MILLTURN – The First Choice for the Crankshaft Industry

MILLTURN offers the best alternative to conventional manufacturing methods for the complete machining of crankshafts, including deep drilling of oil ducts or gear production, especially for large crankshafts or prototypes. In particular, the machining of forged components places high demands on the manufacturing process due to their metallurgical structure. Deformations during machining caused by unstable workpiece geometries can only be effectively compensated for by machine and software functions specially developed by WFL. Regardless of whether high-performance rough machining or precise pre-finishing is required – all crankshaft geometries can be completely machined on the MILLTURN from WFL.

The production times for crankshafts are significantly reduced due to optimum precision and stability, combined with automatic machining of all tools and measuring probes.

Thanks to the wide technological range of our multifunctional turning-boring-milling centers and our ten years of experience in crankshaft machining, our customers can ensure the highest level of productivity.

MILLTURN – The First Choice for the Automotive Industry

For leading automotive manufacturers and their component suppliers, there is no alternative to the MILLTURN for prototype and small series production. The extensive automation options of the MILLTURN (e.g. the gantry loader system for feeding and removing workpieces) make complete machining attractive even for large volumes. The MILLTURN is often the best alternative – especially when machining hardened materials, gears, tight tolerances and high surface quality.

The machining times of complex workpieces in this sector are significantly reduced thanks to optimum precision and stability, combined with automatic machining of all tools and measuring probes. Thanks to the wide technology spectrum of our multifunctional turning-boring-milling centres and our decades of experience, our customers can rely on the highest level of productivity.
