Resin diamond grinding wheel

Abstract

The invention discloses a resin diamond grinding wheel. The grinding wheel comprises a substrate and an abrasive layer, wherein the substrate is an annular aluminum substrate; the abrasive layer is anannular resin binder diamond layer; the abrasive layer is embedded in and concentrically arranged with the aluminum substrate; the grinding wheel also comprises an annular steel substrate, which is arranged at the lower end of the aluminum substrate and concentrically arranged with the aluminum substrate; and the steel substrate and the aluminum substrate are connected by gluing or screws. The substrate is connected with the aluminum substrate by gluing or screws, strength of the substrate is enhanced, and the defects of large dynamic balance and insufficient assembly space caused by increasing of strength of the substrate in the prior art are overcome, so that dynamic balance of the diamond grinding wheel is better in the grinding process, and the diamond grinding wheel is stable in useand better in grinding effect.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a resin diamond grinding wheel. Background technique [0002] At present, the edging of architectural ceramic glazed tiles usually requires fine edging with diamond grinding wheels to achieve a flat and smooth effect around the tiles. Existing diamond grinding wheels generally include a substrate and an abrasive layer, the abrasive layer is embedded on the substrate, the substrate is made of an aluminum substrate, and the abrasive layer is made of a resin bonded diamond layer. However, as the amount of ceramic processing increases, the cutting amount of the diamond grinding wheel also increases, resulting in greater grinding resistance during the use of the diamond grinding wheel. The existing conventional diamond grinding wheel is difficult to meet the production needs. [0003] In order to meet the long-term stable use of the product under high-strength cutting conditio...

AI Technical Summary

Problems solved by technology

However, in the prior art, the general die-casting aluminum material often has uneven density in the case of large volume, so increasing the thickness of the substrate also brings the defects of too small assembly space and too large dynamic balance. Further affect the edging quality of ceramic glazed tiles

In addition, in the prior art, other materials are used to replace the aluminum matrix to increase the strength of the matrix, but this will also lead to a series of other problems

For example, the iron matrix is ​​used to replace the aluminum matrix to increase the strength of the matrix, but the bonding performance between the iron matrix and the resin bond diamond abrasive layer is weak, which causes the abrasive layer to fall off during the grinding process of the grinding wheel; if the titanium matrix is ​​used instead of aluminum Substrate, due to the high cost of titanium materials, the cost of the product has increased significantly, etc.
