The universal tooling system UTS
A281
Manual (radial) clamping
By turning the actuator to the right (approx. 3.5 revolutions)
the lock rod moves towards the centre. Due to the angled
ball tracks the clamping balls are pushed outwards into the
bores of the cutting head, drawing it towards the location face
and into the adapter. During this movement the adapters are
elastically deformed allowing true taper and face location.
This results in a stable and precise connection.
With manual clamping the actuator has to be fixed applying a
defined torque:
Torques:
UT40 16 Nm
UT50 32 Nm
UT63 50 Nm
Unclamping is achieved by turning the actuator to the
left. The lock rod moves outwards and the clamping balls
retract.
The taper remains in the self-locked condition (taper ratio
1:10). The cutting head is released via positive axial thrust
through the bump-off pin.

Manual clamping is mainly applied in the field of modular
constructions and lathes with longer tool changing intervals.
The extremely short and compact construction represents a
further advantage.
