CNC-Grinding Center TTB Evolution


5 axes - Highest Precision in Tool Grinding

 

Highest precision in tool grinding

TTB-Highest Precision Quality without compromise

  • Tools in the diameter range from 14 to 0.02 mm in optimum quality
  • Consistent accuracy even after many years thanks to unique TTB mechanical axes drive system.
  • Revolver with 4 or 5 grinding spindles and repeatability <0.3µm
  • Short changeover times because of the use of modular components
  • High mechanical reliability and extremely low downtime
  • Optimum TCO (Total Cost of Ownership) thanks to reduced price of the machine and low maintenance costs.

 

Tool data

  • Min. tool diameter Ø 0.02 mm
  • Max tool diameter Ø 14 mm
  • Max grind length 100 mm
  • Resharpening Ø 3 – 25 mm



Technical features

  • Spindle change-over : repeatability less than 0.3 µm axial and radial and in less than 4 seconds
  • Each spindle can mount up to 3 grinding wheels
  • Backlash free linear axes with unique TTB axis drive system
  • High-precision drive spindles, hydrodynamic lubrication and hydraulic backlash-free compensation (preload)
  • Rotary axis V: backlash-free with hydraulic compensation (preload)
  • All axes X-Y-Z-V-U with direct high-resolution measuring systems - glass scales and direct encoders (+/- 0.01µm or +/- 2“)
  • Multi-pallet loader from 2 to 4 pallets for high capacity
  • Pallets for diameters from 1 to 16mm and up to 814 workpieces
  • NUM control with NUMROTOplus® software
  • Extensive accessories and special units for flexible expansion options
