This test will give you an indication of any 

internal damage that may not be obvious during 
a visual inspection.

1.  Make sure the wheel that you test is clean 

and dry; otherwise, you may get false 

results.

2.  Hang the wheel in the air with a piece of 

cord or string looped through the hole in the 

center, as shown in Figure 30.

3.  At the locations shown in Figure 30, gently 

tap the wheel with a light non-metallic 

device such as the handle of a screwdriver or 

a wooden mallet.

An undamaged wheel will emit a clear 

metallic ring or “ping” sound in each of these 

spots. A damaged wheel will respond with 

a dull thud that has no clear tone. If you 

determine from the ring test that the wheel 

is damaged, DO NOT use it!

Superior grinding results can only be achieved 

with a properly balanced and dressed wheel. Do 

not assume that a wheel will run true on the 

spindle if it is new or has not been separated 

from the hub. 

Dressing the wheel correctly will save you from 

wasting grinding abrasive and shattering the 

dressing tool diamond. Additionally, with a 

properly balanced and dressed wheel you can 

rest assured that if you have finish problems, the 

grinding wheel is not the culprit. 

Depending on the finish required, varying 

degrees of roughness can be obtained. For 

example: A fast dressing at a depth of 0.03mm 

will prepare a wheel surface for rough cuts, and 

slow dressing with multiple light passes of the 

diamond at a depth of 0.01mm will prepare the 

same wheel for finish cuts. 

Positioning is critical for the dressing tool so 

you will not shatter the diamond or have poor 

dressing results. The dressing tool must be 

positioned in the trailing zone of the wheel, as 

shown in Figure 31, for best results and safe 

use. If the tool is positioned on the leading side 

of the wheel, the diamond will be shattered or 

even grabbed by the wheel and drawn under the 

grinding wheel, causing severe damage or injury.
