Frequently Asked Questions

• What file formats do you accept?

  • We commonly work with STEP, IGES, DXF, and PDF drawings.

• Can you handle tight tolerances?

  • Yes. Typical tolerances range from ±0.001" to ±0.005" depending on material and geometry.

• Do you handle prototypes?

  • While we specialize in long run production machining, depending on the part or project we can provide short run prototype machining on a case by case basis.​
