The use of calcium carbonate in resin grinding wheels: enhancing wear and temperature resistance, moderate hardness without damaging the mold, stable friction coefficient, and high cost-effectiveness. Specially made resin bonded diamond grinding wheels are mostly used for rapid cold cutting, especially suitable for hard alloy grinding (such as iron saws, cutting machines, drilling tools, and end mills). It can also be used for fine grinding operations of hard alloy molds, drums, and carbonized wear parts.

Resin bonded grinding wheels are the preferred grinding tools for fine machining of ceramic products, as well as for grinding silicon carbide and thermal sprayed coatings on ceramic products. There are usually seven to eight or more types of fillers added together with abrasive materials, such as alumina, diamond, copper powder, etc., mainly serving as support. The main purpose of adding calcium carbonate whiskers here is to enhance wear resistance, utilizing the aspect ratio structure of the whiskers in conjunction with other high mesh size powders to increase the strength of the "support". The production process of resin grinding wheels is very similar to that of brake pads. After high-pressure forming at ℃, it usually requires insulation for one hour to eliminate internal stress. The proportion of calcium sulfate whiskers added to resin grinding wheels is 5-10% or even slightly higher. The hardness of the filler should not be too high, and our calcium carbonate whiskers have a moderate hardness that meets the requirements. In addition, the grinding layer also requires a stable friction coefficient, and our whiskers have a significant effect on the stability coefficient of the brake pads.Article source: Resin wheel manufacturerhttp://www.jm-nanhua.com
