Application Problems and Treatment Methods of Grinding Wheel with Double Face Grinding

What are the problems with the grinding process of the double face grinder in the grinding process? How should we deal with it?

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

1. CBN grinding wheel hardness selected high: should replace the appropriate hardness of the wheel.

2. The nozzle of the coolant is not oriented or the flow is not sufficient: the nozzle direction of the coolant is adjusted and the flow rate is adjusted.

3.CBN wheel dressing is not sufficient: replace the CBN wheel dresser re-grinding wheel dressing.

4. Feed the workpiece grinding too large: appropriate to reduce the feed.

5. The filter is not clean in the coolant: re-check the adjustment of the cooling system.

Second, the grinding workpiece size intermittent relatively poor

1. Select the wheel hardness is too large: the replacement of the appropriate hardness of the wheel.

Third, CBN wheel surface appears shock pattern

1. Feed too much: reduce the feedrate.

2. Reducer wheel: reduce the hardness, improve the workpiece speed, speed up the dressing.

3. Grinding wheel no leveling: the wheel re-dressing machine vibration: check the machine and the surrounding environment vibration.

Fourth, the overall size of the workpiece is relatively poor

1. Select the wheel hardness is too low: the replacement of the appropriate hardness of the grinding wheel. Long life end grinding resin CBN wheel

5, after grinding the workpiece surface roughness is relatively poor

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

2. The coolant is not filtered adequately: Check that the filter system for the coolant is normal.

3. Feeding is too large: the appropriate slow feed rate.

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

5. Wheel dressing is not in place: adjust or replace the CBN wheel dresser re-dressing.

6. Selection of the wheel size is not matched: the replacement of the matching size of the wheel.
