Abstract

The invention discloses a grinding wheel block, a preparation method thereof and a polishing grinding wheel. The grinding wheel block is prepared from, by volume, 16%-22% of diamond grinding materials, 15%-22% of phenolic resin, 15%-22% of polyvinyl butyral resin, 31%-49% of cerium oxide and 3%-7% of copper powder. According to the grinding wheel block, a mixture of the phenolic resin and the polyvinyl butyral resin is used as a binding agent, the cerium oxide is used as a polishing optimization component, and the polishing efficiency and surface smoothness can be improved through the combined action of the binding agent, the polishing optimization component and the diamond grinding materials; the copper powder has a toughening function, and the grinding performance is improved; through the compounding of the phenolic resin and the polyvinyl butyral resin, both the strength and tenacity are guaranteed through the binding agent, force generated due to blockage and surface contact can be buffered when zirconia ceramic is ground, and a good polishing function is achieved; the grinding wheel block is suitable for machining materials with high surface smoothness.

Description

technical field [0001] The invention belongs to the field of superhard materials and products in mechanical processing, and in particular relates to a grinding wheel block and a preparation method thereof, and a polishing grinding wheel. Background technique [0002] Zirconia (ZrO 2 ) is a new type of ceramic material with excellent mechanical properties, thermal properties, insulation properties, corrosion resistance, ion conductivity, optical properties, etc. ZrO 2 The relative density is 5.65g / cm 3 , melting point is 2715℃; ZrO 2 The strength of the ceramic material can reach 650Mpa, the elastic modulus can reach 283Gpa, and the microhardness can reach 13.2Gpa. It has the characteristics of high hardness, toughness and bending strength, and good optical performance, wear resistance and heat insulation performance. Because the coefficient of thermal expansion is close to that of metal materials, zirconia ceramics are widely used in structural ceramics. In addition to ...
