What grinding problems will centerless grinder encounter in the process of grinding?

The grinding problems of centerless grinder are as follows:
1. The workpiece roundness of centerless grinder is out of tolerance and the grinding wheel is not sharp. The characteristics of the workpiece and the rule of accuracy change should be mastered and the grinding wheel should be trimmed in time.
2. The roundness of the workpiece of the centerless grinder is out of tolerance, the guide wheel is not rounded, or it is out of round due to too long working time. Pay attention to timely repair.
3. The workpiece of the centerless grinder is angular and round, and the imbalance between the grinding wheel and the guide wheel is too large. Re balance the grinding wheel and the guide wheel.
4. Workpiece straightness of centerless grinder is out of tolerance, and the grinding wheel is too soft during cut in grinding. Select a harder grinding wheel, pay attention to timely dressing, reduce cut in feed, and increase the number of smooth grinding.
5. If the cylindricity of the workpiece of the centerless grinder is out of tolerance, the position of the dresser shall be adjusted according to the taper direction of the workpiece, and the grinding wheel shall be trimmed again.
6. The cylindricity of the workpiece of the centerless grinder is out of tolerance, and the hardness of the grinding wheel is too low during cut in grinding. Select a harder grinding wheel, pay attention to timely dressing, reduce the cut in feed, and increase the number of smooth grinding.
