Kitaoka Industrial, Inc.

Ultra-precision machining of monocrystalline diamond

Kitaoka Industrial, Inc. is specialized in the machining of difficult to cut hard and ultra-hard materials such as monocrystalline diamond, sapphire, silicon carbide, and gallium nitride.

In addition to that, we can also process composite materials such as CFRP (carbon fiber composite material).

We work to specification and can help our customers with the optimization of the design of tools made from these hard to process materials.

Monocrystalline diamond movement

  • We provide movements with high-precision monocrystalline diamond processing technology

  • We provide escape wheel and anchor by utilizing the wear resistance of monocrystalline diamond

  • Utilizing the non-magnetism of monocrystalline diamond, we can provide parts that do not rust and are not affected by magnetic fields

  • Monocrystaline diamond gears do not require lubricationg oil

  • We provide tools for microfabrication of monocrystalline diamond drills and endmills

Recently we have started working on biomimetic technology using monocrystalline diamond tools
