Wheel Dressing - Grizzly T27400 Owner's Manual

Wheel Dressing

With use, the surface of the grinding wheel will fill
with metal residue and grit. When this happens,
the wheel needs to be cleaned or "dressed."
The goal of dressing the wheel is to remove the
contaminants and make the grinding surface
even and flat to ensure good grinding results.
A diamond dressing tool or "dresser" has been
included with the T27400 for this purpose.
Tools Needed
Hex Wrench 8mm .............................................. 1
Hex Wrench 2.5mm ........................................... 1
To use the included diamond dresser:
1. DISCONNECT LATHE AND GRINDER
FROM POWER!
2. Using a workpiece or a section of bar stock
as a stationary mounting location, clamp the
tool holder so the dresser is perpendicular to
the grinding surface of the wheel (see Figure
9).
Note: The included diamond dresser may
need to be cut to the appropriate length to fit
your specific lathe.

Grinding wheels can quickly remove a lot of
skin. Make sure the dresser and tool holder
are firmly secured in place, and keep your
hands a safe distance away from grinding
wheel during operation.
3. Secure the dresser into the tool holder by
tightening the set screw on tool holder.
4.
Ensure tip of dresser is at or below the grind-
ing wheel centerline (see Figure 10). Adjust
tool post grinder elevation as needed (see
Adjusting Grinder Spindle Centerline on
Page 15).

centerline of grinding wheel.
5.
Position grinding wheel so dresser is to one
side of wheel surface and slightly touching it.
6. Connect grinder to power and turn it ON, then
slowly move wheel back-and-forth across
dresser, making multiple light passes until
you are satisfied with wheel surface condi-
tion.
Note: Several light passes across the dress-
er will produce the best results, with the least
amount of wear to the wheel or dresser.
