The problems that should be paid attention to when using the 4.5 inches grinding wheel

The problems that should be paid attention to when using the 4.5 inches grinding wheel:

1. Resin grinding wheel should be inspected before installing the fan to see if there is any crack and use a wooden hammer to strike the grinding wheel to hear if there is abnormal sound. If there is, the cooling fan cannot be used, so as to avoid the damage caused by the grinding wheel.
2. For new or alternate use of resin 4.5 inches grinding wheel, it should be idle for more than one minute before use. If everything is normal, it can be used according to the safety regulations of grinding machinery.
3. Since the resin grinding wheel is brittle and fragile, please do not let it be impacted, collided, or fall. Store it with anti-freeze and moisture-proof. Keep the room cool and ventilated, place it flat, stack it neatly, pay attention to dustproof, keep the unused grinding wheel clean, and do not press it.
4. When installing the resin grinding wheel, the center of the resin 4.5 inches grinding wheel must be found. At the same time, the flange should be fastened. After installing the flange, the outer circle of the grinding wheel should be checked whether it is concentric with the main shaft. The resin grinding wheel has at least one side perpendicular to the center line of the main shaft.
5. After installing the resin grinding wheel, for safety reasons, please do not install the qualified protective cover before starting the machine.
