Pneumatic taper change
DANGER: Due to flying parts.
The taper cleaning could build up air pressure in the hollow shank taper dur-
ing the tool taper change. This air pressure flings out the hollow shank taper
in the case of sudden release.
u
Always switch off the taper cleaning when the hollow shank taper is ap-
prox. 1-2 mm away from the contact surface.
Tip: Ensure concentric run-out quality.
u
Keep collet, clamping nut, contact surface, shaft, tool taper, and tool
mount clean at all times.
u
Check the tool taper mount.
It must be free of damage and clean when switching to the HF spindle.
Insert the tool up to the contact
surface of the clamping taper.
Ü
Make sure that the shaft of the HF spindle has come to an absolute stand-
still.
Ü
Switch on the compressed air for the tool change.
Ü
Remove the tool.
Ü
Clean the inner taper of the tool mount and the inner taper of the shaft
with the felt cleaning taper.
Ü

Ä
Insert the tool up to the contact surface of the clamping taper.
Ü
Switch off the compressed air for the tool change.
