WFL Millturn Offers Complete Machining at AMB 2022
At AMB 2022, WFL Millturn Technologies will be presenting the new M20 MILLTURN complete machining center for the first time. Alongside gear skiving technology, there is clear trend toward automation and the integration of sensors. The latest solutions from WFL range from smart software to screw programming through to intelligent tools and clamping devices.
The M20-G showcased at AMB is equipped with an innovative automation solution - the intCELL. The integrated production cell is fitted on the right-hand side of the machine, the workpieces are supplied on a strip accumulator. With the integrated loading concept, WFL has reduced the space requirement by 50 percent 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.
The turning-boring-milling unit with integrated spindle motor and a B-axis with torque motor are entirely new features. The individual tool holder with B-axis on the lower slide is another 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, and the setup of the tool turret is no longer necessary. The tool can be moved up to 100 mm below the turning center, so drill patterns with diameters of up to 200 mm can be produced on the face with a high level of precision and without turning the C-axis.
The new M50-G MILLTURN generation, with greater center distance and improved performance, will be another highlight of the AMB. The optional center distance of 6,000 mm enables efficient machining of long shaft parts. 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 670 mm and the fully developed, proven machine concept of the M50 MILLTURN has also been given an attractive ergo-nomic finish. A separate pick-up magazine is also available for very long and/or heavy tools. Workpieces with a length of 1,600 mm can be automatically inserted and changed. The standard disc magazine can be expanded to up to 200 positions.
On this machine, trade fair visitors will be able to witness a turbine blade/screw being machined live. Com-ponents such as turbine blades or plasticizing screws require both dynamic and stable machining concepts. A special clamp from the manufacturer Grasch can be used to clamp rectangular raw materials easily and securely, a fundamental requirement when machining turbine blades. Technologies known as ‘helical spiral milling’ and ‘helical longitudinal milling’ are used to machine the blade.
The ICOtronic tool, which is fitted with sensors, provides information on the machining process as close as possible to the cutting edge. This should not only optimize milling processes in the future, but also in-crease the machines’ productivity. The demo at AMB will give a small insight into WFL’s wide variety of development projects.
