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 will not be 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 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 results. For best results and safe use, the
dressing tool must be positioned in the trailing
zone of the wheel, as shown in Figure 37. 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 injury or property damage.
Figure 38. Dressing tool setup.
To dress the grinding wheel:
1. Insert the diamond-tipped dressing tool into
its base (see Figure 38), and use a 4mm hex
wrench to tighten the locking set screw.
2. Lower the headstock so the wheel is
approximately 5mm lower than the tip of the
dressing tool.
3. Position the tip of the dressing tool at the
trailing side of the wheel, as shown in
Figure 37, and move the table inward until
the diamond tip slightly touches the edge of
the grinding wheel. Verify by rotating the
wheel by hand and listening for contact.
4. Apply the magnetic chuck, and move the
cross slide so the diamond tip is free of the
grinding wheel.
5. Start the grinder, and use the cross slide
handwheel to progressively move the table
so the diamond sweeps across the wheel at a
depth between 0.01 – 0.03mm.
