Description

Technical Field

[0001] The utility model relates to the technical field of grinding, in particular to a grinding disc which is convenient to clamp. Background Art

[0002] In industrial manufacturing, grinders are often used to grind the surface of steel. The grinding disc can remove defects, burrs, oxide layers, etc. on the surface of the workpiece through high-speed rotation and friction, making the surface smoother and flatter. The grinding surface is the core part of the grinding disc, usually made of high-hardness, wear-resistant materials such as ceramics and diamonds. The substrate is responsible for supporting the grinding surface, usually made of metal materials such as steel and aluminum alloy. The connecting part is used to connect the grinding disc to the grinder to ensure the stability and reliability of the grinding process.

[0003] Grinding discs will wear out after long-term use and need to be replaced frequently. Traditional grinding discs are usually connected by bolts and threads, which are troublesome to install and disassemble. Specific tools are required, and the replacement speed is slow and inconvenient to use, which can easily affect the grinding efficiency and processing progress.
