The main factors affecting the grinding performance of coated grinding tools are the three elements of coated grinding tools and their combination forms. In terms of raw materials, the substrate, abrasive, and binder used in the production of coated grinding tools largely determine the performance of coated grinding tool products. In order to adapt to the development trend of efficient, precise, and heavy-duty polishing of coated grinding tools, the types of substrates, abrasives, and binders used in the production of coated grinding tools are becoming increasingly diverse and their performance is constantly improving.
The use of new substrates such as latex paper, polyester film, sponge, and non-woven fabric greatly improves the flatness and flexibility of coated grinding tools;
The application of new abrasives such as calcined corundum, semi brittle corundum, and zirconia corundum further improves the cutting efficiency and polishing effect of coated abrasives;
The use of modified phenolic resin, water-based environmentally friendly epoxy resin, amino resin and other binders has improved the strength and service life of coated grinding tools.
The grinding performance of coated grinding tools is a comprehensive reflection of the combination of three elements. Any improvement in raw material performance and optimization of combination methods can bring about an improvement in the performance of coated grinding tools. The technological research and development of coated grinding tools is to continuously optimize the technical parameters of the three elements, improve the combination of the three elements, in order to improve the grinding efficiency, accuracy, effectiveness, and extend the service life of coated grinding tools.
