Optical Surface Quality

Since beginning of 2012 due to new develo­p­ments in drive and spindle technology extremely high surface qualities are achie­vable, which are compa­rable to such produced on ultra-precision machine tools (UP machines).


Produced with air bearing spindle on the machine

  • Precision +/- 1 µm
  • Surface quality Ra = 0.005 µm
