Travel
X-axis (longitudinal): 3,000 mm
Y-axis (transverse): 1,600 mm
Z-axis (vertical): 1,200 mm
B-axis (swivel axis milling head) +/- 100 °
C-axis (rotation axis milling head) +/- 240 °
Structure / Axis concept
AC servomotors with digital control for all axes
Gantry drive of the X-axis
Rack and pinion drive in the X-axis, backlash-free due to electrically
prestressed, water-cooled motors
2 ball screws each in the Y and Z axes
Guides of all linear axes are designed as prestressed roller guides
Hydro-pneumatic weight compensation of the Z-axis via 2 cylinders
Stationary frame components made of mineral casting, movable main
components made of grey or nodular cast iron
Double beams in load- and thermosymmetric design, movable together
with the milling slider in the longitudinal direction (X-axis)
4-fold guided cross slide can be moved within the double beam
(Y-axis)
Milling slide also guided 4-fold, movable vertically in the cross
slide (Z-axis)
Thermosymmetric guidance of the slider, thus maintaining linearity
when driving in "Z"
Machine table fixed on the foundation independently of the machine
Feeds and rapid traverses
Rapid traverse X-, Y- and Z-axis: 40,000 mm/min
Rapid traverse B- and C-axis: 50 rpm
Axis accelerations (X, Y and Z) 4 m/s²

2-axis fork milling head T21C
TRIMILL fork milling head T21C mounted under the milling slider with
swivelling high-frequency main spindle and built-in rotary (C) and
swivel axis (B)
• Both axes with hydraulic, centric clamping (B-axis on both
sides)
• B- and C-axis are designed as simultaneous axes
• Jacket cooling of the main spindle
• Automatic tool clamping
• Blow-off device for tool holder and tool cone
• Bearing of the B-axis on both sides, drive via 2 water-cooled
torque motors
• Drive of the C-axis via water-cooled torque motor
• Direct angle measuring systems in the C-axis (incremental) and
B-axis (absolute)
