Brown corundum resin grinding wheel and preparation method thereof

Abstract

The invention discloses a brown corundum resin grinding wheel and a preparation method of the chrome corundum resin grinding wheel. The brown corundum resin grinding wheel is prepared from the following components by weight, 50-60 parts of brown corundum grinding material, 5-10 parts of white corundum grinding material, 5-10 parts of diamond grinding material, 5-15 parts of phenolic resin powder, 2-6 parts of phenolic resin liquid, 1-2 parts of tritolyl phosphate, 5-10 parts of nano celestite powder, 5-10 parts of bauxite, 2-5 parts of borax and 2-5 parts of copper powder. According to the brown corundum resin grinding wheel, as the ceramic material is added into padding, the adhesive property is good, the grinding materials hardly fall off, the heat resistance and hardness of the resin grinding wheel are improved, cracks formed by rigid grinding are reduced, and the use efficiency and service life of the resin grinding wheel are improved further; in addition, as the copper power is added, fast heat dissipation effect is achieved, a great deal of heat generated in the cutting process of the grinding wheel can be dissipated quickly, and the effect of lowering cutting temperature is lowered.

Description

technical field [0001] The invention relates to a brown corundum resin grinding wheel and a preparation method thereof, which belong to the technical field of grinding tool processing. 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. The substance used to bond the abrasive in the grinding wheel is called a bonding agent. The performance of the bonding agent determines the strength, impact resistance, heat resistance and corrosion resistance of the grinding wheel. At present, the binder is mainly divided into four types: ceramics, resin, rubber and metal. Among them, the resin binder has high strength, ...

AI Technical Summary

Problems solved by technology

We know that the proportion of brown corundum abrasives involved in the grinding of resin grinding wheels is only about 10% so far. Most of the brown corundum abrasives have poor bonding with them, are heated during the grinding process, or are affected by external forces. The falling off, which greatly restricts the use efficiency and life of the resin grinding wheel
