Dispersion of individual values around the average values
Milling with maximum repeat accuracy
KERN Micro: long-term stability
5-axis precision milling

Part of the Month October 2015

Technology: 5-axis-precision milling
Milling with maximum repeat accuracy

Precision machining center:


  • Demonstration of the KERN Micro's long-term stability
  • Production of 6 parts: three parts in succession, 1h pause, then three more parts in succession


  • Analysis of 234 individual values
  • 95% of the measured values on all 6 parts are within a range of +/- 1,5 µm

Part size:

  • Ø Base: 120 mm
  • Height: 100 mm
