In the process of using the diamond
[u]grinding wheel made in China[/u], some problems will be encountered. When these problems are encountered, the diamond grinding wheel must be replaced, and it is impossible to make a great loss due to the convenience of the moment.
First, the problem of wear: any grinding wheel made in China has its own wear requirements. If the wear 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.
Second, the validity period: the new grinding wheel made in China that is taken out of the warehouse is not necessarily a qualified grinding wheel. Even the new grinding wheel bought from the manufacturer is not necessarily a qualified grinding wheel. Any grinding wheel has a certain expiration date and is used within the effective 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 made in China must be subjected to the rotation test after one year of storage. Only qualified persons can use it”. Third, the texture problem: In the process of use, if it is found that the grinding wheel appears locally cracked, it should be stopped immediately, and the new grinding wheel should be replaced again to avoid causing the grinding wheel to break and hurt people.
The grinding wheel made in China must meet all the specifications to be used. If it is found to be non-compliant, it must be replaced in time to ensure the accuracy of the worn material and the safety of the operator.
