Trouble shooting Diamond wheels

Certain common problems encountered during grinding auto glass and their solution checklist are enumerated below:

Chips : small chips on the edge of the glass

If the number of lin.mts of glass ground is close to the average life of the wheel between reture , replace with a new wheel.

If not, dress with an AL2O3 stick.

Ascertain that the wheel T.IR. is within 0.002ⁿ.If it is within the tolerance range, check for the adapter plate runout to be within 0.001''.

Check coolant system to ascertain the following:

-the coolant holes are not clogged.

-the coolant spouts are directed towards the center of the diamond groove.

-the coolant concentration is within the specified limits.

-the coolant is free from bubbles, and

-the coolant dose not have a high dispersion of glass fines.

5. Check if the grinding speed is not higher than recommended.

6. If no effect, consult with the wheel manufacture for correct diamond-matrix for the specific application .i.e. mesh size is not too coarse, and matrix hardness is not too high.
