Abstract

The invention discloses a CBN (cubic boron nitride) resin grinding wheel and a preparation method of the CBN resin grinding wheel. The CBN resin grinding wheel is prepared from the following components in parts by weight, 50-60 parts of CBN grinding material, 5-10 parts of white corundum grinding material, 5-10 parts of silicon carbide powder, 5-15 parts of phenolic resin powder, 2-6 parts of phenolic resin liquid, 1-2 parts of n-butyl methacrylate, 5-10 parts of nano dolomite dust, 5-10 parts of nano quartz sand powder, 2-5 parts of micro polyamide wax mist and 2-5 parts of steel scrap powder. According to the CBN resin grinding wheel and the preparation method of the CBN resin grinding wheel, as a 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, and cracks formed by rigid grinding are reduced, thereby the use efficiency and service life of the resin grinding wheel are improved further; and in addition, as steel power is added, fast heat dissipation effect is achieved, a great deal of heat generated in a cutting process of the grinding wheel can be dissipated quickly, and the effect of lowering cutting temperature is achieved.

Description

technical field [0001] The invention relates to a CBN 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 elastic...
