Millturn machine

The M70 MILLTURN features a sophisticated working area concept for working lengths up to 8,000mm and for a swing diameter up to 850mm. Thanks to the WFL modular system, it offers enormous variety and can be tailored to each customer’s requirements.

In addition, the new M70 MILLTURN offers optimum stability and geometry for maximum precision, reliable machining thanks to high pull-in forces at the tool interface, and additional options for highly productive deep-hole drilling processes and special technologies. With the capability to machine workpieces weighing up to 5,000kg, the MILLTURN is suitable for heavy-duty applications.

The M70 MILLTURN features the disc tool magazine or chain magazine with up to 200 tool stations and capacity for tools weighing up to 35kg with a maximum length of 900mm. In addition to automatic tool changes, the setup process can also take place in parallel to the machining time, allowing the magazine to be tooled for different orders without any loss of time.

Two magazine variants are also available for heavy special tools weighing up to 200kg each.

The optional WFL prismatic tool interface by means of a large prismatic tool accommodation enables the use of tools exceeding the maximum dimensions of standard tools.

The machine also features extremely reliable main and milling spindle drives. Combining maximum precision with great adaptability, the M70 MILLTURN is well-suited for customers with changing requirements.

For the M70 MILLTURN with its large drilling and turning tools, high torque and high performance are extremely important in maximizing the performance of the tools.

Enhanced performance thanks to WFL prismatic tool

Specially developed tools designed to work with the MILLTURN enable precision machining of complex workpieces. As hard to access machining areas often require the use of long special tools, the use of robust prismatic clamp holders means boring bars, solid drills, and angular heads can be attached to the turning-boring-milling unit in a highly stable manner. The WFL system boring bar enables automatic changeover of the cutting heads. Two magazines are available to provide automatic handling of heavy internal machining tools.

Efficient, reliable performance

Thanks to innovative in-process measurements, complex measuring tasks can be mastered with simple programming. This enables maximum manufacturing precision to be achieved with the tightest dimensional and positional tolerances. Analyses can be carried out and measuring protocols can be created at any time.

Another key advantage can be found regarding the coolant pressure. Thanks to targeted chip breakage optimization and the use of high-pressure coolant (HPC) up to 150 bar, machining costs can be reduced. What’s more, ultra-high pressure coolant (UHPC) ensures greater efficiency, lower tool costs, and improved process reliability during machining.

Workpiece transfer is also optimal with the M70-G MILLTURN counter spindle machine. The counter spindle with tailstock and synchronous spindle function combined with the powerful motor spindle and drive ensure reliable machining processes and maximum machining performance.

Intelligent tool management makes operation even easier, offering convenient software functions, straightforward and logical menu navigation, and automatic tool correctors converted by the control system to ensure efficient operation.
