CNC Machining


As a solutions provider for machining hard and brittle materials,

Bullen offers CNC machining as one of our options for various challenges, such as drilling, milling, and grinding materials including:

  • Glass
  • Ceramics
  • Silicon carbide
  • Sapphire
  • Quartz
  • Zirconia

We can achieve and provide these solutions because of our extensive experience with hard and brittle materials, our state-of-the-art equipment, our custom tooling, and our programming.

We use this combination to machine thru-holes, counterbores, blind cuts, cavities, slots, and odd-shaped holes, in addition to both OD and ID work.

  • Typical feature size, location, and depth tolerance: +/- 12 µm (contact R&D for tighter specifications)
  • Smallest feature: on ID, 600 µm; on OD, 300 µm (Smaller features can be achieved with special tooling.)
  • Depth/cavity cuts: 300 µm R max, minimum floor 250 µm (Thinner floor thickness can be achieved on a case-by-case basis.)
  • Can align to previously patterned, machined, or etched materials

When facing a challenge that requires CNC machining, Bullen is the solution.
