Problems solved by technology

[0002] The characteristic of grinding is that the abrasive is constantly rolling during the grinding process, producing two effects of extrusion and cutting. During the processing of the workpiece, as the contact area between the abrasive paste and the workpiece continues to increase, some grinding motion and The grinding paste does not adhere well to the surface of the workpiece and reduces the efficiency of grinding
The emergence of these problems will make the processing of workpiece materials difficult, especially for some precision devices and devices requiring high surface finish.

Abstract

The invention relates to diamond lapping paste and a preparation method thereof. The diamond lapping paste is composed of artificial diamond micro powder, vaseline, diesel, oleic acid, graphite, stearic acid and polytetrafluoroethylene. The diamond lapping paste disclosed by the invention has excellent lapping and polishing properties, is fine and smooth in paste body and has an excellent effect of polishing sapphire lens materials.

Description

Technical field [0001] The invention belongs to the technical field of material polishing and grinding. More specifically, the present invention relates to a diamond polishing paste, and also relates to a preparation method of the diamond polishing paste. Background technique [0002] Grinding is characterized by the continuous rolling of the abrasive during the grinding process, resulting in both extrusion and cutting. During the processing of the workpiece, as the contact area between the grinding paste and the workpiece continues to increase, there will be some grinding immobility and The grinding paste cannot adhere well to the surface of the workpiece, which reduces the grinding efficiency. The emergence of these problems will make the processing of workpiece materials difficult, especially for some precision devices and devices that require high finish on the surface of the material. [0003] In order to better solve the defects of the prior art, the present invention, base...
