5-axis machining center Go9

verticalfor steelfor aluminum

Overview
The Go9 is a 5-axis gantry machining centre engineered for high-speed milling of complex parts in steel, hardened steel, aluminium and titanium. Single-piece cast-iron U-frame gantry provides high rigidity and thermal stability. Compact footprint with no special foundation required and 24 tonnes of damping mass. Direct torque motors on A and C axes and active thermal control across the kinematic chain make the Go9 suited to mold shops, aerospace suppliers and automotive die manufacturers.

Key features

• Full Cast Iron Structure
  Single-piece U-frame base (24 t). No special foundation required. High thermal stability and vibration damping.
• Torque Motor Driven A and C Axes
  Backlash-free motion with direct encoders. Two motors on the A-axis cradle for maximum rigidity. Active cooling on all motors.
• Active Thermal Control
  Dedicated chiller for XYZ ball screws and for A and C direct motors. Refrigerated spindle with independent chiller to prevent thermal elongation.
• High-Speed Ball Screw System
  C3 class, preloaded, coolant-through ball screws on XYZ. Gantry Y axis with dual motors and dual optical scale for symmetric drive.

Applications

• Plastic Injection Molds: Machining of steel and hardened steel for complex, high-precision mold components used in automotive and optical lens production.
• Forging Dies: Hardened-steel dies for hot forging applications in automotive and industrial sectors.
• Aerospace: Brackets, rotating parts for jet engines and structural components in aluminium and titanium.
