8.2 Wheel balancing
With the buffer unplugged from the power
source , and arbor nuts snugged down, rotate
wheels by hand and observe their motion.
A buffing wheel has proper balance when:
1. The wheel’s outside face spins true and round;
that is, its circumference rotates concentric to
the arbor.
2. There is no side-to-side wobble.
8.2.1 Adjusting concentricity
If the outside face is not rotating concentric to arbor,
try shifting the wheel closer to arbor centerline
before tightening the nut.
A wheel rake (not provided) may also be used to
shape the buffing wheel for better concentric
rotation.
8.2.2 Correcting side-to-side wobble
The IBG-SSB series Buffers have large, machined
flanges, making wobble unlikely if a good quality
buffing wheel is used. Should a wheel exhibit need
for adjustment:
1. Loosen nut and rotate the outer flange a little.
Snug the nut and spin the wheel by hand to
check.
2. If wobble still exists, continue repeating step 1,
rotating outer flange incrementally in the same
direction. Make sure to keep the wheel in the
same position each time.
3. If complete rotation of outer flange has proved
ineffective, remove nut, outer flange, and wheel
(keep wheel in same orientation by placing a
pencil mark on it somewhere for reference).
Then rotate inner flange about 90° and repeat
the above steps for the outer flange.
4. Continue this combination of flange movements
until the wobble is eliminated.
If required, a shim made of paper or card stock may
be placed between flange and wheel side.
NOTE: Slight wobble may still exist at spin-up and
spin-down, but will not affect normal speed
operation.
8.3 Buffer maintenance
Periodically use a wheel rake (not provided) to clean
and shape the buffing wheels.
8.4 Additional servicing
Any additional servicing on the buffer machine
should be performed by an authorized service
representative.
