Profi Turn M

ProfiTurn M at a Glance

The mill-turning machine ProfiTurn M has been designed specifically for the complete machining of complex, rotationally symmetrical workpieces. Both turning and milling units, as well as boring and grinding units can be attached to the Masterhead interface located at the milling tower. The result is highest efficiency. All stages of the machining process are performed on a single machine and multiple set-ups, which are both elaborate and costly, are reduced.

Whether turbine or generator rotors or heavy forged parts – the ProfiTurn M has been developed for the precise and efficient machining of demanding workpieces with a diameter of up to 4.2 m, a length of 25 m and weights between 20 and 250 t. The machine is characterized by an overall concept that is both operator and maintenance-friendly and by its energy efficiency.

A Modular Concept for Custom Machines

The reliable stiffness and modular concept of the ProfiTurn M are two of its major advantages. Each machine is designed individually, based on the customer’s requirements.

Depending on the diameter of the workpieces to be machined, the ProfiTurn M is equipped with one or two beds. The box-in-box design of the milling tower, which is extremely rigid, guarantees the highest precision even when great cutting forces are involved. The completely encased machine operates precisely and wear-freely thanks to the hydrostatic guides both in the carriage and the bed. Depending on the customer’s requirements, either a high-performance boring and milling spindle or a ram is integrated in the traversing column. A tool and unit changer can be added for fully automatic operation of the machine.
