CNC milling machine M7 series

horizontalfor aeronautics

Overview
The M70 MILLTURN is a CNC multitasking turning‑milling center built on the modular WFL system. Its machine concept minimises distances between workpiece, tool and guideways while maximising distances between guideway pairs to ensure optimal stability and geometry. The front-loading tool magazine provides compact, stable storage with safe access.

Highlights at a glance

• Modular tool interfaces designed for long-term accuracy and rigidity.
• Standard tool interface engineered for high feed forces.
• Capable of highly productive deep-hole drilling and a range of special machining technologies.
• Prism tool system enables tools exceeding standard tool dimensions.
• Use of solid prism holders and automatic cutting-head change with the WFL system boring bar.
• Two magazine variants (various capacities up to 200 positions).
