TRIMILL VF3016 5 Axis

TRIMILL VF3016
built: 2017

control: HEIDENHAIN iTNC 530 HSCI
• Extremely stable, 5-axis machine, specially developed for tool,
mold and die making as well as for demanding single-part production.
• 5-sided machining in one clamping with 2-axis fork milling head.
• Designed as an overhead gantry, resulting in controlled dynamics and accuracy.
• Travel speeds up to 40,000 mm/min to increase productivity
• Closed design of the double beam and cross slide with internal, all-round guided
milling slide (box-in-box design).
• Consistently good milling results due to load and thermosymmetric design.
• Stationary workpiece for consistently good surface quality
• Very compact dimensions with large working area
• High productivity due to roughing and finishing in one set-up.
• Ergonomic operation due to ground level accessibility

design/axis concept:
AC servo motors 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 preloaded, water-cooled motors
2 ball screws each in the Y and Z axes
Guides of all linear axes are designed as preloaded roller guides
Hydro-pneumatic counterbalance of the Z-axis via 2 cylinders
Stationary frame components made of mineral casting, main moving components made of gray or nodular cast iron
Double beam in load- and thermo-symmetrical design, movable together with the milling slide in longitudinal direction (X-axis)
4-fold guided cross slide movable within the double beam (Y-axis)
Milling slide also guided 4 times, can be moved vertically in the cross slide (Z-axis)
Thermosymmetrical guidance of the slide, thus maintaining the linearity when travelling in "Z"
Machine table fixed on the foundation independently of the machine
