Reason: CBN grinding wheels have high hardness and density, which are different from ordinary grinding wheels in terms of weight distribution and rotation characteristics; The clearance between the old machine tool spindle is more pronounced when it is too large.
Performance: Straight ripples and vibration patterns appear on the surface of the workpiece, and the machine tool has a low-frequency buzzing sound.

1. Vibration pattern, ripple spindle clearance, weight mismatch reduce feed, check spindle, rebalance.
2. Insufficient cooling for grinding burns, excessive cutting force, increased cutting fluid, and reduced single cut depth.
3. The surface is rough, the grinding wheel is not sharpened, the speed is low, the grinding wheel is refined, and the grinding wheel line speed is increased.
4. The size drift machine tool runs empty before thermal stability, and temperature compensation is done before batch production.
5. Poor sand blocking and debris removal, poor repair, strengthened flushing, and optimized repair parameters.
