CNC tool grinding machine Evolution

CNC TOOL GRINDING MACHINE TTB EVOLUTION

5 OR 6 AXES - PRECISION AT ITS BEST

TTB-Highest precision quality without compromise

  • Tools in the diameter range from Ø 0.02 to 12 mm in optimum quality
  • Consistent accuracy even after many years, thanks to TTB own developed axes drive mechanical system
  • Spindle revolver with 4 grinding spindles repeat positioning precision < 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.
