A kind of manufacturing method of complex busbar polishing wheel with local reinforcement structure

Abstract

The invention provides a complex generatrix polishing wheel with a local reinforcement structure. The complex generatrix polishing wheel comprises three different structures including a direct electroplating polishing wheel body, an electroplating abrasive cloth forming polishing wheel structure and an abrasive material block polishing wheel body. By adding the necessary reinforcement structure or enhancement materials into abrasive materials and elastic base bodies, the bonding force of the abrasive materials is enhanced, and the local supporting strength of the abrasive materials is controlled. A method specifically comprises the step that diamonds and other superhard abrasive materials are solidified to the surfaces of the base bodies of the metallic or non-metallic reinforcement structure through the electroplating or sintering methods, and the diameter of the base bodies is about 1 mm or smaller. The reinforcement structure has the hardness obviously higher than that of a polishing wheel base body and the geometric dimension far larger than that of the abrasive materials. The small abrasive material blocks are solidified to rubber of the polishing wheel bodies or other types of soft base bodies through the bonding or other proper methods, so that the polishing wheel with the reinforcement structure is formed, the abrasive materials of the polishing wheel protrude easily, and the polishing wheel has a sufficient grinding effect. The problems that conventional polishing wheel abrasive materials are small in size and bonding force, capable of easily sinking into the base bodies, prone to falling off, low in grinding capacity and the like are solved.

Description

【Technical field】 [0001] The invention relates to a complex generatrix polishing wheel with a local reinforcement structure and a manufacturing method thereof, which is used to solve the problem that the polishing effect of various polishing wheels is reduced due to the fact that the extremely fine abrasives are easy to fall off and be easily squeezed into the flexible polishing wheel matrix , At the same time, superhard diamond and cubic boron nitride abrasives can be used to greatly extend the life of the polishing wheel, and solve the problem that the current polishing wheel has a short life and is difficult to apply to the automatic polishing process. The invention belongs to the technical field of superfine polishing processing. 【Background technique】 [0002] Polishing is a typical superfinishing process. Polishing can not only significantly improve the aesthetics of the machined surface, but also greatly improve the fatigue strength of parts and prolong their working ...
