1. The uses of polishing wheels and grinding wheels are different
Polishing wheels are mainly used to polish the surfaces of metals, wood, and other materials to make their surfaces smoother and glossier. Grinding wheels are primarily used in the cutting, grinding, and finishing of metals, stones, glass, ceramics, and other materials.
2. Materials
Polishing wheels are generally made of natural or synthetic velvet, wool, and other fiber materials, and different particles of abrasive materials are added to the inside for manufacturing. Grinding wheels mainly use wear-resistant materials such as aluminum oxide, silicon carbide, and diamonds, and the internal composition and density are also very tight.
3. Manufacturing process
The manufacturing process of polishing wheels is relatively simple, mainly selecting different velvet, wool, and other fiber materials, adding different particles of abrasive materials as needed, and then making them through heating, pressing, drying, and other processes. Grinding wheels require multiple mixing, processing, drying and other complex processes to be made.
4. Effect after processing
Because the velvet, wool, and other fiber materials of the polishing wheel have good softness, and the abrasive material particles added inside are relatively small, the polishing wheel can grind and polish the material more carefully to achieve a smoother and glossier effect. The grinding wheel has a relatively rough processing effect due to its high hardness, but it can quickly cut and grind materials to improve processing efficiency.
In summary, although the polishing wheel and the grinding wheel are similar in appearance, they are different in use, materials, manufacturing process, processing effect, etc. In actual processing operations, the appropriate grinding wheel and polishing wheel should be selected according to the processing materials and processing procedures to achieve the best processing effect.
