Abstract

The invention discloses a grinding fluid special for precision machining ELID of an aluminum-based diamond composite material. The electrolytic capacity of the grinding fluid is improved, and an aluminum matrix and an iron-based grinding wheel in aluminum-based diamond are effectively electrolyzed. Meanwhile, a compact oxidation film can be formed on the grinding wheel and the metal surface, and a machine tool, a workpiece and a cutter are prevented from being corroded. The grinding fluid is high in aluminum-based diamond machining efficiency, low in cost, high in removal rate, good in surface quality of machined workpieces and high in machining precision. Meanwhile, the grinding fluid is green and pollution-free, has no harm to human bodies and the environment, meets the requirement for precise and ultra-precise online electrolytic finishing mirror surface machining of workpieces, and is suitable for precise machining of the aluminum-based diamond composite material.

Description

technical field [0001] The invention relates to a special grinding fluid for ELID grinding which is suitable for the field of precision ultra-precision grinding of aluminum-based diamond composite materials. Background technique [0002] Aluminum-based diamond composite material is the latest fourth-generation electronic packaging material. Compared with the third-generation electronic packaging material aluminum-based silicon carbide, the thermal conductivity of the material is improved, and the thermal expansion coefficient is reduced, which effectively improves the life and stability of electronic devices. , but the huge disparity between the reinforcement phase and the hardness of the matrix makes the traditional grinding wheel easy to be blocked by aluminum-based grinding debris and cause surface burns, and it is impossible to achieve precision machining of aluminum-based diamond. At present, the preparation technology of aluminum-based diamond composite materials is ma...
