Description

technical field [0001] The invention belongs to the technical field of grinding test devices, in particular to a controllable multi-dimensional ultrasonic ELID composite internal grinding test device. Background technique [0002] Hard and brittle materials such as optical glass and engineering ceramics have the characteristics of high temperature resistance, wear resistance, chemical corrosion resistance, high temperature creep resistance, and low thermal expansion coefficient. meaning. However, due to the difficult-to-process characteristics of this material, such as high brittleness, it is easy to produce various types of damage during processing, which limits its application. In order to solve these problems, many researchers have studied the efficient ultra-precision machining methods of such hard and brittle materials in recent years, such as the prestressed processing method of hard and brittle materials, magnetic polishing technology, ultrasonic ELID processing tech...

AI Technical Summary

Problems solved by technology

However, although the multi-dimensional ultrasonic vibration grinding technology has superior comprehensive processing performance, it still has certain technical difficulties, such as unstable vibration speed when the load, temperature and other conditions change, difficulty in applying ultrasonic vibration, and problems in ultrasonic machining. The resonance frequency drifts, the vibration amplitude decreases, the processing efficiency decreases, and the processing quality is unstable. The adjustment of its resonance state involves a series of problems such as the matching of multiple ultrasonic generators, transducers, tools and workpieces, which is difficult to implement manually.
