Technologies and Materials
5-Axis Milling (simultaneous and 3+2, AC/BC/AB)
Complex machining in a single setup for tight tolerances and high surface quality, e.g. for aluminum, stainless steel, titanium and plastics.
Double-Spindle Machining (200–1,200 mm spindle distance)
Increases productivity in medium and large series through parallel machining.
Mill-Turn (vertical and vertical/horizontal)
Turning, milling and drilling in a single setup reduce setup and handling times.
Profile Machining
Milling, threading, countersinking, reaming and sawing of extruded profiles up to 150 x 150 mm made of aluminum and light metal alloys.
Micromachining (Micro5, Micro5 XL)
Micrometer-precise machining of small components on a minimal footprint, e.g. for medical and precision engineering.
Gear Technology (Skiving, Hobbing, Broaching, Impact Gear Milling)
Gears to IT7 and better, suitable for large and small series.
Friction Stir Welding
Joining technology for aluminum alloys without filler material and without melting, low distortion.
Automation (Variocell UNO/MO, Pallet Changing, Robotics)
Automated cutting cells for reduced cycle times and higher system availability.
Refurbishment/General Overhaul
Overhaul in three categories (performance-tested, partially and completely overhauled) with tolerances like a new machine for complete overhauls.
