A kind of diamond resin grinding wheel and mold and method for processing the grinding wheel

Abstract

The invention relates to a diamond resin wheel and a mold and a method for machining the resin wheel. The resin wheel comprises a base body and abrasive material layers, wherein the abrasive layers are at least two abrasive layers which are fixed on the surface or the outer circle of a base body through extrusion and hot pressing, and each abrasive layer is formed by mixing and pressing differentcoarse and thin diamond particles and a binding agent; and the bonding position of the abrasive material layers and the base body are adopted with a dovetail-type structure, and the bonding faces arefurther processed into rough surfaces; the mold comprises a positioning base, a mold frame and a center mold, wherein the inner wall of the mold frame and the bottom face of the center mold form a placement area of the diamond resin wheel base body, a gap for installing a pressure head is arranged between the inner wall of the mold frame and the outer wall of the center mold, and the center mold is assembled with an assembling rod in a fixed mode through a fastening nut to be limited; the method for machining the resin wheel comprises the following steps that 1) the resin wheel base body is prepared; 2) the base body is fixed; 3) the abrasive material layers are pressed in advance; 4) hot-pressing forming is carried out; and 5) shaping and manufacturing are carried out. According to the method, a specially designed mold and a machining mode are adopted, so that the resin wheel with multiple utilization can be produced, and the grinding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a diamond resin grinding wheel, a mold and a method for processing the grinding wheel. Background technique [0002] Grinding wheel is the most important type of abrasive tool in grinding process. The grinding wheel is a porous body made by adding a binder to the abrasive, compacting, drying and firing. Grinding wheel is the most widely used type of grinding tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing and Fine grinding as well as grooving and parting off etc. But at present, in the grinding operation, rough grinding, semi-finishing and fine grinding need to be processed by multiple processes respectively, and different grinding wheels need to be replaced according to the needs of grinding, which leads to a high occupation rate of equipment resources and low work efficiency. [0003] At present, mold molding is used when process...

AI Technical Summary

Problems solved by technology

However, most of the existing grinding wheels are single-process grinding wheels, that is, in the grinding operation, different grinding wheels must be replaced according to the rough grinding, semi-finishing or fine grinding process. Therefore, the processing and production of grinding wheels are also processed and produced separately. bring a lot of inconvenience

And most of the existing grinding wheels adopt the structure combined with the base and the abrasive layer. How to make the base and the abrasive layer effectively bond during the processing and production of the grinding wheel can simplify the processing flow and improve the production efficiency of the grinding wheel, especially the multi-abrasive layer grinding wheel.
