Abstract

The invention relates to the technical field of insulating ceramics machining. In order to solve the problems that the conventional insulating ceramic machining method and device are low in machining accuracy and low in quality of the machined surface, the invention provides a method for machining insulating ceramic by reciprocating wire-cut electrical discharge machining. The method comprises the following steps of: immersing insulating ceramics of which the outer surface is fixed with an auxiliary electrode in electrospark liquid or kerosene working solution; putting a wire electrode into the working solution, connecting the auxiliary electrode and the wire electrode to the anode and cathode of a high-frequency pulse power supply respectively, and controlling the distance between the auxiliary electrode and the wire electrode until electrical discharge can be realized; and controlling relative motion between the wire electrode and the insulating ceramics according to the machining requirement. The invention also provides a device, wherein the insulating ceramics of which the outer surface is fixed with the auxiliary electrode and the wire electrode are arranged in the electrospark liquid or kerosene working solution and are connected with the anode and cathode of the high-frequency pulse power supply respectively; and the insulating ceramics are fixed on a work table and are driven by the work table to move. The method is stable in machining process and favorable for popularization and application.

Description

Technical field: [0001] The invention relates to the technical field of insulating ceramic processing, in particular to a reciprocating wire electric discharge wire cutting processing method and device for insulating ceramics. Background technique: [0002] Ceramic materials have high strength, high hardness, high temperature resistance, wear resistance, corrosion resistance and good chemical stability. As functional materials in the 21st century, they are used in automobiles, aircraft, steam turbines, engines, aviation, aerospace, machinery, Electronics, electrical engineering, communications, semiconductors, medical and health industries have broad application prospects. However, due to the characteristics of high hardness and high strength of ceramic materials, it is particularly difficult to process them with traditional mechanical processing methods. From the perspective of the application of engineering ceramics, the processing cost can account for more than 80% of the...
