- Electrowelded cross-beam:
- made of steel to reduce
- moves on linear guides 2+2 and 6 roller pads, 3 on each guide
- cross-saddle move on longitudinal guides with sliding pads 3+2
- cross-slides allow to locate 3+3 ram slide pads in the center of ram sliding surface, which considerable increases axes speed and reduces and geometric inaccuracy
- Axes:
- kinematic characteristics of axes contribute to high speed and acceleration; gantry axis is driven through ball-screw or rack and pinion, depending on the machine feeds
- rack and pinion uses the dual drive system. Two other axes are driven trough ball-screw
- Fork head:
- can work in continuous mode or on the axes clamped with hydraulic breaks
- Its particular design with a double misalignment A axis vs C axis, and spindle axis vs A axis
- guarantees a good penetration in deep cavities, a wide A axis travel, an increase of the working volume with respect to traditional geometry heads
- rotary axes are driven through double gears to prevent backlash
- Main head components are produced of cast iron for better vibration damping
- Semi-finishing and finishing of steel and cast iron dies
- Complete machining of aluminum alloy aerospace workpieces and production of dies and molds
- Machining parts of composite materials containig resins, graphite and carbon fibers thanks to additional accessories
- Chain tool magazine placed on the floor ( from 24 to 40 positions)
- Dual chip conveyor
- Laser tool measuring device
- Contact workpiece measuring probe with radio data transmission
