Sapphire Through-Hole Sidewall Machining

Workpiece

  • Sapphire
  • Hole: D2.5×0.8mm
  • Required Roughness Ra < 200nm

Challenges

  • Poor hole wall surface quality
  • Polishing time too long for mass production

Benefits

  • Hole wall roughness improved from by 85%, 293nm to 46nm
  • No need for polishing

Workpiece

Benefits

  • Nomex Honeycomb Contouring

Challenges

  • Uneven machined surface, severe burrs and excessive dust
  • Vulnerable to workpiece deformation, tearing and collapse due to compression
 
 
  • Burr reduction by 90%
  • Efficient 5-axis contouring of complicated shapes
  • Optional fully-closed protection and vacuum system against dust and explosion
