TRIMILL TYPE VF3016 5 AXIS GANTRY TYPE VERTICAL MACHINING CENTER

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 thermo symmetric 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

HEIDENHAIN iTNC530 CNC Control

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 (absolute)
