LTF La Prora U 320 CNC milling  

Company Authorized to Use the Mark

Characteristics and Details

The machine is mounted on a monobloc base that supports the two linear X and Z axes, the fixed column of the Y axis, and the cabin containing the coolant reservoir. The head of the motor carrier is above the two X and Z axes and pivots in the horizontal plane. The motor spindle has a power rating of 13.5 kW (10 HP) at 10,500 rpm and an adjustable speed range from 2,000 to 12,000 rpm.

The new typology of its traversing movements makes this machine so versatile that it can be used as a forming machine for all effects. Despite its capabilities, the machine has limited overall dimensions, just slightly larger than the current U95 model.

Rotating wheelhead.

Automated wheel and magazine change.

The quíckfít of the motor spíndle, linked to the PLC, has made ít possibie
to mount this accessory on the machine whích we belíeve to be extremely
useful.
With the total management of the thís optíonal makes it possíble to
resolve three important and age-old problems for the manufacturer s of
machíne tools.
1 Exclusion of operator íntervention to change wheels savings on machine
stoppages and therefore on tíme .
2 Exclusion of the coaxial three wheel train which often causes problems
of collísíon and speed íncompatíbility; in other words, it makes it possible
to work wíth one or two wheels at the most.
3 A notable economíc saving on the wheel store and wheelholders it is
not necessary to have packs of wheels ready for one use only in store .
In the magazíne, wíth 6 statíons, síx síngle wheels or síx couples of wheels,
with a maximum díameter of 150 mm. can be housed.
The system ís equípped with 4 atm blow pressure, for cleaning the cones
both on the motor and on the magazine at each change.
