Grinding wheels: maintenance and
replacement
Dressing
Grinding wheels wear away. To prolong their
useful life you can dress the wheels from time to
time. Preferably by using the Creusen hand
dresser. This is made of coarse silicon carbide.
Use the hand dresser:
- to give the wheel a neatly rounded shape again.
This prevents vibration. After being dressed, the
wheels will grind better because new, sharp
granules will be released.
- to remove any paint or oil remnants left behind
on the wheel after grinding tools. Paint or oil
remnants will (partially) clog up the rough surface.
- if you grind tools made of a metal other than for
which the wheel is intended, the granules will be
smoothed off instead of broken out. Here, again,
dressing is recommended.
Replacement
If the grinding wheel diameter has become too
small because of repeated use, the wheel needs
to be replaced. When doing so, bear the following
points in mind:
- Preferably fit new Creusen grinding wheels.
These comply with the highest quality standards.
- The maximum radial oscillation of a new grinding
wheel must not exceed approx 0,3 mm or a
maximum of 0,5 mm in an axial direction, in each
case measure at the circumference of the wheel.
- Each grinding wheel must carry the following
information: maker's name, type of binder,
dimensions, maximum permissible speed. The
grinding wheel must also be fitted with soft card
or rubber plates.
- Always store spare grinding wheels in a dry place
and at a uniform temperature.
- Always remove the plug from the socket before
replacing a grinding wheel.
- First carry out a 'ringing' test before fitting a new
wheel. A light tap on the wheel should produce a
clear ringing sound. If not, consult your dealer.
- Use only the clamping plates which are fitted
standard to the Creusen machine.
- After mounting new grinding wheels, always test
them by running them in for about 5 minutes.
Caution: make the test with the wheel guard and
cover fitted, and with the spark arrestors and eye
shields in the correct position. Allow the machine
to run without load.
The Creusen Professional as a
polishing machine
If you want to use the Creusen Professional for
polishing work, ask your dealer for the Creusen
polishing machines or for the special tapered
extension spindles. These are an exact fit on the
shaft of the grinder. The tapered spindles have an
external thread on which the polishing wheels
can be easily screwed. The cylindrical section of
the spindle is marked with a letter 'R' or 'L'. The
spindle marked L should be fitted on the left hand
side of the machine and the spindle marked R on
the right hand side. If they are fitted the wrong
way round, the polishing wheel will run off the
spindle when it starts to rotate.
Within the European Comminities and the
Member States it is obliged to mount polishing
covers on the polishing machine. Creusen covers
are available in 150 ø and 200 ø mm.
The Creusen Professional with steel wire
brush
Fit only Creusen steel wire brushes. The special
metal core in this brush fits precisely on the
grinder shaft (see fig.3). Besides, this ensures
safer working: Creusen steel wire brushes are
fully
suitable for use within the wheel guard and guard
cover, which is absolutely necessary and obliged.
