What problems do the double-face grinding wheel encounter during the grinding process? How do we deal with it?

       First, the CBN grinding wheel burns the workpiece during the grinding process

       1. The hardness of the CBN grinding wheel is selected to be high: the grinding wheel with the appropriate hardness should be replaced.

       2. The nozzle direction of the coolant is not correct or the flow rate is insufficient: the nozzle direction of the coolant is adjusted and the flow rate is increased.

       3. CBN wheel dressing is not enough: replace the CBN wheel dresser and re-grind the wheel.

       4. The feed amount for workpiece grinding is too large: the feed amount is appropriately reduced.

       5. The filter in the coolant is not clean: recheck the adjustment cooling system.

 Second, the grinding workpiece size is relatively poor

       1. The hardness of the selected grinding wheel is too large: replace the grinding wheel of appropriate hardness.

Third, the surface of the CBN grinding wheel appears

       1. The feed is too large: reduce the feed.

       2. The grinding wheel is hard: reduce the hardness, increase the workpiece speed and speed up the dressing.

       3. The grinding wheel is not flattened: the grinding wheel is re-trimmed. The vibration of the machine tool is checked: the vibration of the machine tool and the surrounding environment is checked.

  Fourth, the consistency of the total workpiece size is relatively poor

       1. The hardness of the selected grinding wheel is too low: replace the grinding wheel with the appropriate hardness. Long-life face grinding resin CBN grinding wheel

       5. The surface roughness of the workpiece after grinding is relatively poor.

       1. The workpiece is too slow: speed up the workpiece.

       2. The coolant is not fully filtered: Check that the filter system that adjusts the coolant is normal.

       3. The feed rate is too large: the feed rate is appropriately slowed down.

       4. The grinding wheel speed is too low: adjust the rotation speed of the grinding wheel.

       5. Grinding wheel is not in place: adjust or replace the CBN wheel dresser to re-trim.

       6. The selected grinding wheel particle size is not matched: replace the matching grinding wheel.
