The UTS Quick Lock

MAXIFLEX UTS quick lock full actuation is
achieved by a 140° rotation of an eccentric
cam. Through the cam movement the lock
rod is moved axially. The tried and tested
principle of ball clamping is maintained,
but the defined clamping force is produced
through disc springs. Both, when clamping
and releasing cutting heads, the rotation of
the cam is limited through a fixed stop.

A torque key is no longer necessary for the
TIZIT MAXIFLEX UTS quick lock.

UTS - manual clamping for tool modules

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.

By means of the standardised tool interface
TIZIT MAXIFLEX UTS every driven unit can
be applied for all machining methods, namely
drilling, tapping and milling.
With reference to practical operation this means
a considerable reduction of tool changing times,
higher flexibility in production as well as lower
investment costs, compared to conventional
driven units.
