Diamond resin grinding wheel and preparation method thereof

Abstract

The invention discloses a diamond resin grinding wheel and a preparation method of the diamond resin grinding wheel. The diamond corundum resin grinding wheel is prepared from the following components by weight, 50-60 parts of diamond grinding material, 10-20 parts of silicon carbide powder, 5-15 parts of phenolic resin powder, 2-6 parts of phenolic resin liquid, 1-2 parts of dibutyl phthalate, 5-10 parts of nano fluorite powder, 5-10 parts of fungacetin, 2-5 parts of black manganese ore and 2-5 parts of scrap iron powder. According to the diamond 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 iron 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 diamond resin grinding wheel and a preparation method thereof, and belongs 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, high ela...

Problems solved by technology

We know that the proportion of diamond abrasives involved in the grinding function of resin grinding wheels is only about 10% so far. Most diamonds fall off prematurely due to their poor bonding force, heat during the grinding process, or the influence of external forces. Thus greatly restricting the service efficiency and life of the resin grinding wheel
