Main Units
Bed and Table
Made of special cast iron with strong ribbing for high stiffness.
Table diameter: 2000 mm.
Main shaft supported by two taper bearings.
Table Drives
Equipped with a Heidenhain encoder (1024 pulses) for constant speed, feed-per-rev, and threading.
Drive: Siemens 44 kW AC brushless motor, variable speed, through a 3-range gearbox.
Frame
Consists of two columns, two spacers, the bed, and an upper cross beam.
Cross rail guided on high-precision guideways, driven by AC asynchronous motor, screw-nut mechanism, and reducers.
Cross Rail
Cast-iron, box-type, ribbed for stiffness.
Contains gear train for head displacement.
Head movement: AC brushless 15 Nm motor, reducer ratio 5, ball screw with precision bearings.
Equipped with precision transducers for position control.
Vertical Rail Head
Slide: Horizontally displaceable on cross rail, AC brushless 15 Nm motor, reducer ratio 7, ball screw.
Ram: Vertically displaceable inside ram support, AC brushless 15 Nm motor, reducer ratio 7, ball screw.
Both movements monitored by high-precision transducers.
Ram hydraulically balanced.
5-position manual turret for toolholders.
Anti-friction plating on guideways for smooth displacement.
