78hp milling performance sets new standards

WFL Millturn Technologies will be presenting the new M80 Millturn/3000mm from 10th to 15th of September 2012 at IMTS. Since its launch in 2011, this new machine model has proved to be a real hit on the market. With a milling performance of 78hp, the M80 Millturn performance is right at the top of its class! Besides the M80 Millturn, WFL will be demonstrating its machining know-how on an extremely complex workpiece. An incomparable range of innovations in technology and software will also be on show.

One important aspect of the new M80 Millturn is the enormous variety that can be created from the extensive and enhanced WFL modular machine concept. This approach enables the ideal configuration to be assembled from the standard tool kit for every conceivable customer requirement. As a result, it is possible to combine the widest range of machining systems on the upper and lower slides with all the internal machining solutions available from WFL. All center-to-center distances (except 39in) are also available in a double spindle version. The machine concept is based on minimised tool and workpiece distances from the slide guideways and widest possible guideway distances, resulting in optimum rigidity and ideal geometries. The machine control is the Siemens Sinumeric 840D Solution Line in combination with the new Sinamic drives. The new 19“ monitor, the height and tilt angle of which are adjustable, is particularly user-friendly.  

At the heart of the machine is the new Turning-Boring-Milling unit, which in terms of its performance data and component sizing is designed to handle very heavy-duty machining applications. The innovative design of the bottom guideways means that the maintenance-prone telescopic covers are no longer required. The chip flow is better than in other comparable machines. The minimum distance between a steadyrest slide and tailstock or between two adjacent steadyrest slides is just 2in, resulting in much more stable clamping conditions than on conventional machines. In the standard version of the machine, the steady rest slide and tailstock come equipped with their own NC drives and can therefore be positioned independently and simultaneously.

The new tool magazine is easily accessible from the front and boasts a particularly compact, stable and practically maintenance-free design. The highly dynamic tool shuttle with rack-and-pinion drive carries a tool changer with all but linear axes, thus avoiding any rotation-induced centrifugal effects. Even tools up to 77lb weight and 35in length are changed safely and quickly. For heavy-duty internal machining applications, either a 2-station pick-up magazine or a 15-station heavy duty boring bar changer is available for tools up to 67in and 98in length respectively.
