105 * 1.2 * 16 cutting disc and other cutting pieces, like the grinding wheel of 115 * 1 * 22 cutting disc, the grinding wheel piece should have some precautions in the replacement process, then what are these matters? I will give you a summary today.
The grinding wheel of the cutting piece is the main accessory for the grinding of the grinding wheel. It has a great loss in the work, so the following matters should be noted during the replacement of the grinding wheel:
Wear problems Any wheel 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.
Validity issues The new grinding wheel that is brought out of 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;
Exceeding 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”.
