Trouble shooting (Diamond wheels) Burns: on the surface of the ground glass

1.Check the coolant system.

2.Check for excessive material removal rate by:

-controlling the cut size to a maximum of 0.5mm per side,

-maintaining the grinding speed at its recommended limit.

3. If burns still exist, consider modifying the shape of the diamond groove to a more shallow profile.

4. If no effect, consult with the wheel manufacture for diamond-bond matrix hardness for the specific application.

Shiners: unground sections at irregular intervals on the surface of the ground glass.

1.Check the glass positioning on the table with respect to the wheel path.

2.Check for undersized cut at the cutting station.

3.Maintain the specified grinding speed.

4.If condition still exist, dress with AI2O3 stick.

5.If no effect, consult with the wheel manufacture for correct diamond-bond matrix for the specific application.

Oversize: the ground glass is oversized

1.Check the cut size at the cutting station to a maximum of 0.5mm per side.

2.Maintain the specified grinding speed.

3.Check the coolant system.

4.Dress with an AL2O3 stick.

5.If no effect, consult with the wheel manufacture for correct diamond-bond matrix for the specific application.
