Frequently Asked Questions
What tolerances can you achieve with CNC machining?
Our standard machining capabilities achieve ±0.001" tolerances, with specialized processes capable of ±0.0001" for critical dimensions. Actual achievable tolerances depend on part geometry, material, and other factors which we evaluate during the quoting process.
What file formats do you accept for quoting?
We prefer 3D CAD files in STEP, IGES, or Parasolid formats along with 2D drawings in PDF format that include all critical dimensions and GD&T requirements. We can work with other formats if needed.
How do you ensure parts meet tight tolerance requirements?
We use a combination of precision CNC equipment, temperature-controlled machining environments, advanced metrology equipment (including CMMs), and rigorous process controls to ensure parts meet specifications. First article inspection and statistical process control are standard for close tolerance work.
What is your typical lead time for close tolerance machining?
Standard lead times are 2-4 weeks depending on complexity and volume. Rush services are available for critical projects, with some parts deliverable in as little as 5 business days. We'll provide a firm delivery commitment with your quote.
Do you provide material certifications?
Yes, we provide full material certifications (mill test reports) with all precision machined parts, along with inspection reports verifying dimensional accuracy and surface finish requirements.
