Wheel Dressing
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 sleeve and flange.
IMPORTANT: Balance wheel, as instructed on Page 27, before dressing it.
Dressing the wheel correctly will save you from wasting grinding abrasive and shattering the dressing tool diamond. Additionally, with a prop- erly 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; or a slow dress- ing 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. For best results and safe use, the dress- ing tool must be positioned in the trailing zone of the wheel, as shown in Figure 38. 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 to the operator or bystanders.
