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.
