Description

technical field

[0001] The invention relates to the technical field of ultra-precision machining, and more specifically, to an electro-Fenton cluster magnetorheological compound grinding and polishing device and method. Background technique

[0002] Due to its high strength, high hardness, high brittleness, wear resistance and corrosion resistance, heat insulation, low density and low expansion coefficient and stable chemical properties, hard and brittle materials are widely used in electronics, optics, instrumentation, aerospace, civil and military industries, etc. The application potential in this field is huge. With the development of modern high technology, the demand for planar hard and brittle materials is becoming more and more extensive, but the surface quality of hard and brittle materials has become a key factor restricting its application. Brittle materials have the disadvantages of low plasticity, brittle failure, microcracks and improper processing technology, ...
