9 Commissioning
DANGER: Due to flying parts.
If the speed is selected incorrectly, the HF spindle or the tool may be de-
stroyed and their fragments may be flung out.
u
Note the maximum speed for the selected tool.
u Note the maximum speed for the HF spindle.
u The maximum permissible speed of the HF spindle for commissioning /
processing is always the
lowest specified speed.
Example of design: Inserting the
shank
Note: Ensure functionality.
u Never operate the HF spindle without a clamped tool shank.
If no tool shank is clamped:
q
The clamping system is damaged by the centrifugal forces.
q The clamping system is shifted.
q The balance of the HF spindle is affected.
q
The bearing is damaged.
Example of design: Clockwise
Ü
Turn the shaft of the spindle at least ten times by hand.
Ü Before storing and before commissioning only clean the cooling duct with
compressed air.
9.1 Running-in schedule
Duration of load (minutes)
Max. load (%)
Ü Put the HF spindle into operation with a clamped tool (without machining)
for approx. 10 minutes.
Ü The speed in this case should be no more than 20% of the maximum per-
missible speed for the HF spindle.
Ä
See definition: Max. permissible speed
Ü Allow the HF spindle to run for approx. 2 minutes at a maximum of 50% of
the maximum permissible speed.
Ü Operate the HF spindle for approx. 2 more minutes at a maximum of 80%
of the maximum permissible speed.
The HF spindle is now ready for operation.
9.2 Daily start-up
Proceed as follows to preheat the grease lubrication of the bearing and to
protect it:
Ü Operate the HF spindle with a clamped tool (without machining).
Ä
Approx. 2 minutes.
Ä
At maximum 50 % of the maximum permissible speed.
