Abstract

The invention discloses a special grinding wheel for cleaning and grinding a right angle and a manufacturing method thereof. The special grinding wheel for cleaning and grinding the right angle is primarily prepared from the following components in percent by weight: 40% of polyimide resin powder, 33.3% of Cu, 5% of MgO, 8.2% of Cr2O3, 4.0% of Sic, 3.1% of Na3ALF6, 0.33g / cubic millimeter common diamonds and 0.55 g / cubic millimeter carbonado. The manufacturing method of the special grinding wheel for cleaning and grinding the right angle comprises the following steps: S1, inputting the polyimide resin powder, Cu, MgO, Cr2O3, Sic, Na3ALF6, common diamonds and carbonado according to a certain proportion in a ball-milling barrel holding hard alloy balls to be ball-milled for 2-5 hours. All materials are mixed uniformly. Through testes and use for many times, the right angle of a product ground by the diamond grinding wheel produced by the process can be lower than R0.05 and needs not be processed again, so that the cost can be saved by 50%, the production period can be shortened by 30% and the pure profit of the product can be improved by 15-20%.

Description

technical field [0001] The invention relates to the technical field of hard alloys, in particular to a special grinding wheel for right-angle clearing grinding and a manufacturing method thereof. Background technique [0002] The cemented carbide industry is developing rapidly, and it is used in all walks of life. The shape of the products is also diversified, and the requirements for the right angle of the products are higher. The arcs of the right-angle parts of the products processed by conventional grinding are all above R0.3 or higher. For those with high requirements, they must be processed by EDM or other methods. increased. Contents of the invention [0003] The purpose of the present invention is to provide a special grinding wheel for right-angle grinding and its manufacturing method, so as to solve the problem that the arcs of the right-angle parts of the products produced by conventional grinding in the above-mentioned background technology are all above R0.3 ...
