WFL Millturn Technologies Offers Integrated Tool Loading

WFL Millturn Technologies developed the M20 Millturn to achieve the highest possible long-term accuracy. The machine frame is made from spheroidal graphite iron, which the company says optimizes stability and provides outstanding damping properties.

The M20 is available with a tailstock or counter spindle and is said to feature dynamic, powerful drives. The turning-boring-milling unit with integrated spindle motor and a b-axis with torque motor are new features. The turning output of up to 44 kW means even hard-to-machine materials can be handled with ease. According to WFL, 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 upper and lower system can be used simultaneously, and both systems are supplied via a reliable tool changer from a shared magazine, which is said to enable complex components to be machined with optimal efficiency.

WFL says it is possible to automatically switch the tool to the lower individual tool holder with b-axis. Stored tools can be placed in the upper and lower tool holder. With the integrated loading concept, WFL has reportedly 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 15 kg. For shaft parts, a workpiece diameter of 100 mm and a workpiece length of 300 mm is possible.

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.
