Darex XPS-16 Operating Instructions - Manual (Page 57)

57
The Darex XPS-16 comes equipped with electro-
plated,
180 Grit CBN (Cubic Boron Nitride) and
220 Grit diamond grinding wheels. The CBN
wheel, ready to sharpen HSS and Cobalt drills has
been calibrated to your sharpener. The diamond
grinding wheel, for grinding carbide drills, has a
honing brush mounted to it. You will find both the
diamond and CBN wheel packaged in the tool kit.
Sharpening with an electroplated CBN (Cubic Bo-
ron Nitride) or diamond grinding wheel reduces
grinding cost and improves quality of the finished
product. These results are obtained because the
grinding material is super abrasive. The CBN is
second only to diamond in hardness. In fact, CBN
has twice the hardness and four times the abra-
sion resistance of an aluminum oxide grinding
wheel. The CBN and diamond wheel last longer;
the grinding process is faster and less grinding
time is lost due to wheel breakdown & mainte-
nance.
WHEEL MAINTENANCE
These wheels are maintenance free from truing
and dressing but will need to be cleaned periodi-
cally. After removing the wheel from the
sharpener, saturate the wheel with any type of
oil-less solvent, such as Automotive Brake
Cleaner. It is helpful to use a soft bristle brush
and lightly brush the saturated wheel loosening
the impacted grinding particles. Re-saturate the
wheel to flush out any loosened debris.
NOTE: If after cleaning wheel, the drills still
discolor or burn, the wheel life may be ex-
hausted and the wheel will need to be re-
placed.

INSTRUCTION FOR USE OF
CREPE STICK
TO CLEAN GRINDING WHEEL
The CREPE STICK (PP0001981), included in the
tool kit can be used to clean the grinding wheel
while on the machine. This procedure provides a
convenient method that can be applied about
once per hour. A more thorough wheel cleaning
should be preformed at regular intervals as de-
scribed in the user manual.
1. Be sure the machine in the home position.
2. The grinding wheel must be rotating.
3. Lightly press a corner of the crepe stick
against the surface of the grind wheel.
4. Sweep it across the face of the wheel.
5. Repeat several times.
Caution: Wear Eye protection and firmly
grip the crepe stick while performing this
procedure.
