2011 HAAS VR11 VERTICAL MACHINING CENTER

Technical Description

The 2011 Haas VR11 is a 5-axis gantry-style vertical machining center designed for large-format 5-axis contouring, aerospace structural components, mold surfaces, and complex multi-sided part machining. The VR-11 features a fixed gantry column with a tilting/rotating spindle head that provides simultaneous 5-axis motion across B and C axes, enabling full 5-sided machining without workpiece repositioning. Axis travels span 120 inches in X, 40 inches in Y, and 30 inches in Z, with a 120-by-28-inch table accommodating long structural workpieces typical of aerospace and energy sector applications. The legacy VR-11 spindle is a CAT40 unit rated at approximately 30 HP with a maximum speed of 10,000 RPM, providing strong torque for structural machining and heavy contouring. The extended X-axis travel of 120 inches makes the VR-11 particularly suited to fuselage panels, wing ribs, long extrusions, and large mold surfaces where a conventional VMC's work envelope would be insufficient. The machine's rigid gantry frame and high-mass construction minimize deflection and vibration during simultaneous 5-axis interpolation, maintaining dimensional accuracy across the full travel range. A high-capacity tool changer supports extended unmanned machining sequences across multiple operations and part features. The Haas CNC control provides full 5-axis G-code support with simultaneous 5-axis interpolation capability. At approximately 32,500 pounds, the VR-11 provides the structural stability required for precision 5-axis work on large components. It is well suited to aerospace prime contractors, defense manufacturers, and heavy tooling shops requiring large-format 5-axis capability.
