Q:How fast can I receive a CNC prototype?

A:Lead times vary depending on part complexity, material availability, and finishing requirements, but generally:

· Simple prototypes: 1–3 business days

· Complex or multi-part projects: 5–10 business days

Expedited service is often available.

Q:What design files do I need to provide?

A：To get started, you should submit:

· 3D CAD files (preferably in STEP, IGES, or STL format)

· 2D drawings (PDF or DWG) if specific tolerances, threads, or surface finishes are required

Q:Can you handle tight tolerances?

A:Yes. CNC machining is ideal for achieving tight tolerances, typically within:

· ±0.005" (±0.127 mm) standard

· Tighter tolerances available upon request (e.g., ±0.001" or better)

Q:Is CNC prototyping suitable for functional testing?

A:Yes. CNC prototypes are made from real engineering-grade materials, making them ideal for functional testing, fit checks, and mechanical evaluations.

Q:Do you offer low-volume production in addition to prototypes?

A:Yes. Many CNC services provide bridge production or low-volume manufacturing, ideal for quantities from 1 to several hundred units.

Q:Is my design confidential?

A:Yes. Reputable CNC prototype services always sign Non-Disclosure Agreements (NDAs) and treat your files and intellectual property with full confidentiality.
