WFL MILLTURN TECHNOLOGIES unveiled its new M20 Millturn complete machining center at EMO 2021, and positioning it for applications that require a compact and powerful machining capabiity. The aim in 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 – which also means heavy roughing cuts can be made without compromise.
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 44 kW means even hard-to-machine materials can be handled with ease. The milling spindle with up to 25 kW and 20,000 rpm 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 means that the upper and lower systems 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.
The tool can be moved up to 100 mm below the turning center, so drill patterns with diameters of up to 200mm can be produced on the face with a high level of precision and without turning the C-axis.
The machine makes it possible to easily integrate 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 also will be presented to the public for the first time at EMO 2021. The workpieces are supplied on a strip accumulator.
Furthermore, it is possible to automatically switch the tool to the lower individual tool holder with B-axis. This makes it possible to set up the tools parallel to machining time and to automatically access the stock in the magazine. Stored tools can therefore be placed in the upper and lower tool holder. With the 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 300 mm and a workpiece weight of 15kg. For shaft parts, a workpiece diameter of 100 mm and a workpiece length of 300 mm is possible. Learn more at www.wfl.at
