Abstract

The invention discloses a boron-carbide-based ceramic material cutting processing system and method. The boron-carbide-based ceramic material cutting processing system comprises a cutting machine tool, a direct-current power supply, an auxiliary electrode, a boron-carbide-based ceramic workpiece and an electrolyte. The boron-carbide-based ceramic workpiece is made of boron-carbide-based ceramic materials; the direct-current power supply, the auxiliary electrode, the boron-carbide-based ceramic workpiece and electrolyte constitute an electrolytic system. The boron-carbide-based ceramic workpiece is clamped on the cutting machine tool and connected with the positive pole of the direct-current power supply. The auxiliary electrode is connected with the negative electrode of the direct-currentpower supply, and the electrolyte is sprayed between the auxiliary electrode and the boron-carbide-based ceramic workpiece. According to the boron-carbide-based ceramic material cutting processing system and method, electrochemical action is used for corroding the surfaces of the boron-carbide-based ceramic materials, and the cutting processing of the boron-carbide-based ceramic materials is achieved in combination with the 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 with boron carbide (B 4 C) As a base material, a sintering aid (additive) is added, and the sintering is formed 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. They cannot be processed by cutting methods such as turning and milling, and can only be processed by grinding. and grinding methods for precision machining. Since the processing is prone to cracks and slag, the cutting parameters must be controlled in the grinding process, and the processing efficiency is extremely low. Contents of the invention [0003] The purpose of the ...
