Why add ordinary abrasives to superhard grinding wheels?

In the manufacturing process of super-hard grinding wheels, ordinary abrasives are sometimes needed because ordinary abrasives can regulate the performance of super-hard grinding wheels. This regulation is not only reflected in the improvement of grinding efficiency and finish, but also in the comprehensive optimization of the self-sharpening, wear resistance and adaptability of the grinding wheel. Super-hard grinding wheels occupy an important position in the field of efficient grinding with their excellent hardness and wear resistance. However, in the face of diverse processing requirements and complex workpiece materials, it is often difficult to achieve the best grinding effect with super-hard abrasives alone. At this time, the addition of ordinary abrasives is particularly important. They are like a "seasoning" and play an indispensable regulating role in super-hard grinding wheels, so that the grinding wheels can maintain efficient grinding while taking into account good surface quality and long service life. Next, this article will explore the specific role of ordinary abrasives on super-hard abrasives from multiple aspects and analyze their importance in the grinding process.

1. Improve grinding efficiency and finish

1.1 Synergistic effect improves grinding efficiency

Superhard abrasives show extremely high efficiency in the grinding process due to their high hardness and high wear resistance. However, in some cases, such as when processing soft materials or workpieces that require fine grinding, the single use of superhard abrasives may cause excessive wear or excessive grinding force, affecting grinding efficiency. At this time, adding an appropriate amount of ordinary abrasives can form a synergistic effect. Ordinary abrasives, with their lower hardness and better cutting performance, assist superhard abrasives in cutting, effectively reduce grinding resistance, and improve grinding efficiency.

 

1.2 Optimize finish

The delicate grinding action of ordinary abrasives helps to obtain a more uniform grinding surface and reduce scratches and burns. Adding an appropriate amount of ordinary abrasives to the superhard grinding wheel can balance the cutting force and thermal effect during the grinding process, making the grinding surface smoother and meeting the needs of high-precision processing.

 

2. Enhance the self-sharpening and wear resistance of the grinding wheel

2.1 Improve self-sharpening

The self-sharpening of the grinding wheel refers to its ability to automatically maintain a sharp state during the grinding process. Although superhard abrasives have high hardness, they may also become passivated after long-term grinding. The addition of ordinary abrasives, due to their relatively low hardness, is more likely to be worn and fall off during the grinding process, thereby exposing a new grinding surface and improving the self-sharpening of the grinding wheel. This improvement in self-sharpening helps to maintain the sharp state of the grinding wheel and extend the service life of the grinding wheel.

 

2.2 Enhance wear resistance

The appropriate amount of ordinary abrasives can also balance the grinding force generated by superhard abrasives to a certain extent and reduce the wear of the grinding wheel. The addition of ordinary abrasives makes the grinding force distribution during the grinding process more uniform, avoids local excessive wear, and thus enhances the wear resistance of the grinding wheel.

 

3. Optimizing grinding parameters and adaptability

3.1 Flexibility of grinding parameters

The addition of ordinary abrasives makes superhard grinding wheels more flexible in grinding parameters. By adjusting the type, particle size and amount of ordinary abrasives, the grinding force, grinding temperature and workpiece surface quality can be precisely controlled. This flexibility enables superhard grinding wheels to adapt more widely to different types of workpiece materials and processing requirements.

 

3.2 Adapting to diversified processing needs

Faced with diverse processing requirements and complex workpiece materials, superhard grinding wheels often find it difficult to achieve the best grinding effect with superhard abrasives alone. The addition of ordinary abrasives is like adding a "panacea" to the grinding wheel, allowing the grinding wheel to flexibly respond to various processing challenges and meet diverse processing needs.

 

4. Balance between economy and environmental protection

4.1 Reduce manufacturing costs

Although superhard abrasives have excellent performance, their costs are relatively high. By adding an appropriate amount of ordinary abrasives, manufacturing costs can be reduced while ensuring the grinding effect. This improvement in economy helps companies reduce production costs and improve market competitiveness.

 

4.2 Environmental considerations

Ordinary abrasives are usually easier to recycle and process, which helps reduce waste generated during the grinding process. This is not only in line with the concept of sustainable development, but also helps reduce the company's environmental costs and social responsibility.

 

Conclusion

In summary, the addition of common abrasives to super-hard grinding wheels has a significant effect on improving grinding efficiency, finish, and enhancing the self-sharpening, wear resistance, and adaptability of the grinding wheel. At the same time, this addition also helps to balance economic efficiency and environmental protection, so that super-hard grinding wheels can show more outstanding comprehensive performance in the face of diverse processing requirements and complex workpiece materials. Therefore, when designing and manufacturing super-hard grinding wheels, factors such as the type, particle size, and addition amount of common abrasives should be fully considered to achieve the best grinding effect and economic benefits.
