Diamond resin grinder

Abstract

The invention relates to a diamond resin grinding tool in the field of grinding tool technology. The working layer is formed by diamond grinding material, catalyst, and filler; the diamond grinding material adopts self-sharpening diamond grinding material which has working layer volume rate 12.5-31.25úÑ.The working layer also comprises: hardening carbonizable substance with volume rate 5-15úÑ and admixture formed by carbite 0-3úÑ.The hardening carbonizable substance comprises: one or two combines of silicon carbide, boron carbide, titanium carbide, and tungsten carbide; the hardening oxide substance comprises: aluminum oxide or / and silicon oxide. The catalyst chooses phenol resin or polyimide resin which has working layer volume rate 40-50úÑ; the filler chooses copper, chromic oxide, zinc oxide and iron oxide which have working layer volume rate 8-15úÑ, 5-15úÑ, 0-8úÑ, 0-8úÑ.

Description

technical field

[0001] The invention belongs to the technical field of abrasive tools, in particular to a diamond resin abrasive tool. Background technique

[0002] The diamond resin abrasive tool includes a working layer, which is made of a needle-shaped diamond abrasive, a resin binder, and a filler composed of copper powder, chromium oxide, zinc oxide or iron oxide powder. In this abrasive tool, the needle-shaped The diamond abrasive is shaped like a needle piece, with a smooth and flat surface, and is not firmly bonded to the bond, so it is easy to fall off prematurely during the working process of the abrasive tool; the hardness and wear resistance of the filler are low, causing the abrasive tool bond to wear too quickly. Therefore, the abrasive tool has a shorter service life. Contents of the invention

[0003] The object of the present invention is to provide a diamond resin abrasive tool with sharp grinding and long service life.
