Abstract

The invention relates to a special grinding fluid for grinding of silicon carbide ceramic by diamond grinding wheels. The special grinding fluid comprises 4.8%-6.2% of fatty acid methyl ester polyoxyethylene ether, 2.5%-2.9% of an alkyl synthol alkoxy compound, 2.2%-2.5% of tungsten disulfide, 4.2%-4.4% of cyclopentasiloxane, 3.5%-3.7% of an anti-wear reagent at extreme pressure, 2.3%-3% of a corrosion inhibitor, 2.5%-3.5% of a friction modifier and the balance of deionized water. The special grinding fluid for grinding of the silicon carbide ceramic by the diamond grinding wheels has excellent lubricating, cooling and cleaning effects, has the long service cycle and can substantially reduce the grinding temperature, the normal grinding force and the tangential grinding force in the machining process of the silicon carbide ceramic, reduce abrasions of the grinding wheels, effectively improve surface quality and precision of ground surfaces of the silicon carbide engineering ceramic and the like.

Description

technical field [0001] The invention belongs to the field of grinding processing of ceramics, and in particular relates to a special grinding fluid for grinding silicon carbide ceramics with a diamond grinding wheel and a preparation method thereof. Background technique [0002] With the development of science and technology, especially energy and space technology, engineering ceramics have attracted widespread attention and been used in high-tech engineering fields due to their superior properties such as high strength, low expansion rate, wear resistance and chemical stability. Engineering ceramic materials are made of powder raw materials and then sintered at high temperature. The inevitable blank sintering shrinkage and special shape requirements make engineering ceramic parts need to be machined to meet the tolerance requirements of size and shape and surface roughness. degree requirements. [0003] Silicon carbide ceramic materials have low manufacturing costs, short ...
