Should be noted when grinding 1. Before grinding, first determine the correct bearing model, and identify the drawings to clarify the processing technical requirements between the parts. 2. Before driving, you must carefully check whether the operating handles or buttons are in the correct position, and whether the various movements of the grinding machine are normal. 3. Before using the new cutting disc, you must first idle for 5 minutes. After confirming that the operation is normal, first trim the outer and both ends of the resin EN12413 cutting discs, then remove it together with the flange, and then perform a static balance. 4. Before grinding, carefully check whether the workpiece being clamped is correct and the fastening is reliable. In particular, pay attention to adjust the position of the stopper and tighten it. Take care to prevent the cutting disc from colliding with the support frame, chuck or tip holder. 5. During the operation of the cutting disc, the operator should not stand in the direction of the front of the cutting disc and should not lean on the grinding machine to avoid accidents. 6. When grinding, first rotate the cutting disc and the workpiece, and slowly bring the cutting disc close to the workpiece until it is slightly in contact with the workpiece; and then feed the workpiece and the cutting disc under normal operating conditions (the feed must not be too strong) Also, you must stop after you retreat. 7. The workpiece cannot be measured while it is still running. Do not touch the cutting disc with your hand or wipe the rotating workpiece with cotton sand. 8. The operator should wear a fitted overalls and wear a mask to avoid inhaling dust and grinding liquid mist beads; women workers should wear a working cap; when trimming the flat abrasive cutting disc, pay attention to protect the glasses to prevent debris from flying into the eyes. 9. Before stopping the vehicle, cut off the grinding fluid supply system and let the cutting disc idle for 2 minutes to remove the grinding fluid adsorbed in the cutting disc. Grinding refers to the processing method of using abrasives and abrasive tools to remove excess material on the workpiece. It belongs to the finishing industry and is widely used in the machinery manufacturing industry.
