functioning tool monitoring is safety related, and therefore the test has to be carried out under
high care. For damages caused by negligent testing, we are not liable!
2. Does the cooling system work properly? Are ventilator slots or radiator ribs whether clogged
nor covered? Is the coolant circulating properly and no foreign particles or air bubbles are in
the coolant?
3. Is the electrical connection of the spindle done properly and undamaged? Are all cables and
wires in proper condition?
4. Is the motor spindle mounted safe and the fixtures are tight and safe?
5. Is the used tool appropriate for the nominal rpm of the motor spindle and is it balanced
correctly?
6. Can the spindle shaft turn free and is not blocked by other parts? Is the tool not in contact
with the workpiece?
8.2 Running-in of the spindle
A cold motor spindle has to be run-in carefully before working with it to ensure that the bea-
rings reach operation temperature slowly. The running-in times must be doubled if the spindle
is factory new, not used for over one week or a change of the bearings has taken place. With
shutdown times of less than 1 hour, no new retraction is required.
For running in, the speed has to be adjusted to the minimum (e.g. 6.000rpm) and to be run
for at least 1 minute at this rpm. After one minute, the rpm can be increased in steps of 25%
of the nominal rpm for another minute. The increase in these steps is done until the spindle is
running at nominal speed.
For spindles with a rpm of more than 24.000rpm, additionally a grease dispension
run is necessary:
Adjust the rpm to 33% nominal speed (e.g. 14.000 rpm at a 42.000rpm spindle). Let the
spindle run for 1 minute at this speed. Then pause for 2 minutes. Repeat this run-pause interval
5 times overall. Now increase the speed to 66% of the nominal value. Also make 5 times a run/
pause interval of 1minute / 2 minutes.
