ProfiTurn M
Overview
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.
Key Benefits
Machine Technology
- Box-in-box Design of the Milling Tower
Of all conceivable solutions for horizontal machining, box-in-box design is the most stable one with regards to cutting force and temperature influence. The milling tool holder or the milling spindle is mounted on the column, which is cast in one piece, and hydrostatically guided in the Y-axis. The stiff, temperature-symmetric and wear-free design guarantees highly precise machining results.
- Headstock with Master/Slave Drive
The headstock, made of cast iron and strongly ribbed, ensures excellent concentricity and performance. The faceplate is made of cast iron, as well and can safely accommodate workpieces with weights of up to 250 t. Modern drive concepts, such as a Master/Slave drive, allow for the machining of workpieces with the highest precision and maximum power.
- Tailstock for Mounting Workpieces between the Centers
The tailstock is also made of a closed, ribbed cast-iron housing. Generously dimensioned anti-friction bearings for the center shaft and the quill respectively ensure excellent concentricity.
- Hydrostatic Guides
Both the carriage and the bed of the ProfiTurn M are hydrostatically guided. The advantage: an unlimited service life even at the highest performances. The “stick-slip effect” is avoided, which allows for very accurate positioning. Oil pockets effectively damp vibrations and thus support the extremely precise working of the machine.
