WILLEMIN 408S2 VERTICAL MACHINING CENTER

Technical Description

The Willemin 408S2 is a compact, ultra-high precision 5-axis vertical machining center designed for complex prismatic parts within a work envelope of approximately X: 9.84", Y: 7.87", and Z: 11.81". It features a powerful 11.2 kW vertical spindle with HSK E40 tool interface, delivering speeds up to 30,000 RPM with rapid acceleration (0 to 30,000 RPM in 0.8 seconds), suitable for high-speed milling and fine finishing. The machine’s five-axis simultaneous control enables intricate multi-process milling and optional turning on the C axis up to 4,000 RPM, facilitated by a high-precision dual direct-drive dividers offering angular positioning resolution down to 0.0001°. Equipped with a 24-station automatic tool changer (ATC), it allows for efficient machining flexibility and reduced cycle times. The integrated FANUC 31i-A5 CNC control provides advanced nano-resolution servo control for nanometer-level positioning accuracy, multi-axis simultaneous interpolation, and optimized tool path smoothing, supporting up to 5 simultaneous controlled axes and up to 26 axes in total. The system ensures high reliability with extensive diagnostic and maintenance features suited for complex, precision components. The 408S2 supports programmable coolant through spindle (up to 80 bar), rapid linear axis accelerations (up to 8 m/s²), and fast tool changes (~0.8 seconds), making it highly productive for aerospace, medical, and mold industries requiring exceptional accuracy and finish quality in small to medium-sized parts.
