necessary to improve lapping efficiency on the premise of guarantee of lapping quality. In this paper, a new ultrasonic aided lapping technology was developed by combining lapping technology and ultrasonic machining technology and a series of lapping experiments of ZTA engineering ceramic with and without ultrasonic assistance were carried out. The results of theoretical analysis and experimental study show that it is the ultrasonic assistance of the lapping tool that promotes the enhancement of lapping efficiency and the ultrasonic aided lapping technique with fixed abrasive can be regarded as a high efficiency processing method of the precision engineering ceramic part.
