Resin binder has higher bonding strength than ceramic binder, and the mechanical strength of abrasive tools is higher than that of ceramic abrasive tools. Can be used at a high speed, can withstand a large grinding pressure, operation is relatively safe, so it is widely used in steel, automotive bearings, chemical machinery, construction and other industries rough grinding process.
2.It has a certain elasticity
The resin belongs to the high polymer compound, has the certain toughness and the elasticity, can buffer the grinding pressure, therefore the grinding effect is good, has the good polishing function, can improve the workpiece surface processing quality.
With the emergence of new resin, it can be made into various strength and performance of resin grinding tools, can be used for grinding, rough grinding, cutting, semi-precision grinding, fine grinding, polishing and other grinding tools.
4.Can be made into a variety of special shape requirements of the grinder
The resin binder has low hardening temperature and low shrinkage, and can be made into a variety of complex shapes and special requirements. Such as a cymbal wheel, with mesh cloth high-speed cutting pieces.
5.Low heat resistance, not easy to burn
The resin binder has low heat resistance, and it is easy to be carbonized when heated in grinding process, which makes the dull abrasive particles fall off automatically, exposing the new sharp abrasive particles, reducing the heat in the grinding area, and avoiding the workpiece burns. Therefore, it is suitable for surface grinding, but the abrasion is greater than that of ceramic grinding tools.
6.Short production cycle
The production cycle of resin abrasive tools is short, the equipment is simple, the investment is little, the capital turnover is fast, the production efficiency is high, is advantageous to the specialized production.
7.Poor chemical stability
General resin abrasive resistance and water resistance is poor, can not be stored for a long time. In the case of alkali, the resin structure degrades, affecting the strength and hardness of the abrasive tool.
In addition, the resin grinding tool price is high, the production environment is poor.
