LT800 / LT1000 / LT1250

Rigid machine frame of high quality cast iron with wide induction hardened and ground guideways.

Powerful main motor with frequency invertor Schneider and 4 step manual control gear box ensure high value of the spindle torque and infinitely variable speed.

High repeatability and positioning accuracy ensured by pre loaded ball screws and powerful servo motors on Z and X axes.

The CNC Siemens 802 Dsl T/M Plus is an intuitive easy to learn control system with extensive cycle options. The CNC systems and servo drives Fagor, Fanuc and Heidenhain available also.

Two electronic hand wheels on the control panel for manual operation.

Manual tool turret Multifix type or automatic turret head Baruffaldi or Duplomatic according to the clients’ choice.

Powerful coolant system and a central lubrication system are included in the standard equipment of the machine.

Motorized tailstock.
