超声波振动车削是近几年发展起来的一种比较先进的精密车削方法。此方法克服了普通车削切削阻力大、切削热大、工件变形大、自激振动和刀具磨损快等要害问题,从而为精密车削和超精车削开辟了崭新的道路。一、超声波振动车削机构超声波振动车削是把超声波振动能量附加在车刀上,使车刀产生具有一定频率和振幅的高频机械振动,并且使车刀上下振动的方向和工件的
Ultrasonic vibration turning is a more advanced precision turning method developed in recent years. This method overcomes the key problems of large turning resistance, large cutting heat, large deformation of workpiece, self-excited vibration and fast tool wear, which opens a new path for precision turning and super turning. First, the ultrasonic vibration Turning mechanism Ultrasonic vibration Turning is the ultrasonic vibration energy attached to the lathe, the lathe tool to produce a certain frequency and amplitude of high-frequency mechanical vibration, and make the tool up and down the direction of vibration and the workpiece
