Why is it necessary to pay special attention to the direction of the nuts rotation when changing the grinding wheel on a metallographic cutting machine?

In the process of replacing the grinding wheel of the metallographic cutting machine, the rotation direction of the nut is very critical. This is because our nut is designed with a left-hand thread, which is different from the common right-hand thread.
If the rotation direction is not noted during the installation or removal process, it may result in the grinding wheel not being correctly installed or removed, and may even damage the equipment. Therefore, we specifically emphasize this point of attention in the steps for replacing the grinding wheel to ensure that users can replace the grinding wheel correctly and safely. This is also a reflection of Chung-Tse's responsibility for product quality and user safety.
