Characteristics of abrasive tools
1. Abrasive tools are tools used to grind, polish and trim the surface of the workpiece.
2. Abrasive tool is a tool with abrasive particles, used to remove impurities and unevenness on the surface of the workpiece.
3. The grinding tool can complete the grinding work by rotation, vibration or other motion.
4. The grinding tool can choose different abrasive materials according to different grinding needs, such as grinding wheel, sand belt, sandpaper, etc.
5. Grinding tools can be manually operated or mechanical equipment can be used for grinding work.
6. The choice of abrasive tools depends on the workpiece material, shape and required surface quality.
7. Abrasive tools can be used for grinding various materials such as metal, ceramics, glass and so on.
8. The use of abrasive tools requires attention to safety matters, such as wearing protective glasses, gloves and masks.
9. The maintenance and maintenance of abrasive tools can extend their service life, such as regular cleaning and replacement of abrasive particles.
10. The precision and efficiency of the grinding tool have a very important impact on the surface quality of the workpiece, so it is very important to choose the right grinding tool.
