Description
- 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
Control HEIDENHAIN iTNC530:
- Heidenhain iTNC530 with TFT flat-panel display and vertical and horizontal soft-key rows
- Main operating panel with alphanumeric keyboard, machine operating panel, override potentiometers, PC key set and touch pad
- HR550 FS portable radio handwheel
- TRIMILL Teleservice - remote service
- TRIMILL Kinematics - Automatic adjustment and control of the rotary axis kinematics (The kinematics adjustment is done with a calibration ball with the help of the 3D measuring probe)
2-axis fork milling head T21C:
- TRIMILL fork milling head T21C mounted under the milling slide with swiveling high-frequency main spindle and built-in rotary (C) and swiveling axis (B)
- Both axes with hydraulic, centric clamping (B-axis on both sides)
- B and C axes are designed as simultaneous axes
- Jacket cooling of the main spindle
- Automatic tool clamping
- Blow-off device for tool holder and tool taper
- B-Axis bearing on both sides, drive via 2 water-cooled torque motors
- Drive of C-axis via water-cooled torque motor
- Direct angle measuring systems in the C axis (incremental) and B axis (absolut)
