Laser Cutting small parts
Laser Cutting small parts
(OP)
I am looking for a recommendation for a material.
Small part, Largest dimension is .22mm smallest is .009mm
Tolerances are +- .0005mm
Environment is hydraulic fluid, pressure to 2000psi, temperature to 140°F.
Two flat surfaces of this material will be moving relative to each other.
I have been thinking either graphite or Teflon.
I was hoping to be able to use a laser to cut some of the features.

Teflon is generally not a good structural material for sustained loads since it tends to cold flow.
For a tiny part with extremely tight tolerances, you might consider using photo etched metal. It is extremely precise and produces no stress in the finished part.

This material is dimensionally stable and strong enough to support fine features.
