WFL Millturn Technologies is introducing the new M20 MILLTURN complete machining center for the first time at EMO 2021.
The aim when developing the M20 was to introduce a particularly robust machine with the highest possible long-term accuracy. The machine frame is made from spheroidal graphite iron, ensuring optimal stability plus outstanding damping properties. This also means heavy roughing cuts can be made without compromise.
The most ground-breaking aspect, however, is the machine's new design. The continuous toughened-glass front features an integrated performance data display and a touch panel for conveniently operating the tool magazine from the front of the machine. The working area is perfectly illuminated thanks to ultra-efficient and bright LED lights.
The M20 is available with a tailstock or counter spindle and features dynamic and powerful drives. The turning-boring-milling unit with integrated spindle motor and a B-axis with torque motor are entirely new features. The turning output of up to 44kW means even hard-to-machine materials can be handled with ease. The milling spindle with up to 25kW and 20,000rpm is ideally equipped for all machining tasks.
In terms of the tool system, there is the option of using HSK 63 or Capto C6. The individual tool holder with B-axis on the lower slide is a real highlight. The upper and lower system can be used simultaneously, and both systems are supplied by a reliable and dynamic tool changer from a shared magazine. This allows even complex components to be machined with optimal efficiency.
Another key benefit of the machine is the possibility of easily integrating a wide range of automation options. Depending on the customer's requirements, articulated robots, gantry loaders or an integrated production cell with the associated peripheral equipment can be implemented.
The newly integrated production cell -- intCELL -- is fitted on the right-hand side of the machine and will also be presented to the public for the first time at EMO. The workpieces are supplied on a strip accumulator.
With an integrated loading concept, WFL has reduced the space requirement by 50% in comparison to a conventional production cell. The M20's integrated loading feature is designed for chuck parts with a diameter of up to 300mm and a workpiece weight of 15kg. For shaft parts, a workpiece diameter of 100mm and a workpiece length of 300mm is possible.
When designing the M50, WFL implemented some of the features of the larger M80. The machine's existing potential is fully utilized, particularly in terms of the increased drive power, combined with the HSK-A100 or Capto C8 tool accommodation. The turning diameter is available up to 670mm and the fully developed, proven machine concept of the M50 MILLTURN has also been given an attractive ergonomic finish.
A separate pick-up magazine is also available for very long and/or heavy tools. Workpieces with a length of 1600mm can be automatically inserted and changed. The standard disc magazine can be expanded to up to 200 positions.
