hydraulic 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
Only use tool tapers with a centric through-hole.
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.
Ü
Make sure that the shaft of the HF spindle has come to an absolute stand-
still.
Ü
Switch on the hydraulics for “cylinder forward”.
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
Insert the tool.
Ä
Insert the tool up to the contact surface of the clamping taper.
Ü
Switch on the hydraulics for “cylinder back”.
Ü
Wait for 1-2 seconds after the tool change.
Ü
Start the HF spindle.
