Abstract

The invention discloses a cutting processing system and method for a boron carbide-based ceramic material. The cutting system includes a cutting machine tool, a DC power supply, an auxiliary electrode, a boron carbide-based ceramic workpiece and an electrolyte, and the boron carbide-based ceramic workpiece adopts carbonization Made of boron-based ceramic material; the DC power supply, auxiliary electrode, boron carbide-based ceramic workpiece and electrolyte constitute an electrolysis system, and the boron carbide-based ceramic workpiece is clamped on the cutting machine and connected to the positive pole of the DC power supply. The auxiliary electrode is connected to the negative pole of the DC power supply, and the electrolyte is sprayed between the auxiliary electrode and the boron carbide-based ceramic workpiece. The invention utilizes electrochemical action to corrode the surface of the boron carbide-based ceramic material, and realizes cutting processing of the boron carbide-based ceramic material in combination with a cutting machine tool.

Description

technical field [0001] The invention relates to the technical field of processing boron carbide-based ceramic materials, in particular to a cutting processing system and method for boron carbide-based ceramic materials. Background technique [0002] Boron carbide-based ceramics are based on boron carbide (B 4 C) As a base material, a sintering aid (additive) is added, and sintering is performed by pressing and heating. Boron carbide is a superhard material second only to diamond and cubic boron nitride. Boron carbide-based ceramics have the characteristics of ultra-high hardness and low fracture toughness value. They cannot be processed by cutting methods such as turning and milling, and can only be processed by grinding. and grinding method for precision machining. Because the machining is prone to cracks and slag, the cutting parameters must be controlled in the grinding process, and the machining efficiency is extremely low. SUMMARY OF THE INVENTION [0003] The purp...
