High and low frequency compound vibration processing device and method oriented to hard and brittle material

Abstract

The invention provides a high and low frequency compound vibration processing device oriented to a hard and brittle material. The device comprise an ultrasonic vibration cutter handle, a cutter installed on the ultrasonic vibration cutter handle through a driving coil, a low-frequency vibration platform used for placing a part to be processed, a waveform generator and a piezoceramic driving powersupply, wherein the waveform generator and the piezoceramic driving power supply are connected with the low-frequency vibration platform. The device has the characteristic of a simple structure. The invention also provides a high and low frequency compound vibration processing method oriented to the hard and brittle material. According to the method, a relative movement way and a contact conditionof a workpiece and the cutter are improved to effectively reduce subsurface stratum damage depth and improve the surface quality of a processed part, and the processing requirements of a high-qualityhard and brittle material part can be met.

Description

technical field [0001] The invention belongs to the field of precision special processing, and in particular relates to a high-low frequency composite vibration processing device and method for hard and brittle materials. Background technique [0002] Hard and brittle materials such as ceramics, glass, and crystals have been used in space technology, energy engineering, mechanical engineering, automobile industry, petroleum, chemical industry, metallurgy, textile industry and biological industries due to their low density, heat resistance, wear resistance, and corrosion resistance. It has been widely used in medical engineering and other fields, and has become an indispensable new material in high-tech fields such as modern industry, national defense and aerospace. [0003] However, due to the particularity of hard and brittle materials, conventional machining methods are difficult to process parts. At present, the high-frequency vibration processing technology using ultras...
