CNC Prototype Machining FAQ
What is CNC prototype machining?
CNC prototype machining is the process of manufacturing custom prototype parts using CNC mills and lathes from CAD designs. It is the fastest method for manufacturing prototype parts with complex geometry, tight tolerances, and functional requirements. Prototypes are manufactured in 3–10 days, enabling rapid design iteration and validation.
What is the difference between prototype machining and production machining?
Prototype machining prioritizes speed, design flexibility, and short turnaround. Single units are manufactured without worrying about tooling cost amortization. Production machining optimizes for unit cost and volume efficiency through setup amortization and process optimization. Prototyping is for design validation; production is for scaled manufacturing.
How long does CNC prototype machining take?
Quotes are provided in 2 business days. Manufacturing typically takes 3–10 days depending on part complexity: simple parts 3–5 days, medium complexity 5–7 days, complex 5-axis parts 7–10 days. Express service is available for urgent prototypes.
What file formats are accepted for prototype machining?
We accept STEP, IGES, STL, Solidworks, DWG, PDF, and other CAD formats. Files must include dimensions, tolerances, material specification, and surface finish. If you have sketches or concept drawings, our team can convert them to detailed designs.
Can I make design changes between prototype iterations?
Yes. Prototype machining is designed for rapid iteration. Changes between iterations are accommodated quickly with no retooling or additional setup. This enables rapid design refinement based on prototype testing and feedback.
What tolerances can you hold on prototype parts?
Standard CNC machining holds ±0.05mm. High-precision prototypes hold ±0.01mm. Critical features with CMM verification can achieve ±0.005mm. Specify tolerance requirements on your drawing — tighter tolerances increase cost and turnaround.
