WILLEMIN 528S VERTICAL MACHINING CENTER

Technical Description

The WILLEMIN 528S is a precision 5-axis simultaneous vertical machining center engineered for high-precision manufacturing of complex components in aerospace, automotive, and precision engineering industries. This machine accommodates workpieces within a maximum cube dimension of 350 mm per side, delivering superior surface finishes required for demanding applications. The machining center features linear travel axes of 800mm (X), 500mm (Y), and 630mm (Z), enabling flexible part positioning and accessibility. Equipped with a 15 kW spindle motor operating at 8,000 RPM with an HSK-A63 interface and 260 Nm torque, the 528S delivers reliable cutting performance across diverse materials. The swiveling spindle design provides complete 360° angular movement, facilitating simultaneous 5-axis machining without part repositioning, significantly reducing cycle times and improving productivity. The machine incorporates a high-precision Fanuc 31i-A5 CNC control system, enabling complex part programming and real-time machining optimization. Standard equipment includes a 24-position pickup-type tool magazine with optional capacity for 72 or 180 tools, coupled with a 5-second tool change time for enhanced flexibility. Advanced features include high-pressure coolant delivery at 80 bar, tool breakage detection, and programmable central coolant systems. The compact construction minimizes footprint while maintaining rigid machine base geometry, ensuring dimensional accuracy and repeatability. Optional configurations support increased spindle speeds of 12,000 or 20,000 RPM, cartesian tool magazines, and integrated automation systems for palletizing and part handling, making the 528S adaptable to diverse production requirements.
