The drive gears adopt high quality alloy steel, after heat treatment and lappingfinish.
传动齿轮采用优质合金钢，经热处理，研磨而成。

Therefore, it is a new way for difficult-to-cut material to deep-hole finish machine by applying ultrasonic vibration machining technology to deep-hole lapping.
因此，将超声振动加工技术应用于深孔研磨加工中，为难加工材料的深孔精加工开辟了一条新的途径。
