The new M70 Millturn, the latest addition to the
WFL Machine Technologies product family, is ideal for applications which require the ultimate in productivity and precision. It impresses with a sophisticated working area concept for working lengths of up to 8,000mm and for a swing diameter of up to 850mm. Thanks to the well-known and extensive 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 a wide range of additional options for highly productive deep-hole drilling processes and special technologies. With the capability to machine workpieces weighing up to 5,000kg, the machine is ideal for heavy-duty applications.
It features the familiar, reliable 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 set-up process can also take place in parallel to the machining time. This allows 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 which exceed the maximum dimensions of standard tools. Combining maximum precision with great flexibility, the M70 Millturn is ideal for customers with constantly changing requirements. Featuring large drilling and turning tools, high torque and high performance are extremely important in maximising the performance of the tools.
Complex workpiecesSpecially developed tools which have been designed to work seamlessly with the M70 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 that 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 types of magazine are available to provide automatic handling of heavy internal machining tools. These innovative tool solutions enable users to maximise the machine’s full performance potential.
Thanks to innovative in-process measurements, complex measuring tasks can be mastered with simple programming. This enables maximum manufacturing precision to also be achieved with the tightest dimensional and positional tolerances. Analyses can be carried out and measuring protocols can be created at any time.

Thanks to targeted chip breakage optimisation and the use of high-pressure coolant (HPC) of up to 150bar, the machining costs can be noticeably reduced. What is more, ultra-high pressure coolant (UHPC) ensures even 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 a drive ensure reliable machining processes and maximum machining performance. Intelligent tool management makes operation even easier. It offers convenient software functions, straightforward and logical menu navigation along with automatic tool correctors, which are automatically converted by the control system and ensure efficient operation.
