Your advantages at a glance

  • Long travel range and large degrees of freedom for machining
  • Inherently rigid, vibration-damping machine bed in Monolith™ design
  • Strongly ribbed, torsionally rigid column
  • Compact precision roller guideways for highest machining accuracy
  • Speeds of up to 6,000 min-1; power of up to 34 kW
  • Comprehensive equipment for high flexibility
  • Working area that is easy to access

Monolith™ machine bed

in sandwich design with a welded, strongly ribbed upper section, fiber-reinforced high-performance concrete and a steel floor panel with special damping elements. Developed and implemented successfully in roll grinding machines hundreds of times by the sister company Maschinenfabrik Herkules:

  • Torsionally rigid and thermostable
  • Effective damping of vibrations
  • Set-up directly on the floor and small footprint

Extremely stiff, welded steel column

  • Strong inner ribbing that prevents bending and torsional deformation
  • Preloaded linear compact roller guides and spaciously dimensioned, preloaded ball screw drives

Headstock and boring spindle

  • Produced in-house to ensure highest quality
  • Low wear and high machining quality

Rotary clamping table

  • Precise and backlash-free positioning of the workpieces

Automatic tool change

  • Tool magazine with up to 120 tools
  • Tool gripper SK 50 or HSK 100, others on request
  • Changing cycles for heavy tools, tool taper cleaning

Compact cooling units 

  • External cooling at the headstock with 80 l / 8 bar
  • Internal cooling through the middle of the boring spindle / optionally through the milling head spindle with up to 70 bar
  • Paper band filter and coolant circulation with timer switch
  • Extraction device / connection for central extraction device

Work area protection / CE-approved operation

  • Operator panel swivelling into working area, option: angled desk design
  • Full enclosure

Process optimization
