Abstract

The invention discloses special polishing liquid for a diamond compact and a preparation method of the special polishing liquid, and belongs to the field of precise and ultra-precise polishing. The special polishing liquid is developed to solve the problem that common polishing liquid cannot meet ultra-precise mirror finishing of ultrahard materials including the diamond compact and the like. The polishing liquid is prepared from the following materials according to certain volume ratios: 5% of a brightening agent, 5% of diamond micro powder, 10% of Vaseline, 20% of mixed fat and 60% of kerosene; and a diamond compact workpiece processed by the polishing liquid is uniform in surface quality, does not have polishing defects and can achieve a mirror polishing effect. Meanwhile, the polishing liquid can also achieve effects of cooling, lubricating, adsorbing and cleaning during processing, can also be used for mirror polishing processing of similar ultrahard materials, and is simple to operate, high in efficiency, low in cost and pollution-free.

Description

technical field [0001] The invention belongs to the technical field of precision ultra-precision grinding and polishing, and mainly aims at the special grinding and polishing fluid developed for similar super-hard materials such as diamond composite sheets, so as to meet the requirements for precision / ultra-precision processing thereof. Background technique [0002] Diamond composite sheet is sintered with diamond micropowder and cemented carbide substrate under ultra-high pressure and high temperature conditions. It not only has high hardness, wear resistance and thermal stability, but also has high strength and impact toughness. It is a manufacturing It is an ideal material for cutting tools, drilling bits and other wear-resistant tools. It is widely used in petrochemical, geological exploration, aerospace, medical and machining tools, and has important commercial and military application values. However, it is precisely because of its series of advantages that the process...
