Abstract

The invention provides a production process of an interface-modified high-strength, environment-friendly and heavy-duty grinding wheel. The abrasive and auxiliary materials are subjected to nano-modification treatment, and the treatment agent is nano-silicon and carbon particles. Calcium, magnesium compounds and activated carbon particles are blended with modified abrasives, auxiliary materials and resin powder. The invention realizes the outstanding advantages of high strength, no odor, ultra-low porosity and high grinding performance of the heavy-duty grinding wheel, making the product catch up with Japan and the United States and reach the international leading level.

Description

technical field [0001] The invention belongs to the field of grinding wheel production, and in particular relates to a production process of an interface-modified high-strength, environment-friendly and heavy-duty grinding wheel. Background technique [0002] At present, ordinary heavy-duty grinding wheels produced by domestic manufacturers are usually simply hot-pressed with resin, abrasives and auxiliary materials. Their strength and grinding performance are relatively low, and ammonia gas will be generated during production, which will seriously pollute the environment and damage the health of workers; Moreover, since the linear speed used by the heavy-duty grinding wheel reaches 80m / s, and a pressure of 10000N is required for grinding during use, if the product strength is not enough, it will cause major safety accidents, which will cause harm to equipment and people. great harm. [0003] Moreover, with the strong entry of foreign products, domestic products are far inf...
