Publish Time: 2025-04-22
In terms of processing accuracy, abrasive resin block performs well. It has high dimensional stability and can maintain the accuracy of shape and size during the grinding process, thereby ensuring that the processed workpiece has extremely high dimensional accuracy. This is due to the hard structure formed after the phenolic resin is cured, which provides stable support for the grinding tool, making the grinding process more accurate and controllable.The surface quality advantage is also outstanding. Its good self-sharpening is one of the key factors. The abrasive grains can continuously expose new sharp edges during the grinding process, ensuring the stability and uniformity of the grinding force, so that the surface roughness of the workpiece after grinding is low and the finish is high. Moreover, abrasive resin block has good elasticity, is less sensitive to vibration, impact, and lateral pressure during grinding, can adapt to higher speeds, and reduce surface defects caused by factors such as tool vibration, thereby obtaining high-quality processing surfaces.Heat resistance is also a highlight. During the precision grinding process, a large amount of grinding heat will be generated due to the high-speed friction between the abrasive and the workpiece, and the binder and the workpiece. Phenolic resin has good heat resistance and starts to thermally decompose at about 280℃ in the air. Although the long-term working temperature does not exceed 120℃, the heat resistance of the modified heat-resistant phenolic resin is significantly improved. This enables the phenolic resin abrasive resin block to effectively resist the influence of high temperature during the grinding process, maintain its own stable performance, reduce the processing error caused by thermal deformation, and ensure the smooth progress of the grinding process.In terms of mechanical strength, the phenolic resin abrasive resin block has high hardness and wear resistance. The higher hardness enables it to withstand greater grinding pressure and ensure the stability of the grinding process; while the good wear resistance prolongs the service life of the abrasive tool, reduces the frequency of replacing the abrasive tool, and reduces production costs.In addition, the phenolic resin abrasive resin block also has good processing performance. It is suitable for cold pressing and semi-hot pressing processes, is easy to mold, and can produce abrasive tools of various shapes and sizes according to different processing requirements. At the same time, it has the characteristics of low odor, concentrated fineness distribution, and good stability, which improves the bonding strength of the product and further guarantees the quality and performance of the abrasive tool.Abrasive resin block has become an indispensable tool in the field of precision grinding due to its advantages of high processing accuracy, good surface quality, strong heat resistance, high mechanical strength and excellent processing performance.
