Trouble shooting (Diamond wheels)

Rollover: lopsided radius over the glass edge

Check the alignmen of the glass horizontal plane to the center of the groove profile.

Maintain the horizontal motion of the AL2O3 stick while dressing.

Check the profile of the wheel.

Check the horizontal alignment of the grinding table and/or grinding arm

Low grinding speed

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

Check the coolant system.

Dress with an AL2O3 stick.

Check the rpm of the wheel so as the maintain a peripheral speed of 45-50 m/s.

In some cases, the motor hp may be insufficient for the required material removal rate.

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

Low life between retrue

Check for excessive material removal rate by controlling the cut size and the grinding speed.

Check the coolant system.

Make sure that the frequency of dressing has not increased, and the grit size of the AL2O3 stick is of the same size or one size finer than the diamond mesh size.

If life is still low, consider modifying the groove to a more shallow profile.

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

Longer break in time

Check if the wheel mounting procedure and the star-up procedure are followed.

Compare the break in time of a new wheel against that of a retrued wheel. If the retrued wheel has a longer break in time, check the type of the silicon carbide wheel used by the retruer.

If the new wheel takes a longer time to break in , check with the wheel manufacturer for the appropriateness of the profiling process.
