A centerless grinding machine for grinding the rotating surface of a workpiece usually refers to a centerless cylindrical grinder. On a centerless cylindrical grinder, the workpiece does not need to be centered and supported by the top, but is placed between the grinding wheel and the guide wheel, and is supported by the pallet and the guide wheel.
Next, Run will introduce to you the reasons for the scales and straight white lines on the surface of the centerless grinder.
1. The grinding wheel is unbalanced or blunt, the grinding wheel is too hard, the grain size is too fine, or it is not well trimmed. Carefully balance the grinding wheel, replace the grinding wheel with a softer one and perform dressing, etc.
2. The speed of the guide wheel is too high. Reduce the speed of the guide wheel appropriately.
3. The center of the workpiece is too high, causing jitter. Lower the height of the pallet appropriately.
4. The pallet has insufficient rigidity. Thicken the pallet and tighten it.
