Abstract

The invention relates to a spring-grinding grinding wheel. The invention is characterized in that the grinding wheel consists of raw material and fine material; wherein, each group of the raw material comprises ZA16<#>, WA16<#>, WA30<#>, resin liquids, resin powders, lithopone, light calcium carbonates, cryolites and ferric oxides and each group of the fine material comprises A24<#>, A30<#>, A36<#>, resin liquids, resin powders, light calcium carbonates, cryolites and carbon black. Each group of the raw material and fine material are mixed to make finished materials. The finished materials can be divided into two kinds: the raw material is used for grinding with lower hardness and the fine material is a non-grinding part with higher hardness. When in shaping, the raw material is casted first, and the fine material is casted by three times respectively. Two web pieces are arranged in the middle for pressing, mould-disassembling and hardening. After a qualified inspection the product is the eligible product. The invention integrates two specifications and materials into a whole, with both high strength and low hardness. The invention is characterized in that the strength is high; crash can be avoided; burn to work pieces can be avoided and grinding accuracy is high.

Description

technical field [0001] The invention relates to an abrasive tool, in particular to a spring grinding wheel, which belongs to the abrasive tool manufacturing technology. Background technique [0002] Grinding spring grinding wheel is a kind of abrasive tool with resin as binder, because the parts to be processed are special spring steel with high hardness and high quenching degree. If the hardness of the grinding wheel is soft, the grinding wheel is easy to break, has poor safety, and wears quickly. If the hardness of the grinding wheel is high, although the grinding wheel is not easy to break, it is easy to burn the workpiece and affect the quality of the workpiece. There is an urgent need in the market to have a spring grinding wheel that has high strength and low hardness, high safety, good grinding effect, and does not burn workpieces. Contents of the invention [0003] The purpose of the present invention is just to overcome the above-mentioned deficiency that prior a...
