Maintenance
Repair
of the grinding machine.
ATTENTION!
Properly performed regular maintenance is an essential
prerequisite for
operational safety,
failure-free operation,
a long working life of the grinding machine and
the quality of the products which you manufacture.
Installations and equipment from other manufacturers must also
be in good order and condition.
4.1
Safety
WARNING!
The consequences of incorrect maintenance and repair work
may include:
extremely serious injuries to those working on the grind-
ing machine and
damage to the grinding machine.
Maintenance and repair work on the grinding machine must
be carried out by qualified technical personnel only.
4.1.1 Preparation
WARNING!
Only work on the grinding machine if it has been
disconnected from the power supply.
4.2
Inspection and maintenance
INFORMATION
The bearing is lifetime-lubricated. It is not necessary to lubricate it
again.
WARNING!
Grinding wheels must be replaced, if there is an excessive
distance between the external diameter of the grinding wheel and
the completely readjusted workpiece support.
WARNING!
Cleaning brushes may be used only on the grinding machine
GZ40C.
Grinding wheels must not be installed in places that are designed
for cleaning brushes.
The polishing machine GZ40P may only be equipped with
polishing wheels.
Non-compliance leads to considerable hazards for the operator
and persons in the immediate vicinity.
4.3
Replacing a grinding wheel
Disassemble the protective cover of the grinding wheel.
Loosen the shaft nut.
Use the counterhold on the drive shaft to loosen the nut. Make
sure you use the correct direction to loosen the nut. There is a
left-hand thread on the left-hand side of the grinding machine
and a right-hand thread on the right-hand side.
Pull off the grinding wheel and the retaining washer from the
shaft by hand.
Check the new grinding wheel for visible damage prior to
assembly.
