抛光是提高工件光洁度和精度的一个重要加工方法。目前我国的绝大多数工厂仍使用五十年代的普通抛光法,效率低,抛光质量较差,耗能、耗原材料较多,劳动强度大。近来,我们对国外的超声振动抛光做了些粗浅的探讨性试验研究,现就超声振动抛光的机构、机理、工艺参数作一简略的介绍,供参考。一、超声振动抛光机构超声振动抛光主要是把超声振动附加在抛光工具或工件上,从而使工具或工件以一定的频率(20～50KHz),一定的振幅(10～30μm)做高频的机械振 Polishing is an important tool for improving the finish and accuracy of workpieces. At present, most factories in China still use the common polishing method of the 1950s, which has the disadvantages of low efficiency, poor polishing quality, more energy consumption and consumption of raw materials, and greater labor intensity. Recently, we made some superficial and exploratory experimental studies on ultrasonic vibration polishing in foreign countries. Now we briefly introduce the mechanism, process and parameters of ultrasonic vibration polishing for reference. First, the ultrasonic vibration polishing mechanism Ultrasonic vibration polishing ultrasonic vibration is mainly attached to the polishing tool or workpiece, so that the tool or workpiece to a certain frequency (20 ~ 50KHz), a certain amplitude (10 ~ 30μm) to do high-frequency machinery Vibration
