Abstract

The invention aims at providing a diamond grinding wheel working layer material and a preparation method thereof so as to solve the problems that an existing ceramic matrix diamond grinding wheel is poor in hot hardness, processing strength is limited, processing efficiency is low, and the like. The diamond grinding wheel working layer material is formed by Ni4W intermetallic compounds, metallic aluminum and diamond and comprises, by mass, 65%-75% of Ni4W intermetallic compounds, 15%-20% of metallic aluminum and 10%-15% of diamond. The metallic aluminum and the Ni4W intermetallic compounds are interdiffused to form an Al-W-Ni brittle phase component. The Ni4W intermetallic compounds high in thermal stability, strength and hardness serve as a key component of a diamond grinding wheel working layer bounding agent, and the problems that the existing ceramic matrix diamond grinding wheel is poor in hot hardness, the processing strength is limited, the processing efficiency is low, and the like are solved.

Description

technical field [0001] The invention relates to a working layer (diamond layer) material of a diamond grinding wheel used for processing cemented carbide blades and a preparation method thereof. Background technique [0002] At present, the working layer of the commonly used diamond grinding wheel is generally prepared from diamond abrasives and resin, metal or ceramics as a binder, and the working layer is consolidated on a circular substrate with a through hole in the center to prepare The ultimate diamond grinding wheel. [0003] The diamond grinding wheel prepared by resin bond has the disadvantages of low strength of the bond itself and insufficient holding force of diamond, which causes the diamond particles to fall off easily. At the same time, due to the elasticity of the resin itself, the dimensional consistency of the processed object is poor, and the noise is large during processing. The problem. The diamond grinding wheel made of metal bond is difficult to shar...
