Grinding discs can be classified based on material, purpose, and shape:
1. Sandwheel: made of materials such as sandstone, diamond, and silicon carbide, mainly used for cutting and grinding metals and stones.
2. Sandcloth disc: Sandcloth or other soft materials cover the grinding disc, used for grinding and polishing metal and non-metal materials.
3. Cutting disc: used for precise cutting on metal, with sharp edges and high-speed rotation characteristics.
4. Stone grinding disc: used for grinding and polishing stone, usually made of hard materials such as ceramics and diamonds.
5. Grinding wheel: Similar to sand wheel, but grinding wheel can perform finer grinding and polishing, used for processing delicate materials such as glass and ceramics.
6. Polishing disc: used for polishing metal and non-metal materials with high smoothness.
7. Drill bit disc: specifically designed for cutting metal materials with strong toughness and hardness.
8. Wire reel: used for grinding and polishing metal wires.
