In the process of using the resin grinding wheel, when it reaches a certain level, it needs to be replaced. What problems should be paid attention to when replacing the resin grinding wheel? Mainly from three aspects: wear problem, expiration date, texture problem, below Let us take a look!

Wear problem: Any grinding wheel has its certain wear and tear requirements. If the wear condition reaches a certain level, it must be replaced with a new one. It is not necessary to use excessive wear in order to save materials. This is a very unsafe violation. It is generally stipulated that the new grinding wheel should be replaced when the grinding wheel is worn to a diameter 10 mm larger than the diameter of the chuck.

Validity issue: The new grinding wheel that is taken from the warehouse is not necessarily a qualified grinding wheel. Even the new grinding wheel purchased from the manufacturer is not necessarily a qualified grinding wheel. Any grinding wheel has a certain expiration date and is used within the valid period. It is a qualified grinding wheel; if it is used beyond the expiration date, it is not necessarily a qualified grinding wheel. The regulations stipulate that “the grinding wheel should be used within the validity period. The resin and rubber bond grinding wheel must be subjected to the rotation test after one year of storage. Only qualified persons can use it”.

Texture problem: If there is a local crack in the grinding wheel during use, stop using it immediately and replace the new grinding wheel to avoid causing the grinding wheel to break and hurt people.
