Common Problems in Using Superabrasive Abrasives

The surface roughness of the processed product does not meet the requirements

1. Inappropriate selection of abrasive particle size.

2. The hardness of the grinding wheel is too low or the organization is too loose, and the abrasive particles fall off too quickly.

1. Choose a grinding wheel with fine particle size.

2. Adjust the grinding wheel formula to improve the hardness of the grinding wheel.

There are burns or vibration marks on the surface of the workpiece

1. The rigidity of the machine tool is not good, and the rigidity of the spindle is not good.

2. The grinding wheel is not fully edged.

3. The organization of the grinding wheel is too tight, and the grinding resistance is too large without the chip space.

4. Too much cutting edge during grinding.

1. Check whether the performance of each part of the machine tool and the tightness of the fit are appropriate, and enhance the rigidity of the spindle.

2. The grinding wheel should be fully edged, and the abrasive particles should be exposed to the binder.

3. Select the grinding wheel with suitable binder and adjust the hardness of the grinding wheel.

4. Adjust the grinding parameters.

Grinding wheel clogged

1. Too much cutting edge during grinding.

2. Insufficient cooling.

3. Improper selection of grinding fluid.

4. The organization of the grinding wheel is too tight.

1. Adjust the grinding parameters.

2. Increase the amount of cooling.

3. Resin bond type grinding wheel, do not use emulsified oil type grinding fluid.

4. Look for a grinding wheel with a looser tissue density.
