Tool change
CAUTION: Danger of being drawn in by rotating shaft.
If the shaft is still rotating, fingers and hands may be drawn in and crushed.
u
Only change the tool if the shaft is at a standstill.
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.
10.1
Clockwise and counter-clockwise
Sample illustration:
Direction of rotation indication
The HF spindle clamping system is designed for clockwise and counter-clock-
wise rotation.
Ü
Only use tools with the correct direction of rotation for the HF spindle.
Ü
Only use tool mounts with the correct HF spindle direction of rotation.
Ü
Set the HF spindle direction of rotation on the FC to match the direction of
rotation of the tool / tool mount used.
10.2
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.
