Power Controls
To operate this machine, use the
Rocker Switch (shown above). The
center position designates that the
machine is “OFF”. Press the left side
of the switch to operate in Counter
Clockwise (CCW) mode. Use CCW
mode when you are working on
the left side of the wheel. Press the
right side of the switch to operate
in Clockwise (CW) mode. Use CW
mode when you are working on the
right side of the wheel.
There is an optional Power Foot
Switch (#002-205) available that will
allow you to start the machine with
the touch of your toe. The foot switch
is handy especially when you want
both hands free. The foot switch is
ideal for horizontal lapping.
Changing The Fuse
FIRST: UNPLUG THE MACHINE.
The fuse is located near where the
power cord connects to the machine
(H). Using a screw driver, gently turn
the spring-loaded fuse retainer until
it is loose and pops out. Replace the
fuse in the retainer with the correct
fuse. Press it back into the fuse
housing. Gently turn the retainer with
the screw driver until it locks.
Horizontal Wheel Use
As you learned when you installed
the table, the motor housing pivots so
the wheel is in a horizontal position.
This feature has many diverse uses.
Two of the more common uses
include renishing the tops (or faces)
of inserts and honing at surfaces
on tool blanks. It is also useful in
removing build-up from the top edges
of cutting tools.
Grinding on
Diamond Wheels
Follow this recommended procedure.
Approach the surface carefully with the
tool. Apply cutting pressure smoothly.
Be especially attentive when rst
cutting sharp points. Wet the diamond
surface with the water soluble cutting
uid supplied with your Accu-Finish.
Only occasional spraying to keep the
surface wet is required. Oscillate the
table whenever practical during cutting.
This promotes faster cutting, helps
keep the wheel clean, and increases
wheel life. Clean the diamond wheels
when required (see below).
Clean or Dress a Wheel?
Terminology is often confusing on
the difference between cleaning and
dressing a diamond wheel. Cleaning
means removing dirt. Dressing is
done with an abrasive stick. Dressing
is performed on a rotating wheel and
actually removes a small amount of
wheel material, mostly the bonding
agent. Proper dressing will extend
wheel life, not shorten it. Cleaning
should be done much more regularly
than dressing.
Clean a Diamond Wheel
Remove wheel from machine and
take wheel to a sink. Wet the wheel
with water and liberally sprinkle with
scouring powder (e.g. Bon Ami, Ajax,
Comet). IMPORTANT: DO NOT USE
SOLVENTS. With a scrub brush or rag,
work the powder into the diamond area
thoroughly, then rinse with clean water
and wipe dry.
Dress a Diamond Wheel
Place the Accu-Finish machine in
the horizontal position. Place a cloth
or large rag over the table assembly
to protect from dust. Wet wheel with
water soluble wetting agent and turn
machine ON. Apply Wheel Cleaning
Stick (#001-783) to the wheel and
slowly transverse the stick across
the face of the wheel, maintaining a
moderate, uniform pressure. Remove
stick and turn machine OFF. Clean
abrasive debris off wheel and machine.
Remove cloth from table assembly and
return machine to vertical position.

Accu-Finish diamond wheels
are designed for this slow RPM
application. Most materials are
compatible with Accu-Finish wheels,
including ceramic, carbide, borazon,
HSS, and polycrystaline diamond.
We recommend wetting the wheels
with wheel wetting agent. The
concentrate supplied with you
machine is ideal (#001-659, 3 Pack
/ #001-660, 12 Pack). Occasionally
mist the wheel with the agent from a
hand spray bottle. A dry nishing will
give fair results, but wet nishing will
perform better than dry.
Diamond wheels provide long
term economy and performance in
abrasive service if used correctly.
Diamond is the hardest material
known, although the bond which
holds the diamond particles in place
can be damaged. Grooving the wheel
by gouging the bonding material is
the biggest error. The ner the grit,
the easier it is to damage the wheel.
The user should not be afraid of using
moderate pressure while cutting as
the wheels are designed for this.
