Relevant Data Of Abrasive Tools
Organic characteristics
Organic abrasive tools are characterized by wide range of use, certain elasticity, high bonding strength and good polishing performance. It has been applied in rough, fine, fine, polishing and other grinding processes, and its resin abrasive tool has the following characteristics:
1. High bonding strength
Compared with the ceramic bond, the resin bond has a high bonding strength. The grinding speed of the resin wheel can reach 80~120 m/s, and it can withstand large grinding pressure. Grinding pressure of heavy-loaded grinding wheel is up to 10 × 104~40 × 104N, widely used in iron and steel industry, such as various ingots, billets and other rough grinding processes. Rough grinding, such as high-speed heavy-duty special grinding wheel, is safe to operate, suitable for high-speed grinding and high-feed grinding, with high grinding efficiency.
2. With certain elasticity
Compared with ceramic abrasive tools, resin abrasive tools have good toughness, plasticity and ductility. Its elastic modulus (E) is dozens of times lower than that of ceramics. Therefore, resin abrasive tools are suitable for preparing various kinds of thin plate grinding wheels and high-speed cutting grinding wheels. At the same time, due to certain elastic deformation, the grinding force can be buffered. Therefore, the grinding effect is good, the polishing effect is available, and the roughness of the machined surface can be improved.
3. Able to make abrasive tools with various complex shapes and special requirements
Due to the low hardening temperature of resin-bonded abrasive tools, they can be hardened at room temperature and have a small shrinkage rate, and can be made into abrasive tools with various complex shapes and special requirements. For example, glass fiber reinforced resin grinding wheel, porous resin grinding wheel and grooved grinding wheel with easy chip removal and good heat dissipation are used; Bolt fastening grinding wheel, electrolytic grinding wheel and polishing grinding wheel to improve grinding process conditions; And cylindrical, bowl-shaped and butterfly shaped grinding wheels.
4. Wide application range
Because of the variety of new resin bond, it can be made into resin abrasive tools with various strength and performance. Therefore, it can be widely used in rough grinding, rough grinding, cutting, semi-fine grinding, fine grinding, polishing and other processes. Resin abrasive tools have high bonding strength, high use speed, impact resistance, and are suitable for rough grinding and rough grinding; Resin abrasives have good toughness and are suitable for cutting process; Resin abrasive tools have good elasticity and certain polishing properties, and can be used for fine grinding and polishing. Resin abrasives have low heat resistance and are easy to wear, and are suitable for surface grinding and finishing.
5. Helps to prevent burns from the workpiece being ground
The resin bond has low heat resistance, which can reduce or avoid burning the workpiece. The heat generated in the grinding process of the workpiece first causes the resin to carbonize, causing the passivated abrasive to fall off automatically, exposing new sharp abrasive particles, reducing the heat in the grinding area, and avoiding the burn of the workpiece.
6. Resin abrasives have low hardening temperature, short production cycle and simple equipment
