Edging wheel and fabricating technique

Abstract

An edge grinding wheel unit is composed of a metallic grinding disc, diamond cutters, and metallic connectors between said grinding disc and diamond cutter and with a locating block extended in said diamond cutter. Its manufacture technology includes such steps as loading the diamond powder in a mould, putting the metallic connectors in the mould, compacting, cold pressing, hot pressing, demoulding to obtain an assembly, machining the assembling annular step on a metallic grinding disc, installing the assemblies, and butt-welding.

Description

technical field The invention relates to an edging wheel and a manufacturing process thereof. Background technique At present, diamond edging wheels are widely used in the cutting and polishing of stone and hard and brittle non-metallic materials. The diamond cutter head and the grinding disc are usually connected by welding methods, such as high-frequency heating welding and silver brazing. These welding methods will cause diamond The cutter head is reheated, and the temperature of this reheating is very close to the hot pressing temperature of the diamond cutter head, and its heat-affected zone is relatively large, so it has a significant impact on its performance, and even greatly reduces the use of the diamond cutter head In addition, due to the consumption of a large amount of flux and silver electrodes during brazing, the production cost is relatively high, and the working environment of production workers is relatively harsh, and they must be in the high temperature o...
