Abstract

The invention discloses a novel wear-resistant planetary grinding disc, and belongs to the technical field of hard alloy composite sheet processing. The novel wear-resistant planetary grinding disc iscomposed of a grinding flower disc (1) and a grinding basal disc (2), wherein 10-36 uniformly distributed through holes are formed in the grinding flower disc (1), and a wear-resistant plastic ring (3) is tightly nested inside each through hole; counter bores which are as many as the through holes in the grinding flower disc (1) are formed in the grinding basal disc (2), and a cylindrical diamondcomposite sheet (4) is arranged in each counter bore by braze-welding; and three or more screw through holes (5) are further formed in the same position on the grinding basal disc (2) and the grinding flower disc (1) for fixing the grinding basal disc (2) and the grinding flower disc (1). While the novel wear-resistant planetary grinding disc is used to process a hard material, working time can be effectively reduced, diamond abrasive materials are saved, manpower and material resources are saved, and product quality is improved.

Description

technical field

[0001] The invention belongs to the technical field of cemented carbide composite sheet processing, and specifically relates to a novel wear-resistant planetary grinding disc, in particular to a planetary grinding disc containing diamond composite sheets and wear-resistant plastic parts, which is applied to diamond composite sheets, cubic nitrogen A tool for surface grinding of superhard materials such as boron compound sheets. Background technique

[0002] At present, the diamond / cubic boron nitride composite sheet is sintered together with diamond micropowder or cubic boron nitride and cemented carbide substrate (tungsten carbide-cobalt alloy) under high temperature and high pressure, and the upper part is diamond / cubic boron nitride polycrystalline layer. The working layer has ultra-high hardness and ultra-high wear resistance, and the lower part is hard alloy. During the production and processing of diamond / cubic boron nitride, a very important step is t...
