The quality inspection of grinding discs can be carried out from the following aspects:
1. Shape and size inspection, checking whether the geometric shape, inner diameter, outer diameter, thickness and other parameters of the grinding disc meet the requirements;
2. Hardness testing, testing whether the hardness of the grinding disc meets the requirements. Workpieces with different hardness requirements need to use grinding discs with different hardness;
3. Smoothness detection: The surface flatness of the grinding disc has an impact on the processing quality and needs to be tested;
4. Quality sampling inspection: For grinding discs produced in large quantities, sampling inspection is required to check their fragmentation, wear, balance, and whether the installation holes are qualified;
5. Other special tests, such as radiation testing, are required for specific industries and applications of grinding discs.
