  • Powerful BBT 40 spindle with speeds up to 10,000 rpm
  • High table load capacity of 1,500 kg allows machining of large, heavy workpieces
  • Short tool changing times and 30 stations (optionally expandable to 40 stations) for increased productivity, high flexibility, and increased spindle up-time per shift

Machine Design

  • Heavily ribbed machine frame with extra low center of gravity
  • A major focus during development of this machine was a space-saving design
  • The Lupus Series features linear guides on X, Y and Z to ensure high accuracy made possible by lower friction and higher dynamics
  • 40 mm preloaded ball screws combined with a digital drive package provide a rigid table guide and high torque at maximum dynamics


  • BBT 40 spindle with dual tool clamping ensures very secure seating of clamped tools in the spindle - low vibrations result in increased surface quality
  • The spindle runs on 4 bearings for excellent absorption and dissipation of forces generated during machining - resulting in high surface quality
  • The Lupus Series features 3 types of spindles (belt / built-in / gear) with various speeds to allow optimum customization for specific process requirements

Tool changer

  • Dual-arm tool changer with 30 stations ensures adequate flexibility and capacity for every day production needs (optionally with 40 stations)
  • Short changing times (1.3 seconds tool-to-tool and 3.9 seconds chip-to-chip) increase spindle up-time and machine output
