Problems solved by technology

[0003] Although the traditional resin diamond grinding wheel has good sharpness and self-sharpness, it has low heat resistance, insufficient wear resistance, and short dressing gap, which affects production efficiency; although the vitrified diamond grinding wheel has good sharpness, it has poor wear resistance and is difficult to dress; Although the metal diamond grinding wheel has good shape retention, its self-sharpening is not good, and it cannot meet the needs of continuous processing

Abstract

The invention discloses a diamond grinding wheel. The diamond grinding wheel is composed of, by weight, 40-60 parts of diamond grinding materials and 360-540 parts of composite binding agents, and each composite binding agent comprises, by weight, 45-50 parts of copper-coated iron powder, 20-30 parts of iron powder, 17-23 parts of copper-tin alloy powder, 7-18 parts of aluminum powder, 15-22 parts of ceramic powder and 4-7 parts of polyimide particle balls. The invention further discloses a preparation method of the diamond grinding wheel. The diamond grinding wheel not only has good diamond holding force, but also has good self-sharpening property.

Description

technical field [0001] The invention relates to the field of abrasive abrasives. More specifically, the present invention relates to a diamond grinding wheel sheet and a preparation method thereof. Background technique [0002] Grinding wheel is the main tool for grinding, which is a porous object composed of abrasive and bonding agent. Diamond abrasives are used as raw materials, and metal powder, resin powder, and ceramics are used as binders respectively. The circular bonded abrasive with a through hole in the center is called a diamond grinding wheel. [0003] Although the traditional resin diamond grinding wheel has good sharpness and self-sharpness, it has low heat resistance, insufficient wear resistance, and short dressing gap, which affects production efficiency; although the vitrified diamond grinding wheel has good sharpness, it has poor wear resistance and is difficult to dress; Although the metal diamond grinding wheel has good shape retention, its self-sharpe...
