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

1. 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 can not 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 dust proof, keep the unused grinding wheel clean, and do not press it.

4. When installing the 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 grinding wheel, for safety reasons, please do not install the qualified protective cover before starting the machine.

Due to objective technical reasons, most of the domestic and foreign countries use traditional knife bowls for turning. In the process of processing it, 4.5 inches grinding wheel drives the quenched 45th steel thin-walled knife bowl to rotate at a higher linear velocity (300-400 m/min), and carries the cutter to remove the excess amount of the grinding wheel. 

Due to the high-speed rotation of the processed 4.5 inches grinding wheel and the knife bowl, the dust and noise in the processing are large, the cutting depth and the feed amount are small, so the processing efficiency is low and the comprehensive cost is high, and the operator is labor intensive.

If a large-grain diamond cutter is used, it is expensive, and because the diamond has low bending strength, it is easily damaged during cutting, and the cutting depth and the feed amount when cutting the 4.5 inches grinding wheel are small, and it is generally used only in finishing.
