Ceramics Machining

ColdQuanta has dedicated manufacturing equipment to fabricate complex structures in silicon, sapphire, and scientific glasses into UHV chambers and components. We specialize in fabricating parts from materials that are usually difficult to find shops willing to machine. With the use of vertical CNC milling machines, our unique process enables us to create non-conventional geometry within brittle materials.

Typical Materials:

  • Silicon
  • Pyrex
  • Fused Silica
  • Alumina
  • Sapphire


  • Drilling
  • Core drilling
  • Trepanning
  • Profiling
  • Chamfering
  • Pocketing
  • Slotting
  • Standard tolerances of .005”.
  • Typical edge chipping ≤.01”.
  • Standard surface finish of (???µm).
  • Ability to achieve surface finish ≤ (???µm)
