Milling in hardened steel
Line shape of the profile 0.01
Perpendicularity 0.01

Part of the Month July 2016

Technology: Precision milling

Precision machining center:

Task:

  • Milling of a 90 mm long profile in hardened steel
  • Perpendicularity to the surface 0.01
  • Line shape of the profile 0.01 mm -> because of using the C-axis, Z must be stable within 5 microns during the entire milling process

Procedure:

  • Programming of tool tracks in a way that possible tool wear is not visible on the surface
  • Selection of the optimal step size for fulfilling the surface requirements in the shortest possible turnaround time
  • Determining the tool position behavior with a pre-process
  • Iterative procedure: milling, measuring, milling, ...

Result:

  • Because of the excellent reproducibility of the KERN Pyramid Nano, the gauge block could be achieved by iteration milling. Each correction was imported successfully, directly from the measuring machine results

Part size:

  • 110 mm
