FAQ

Frequently Asked Questions

Quick answers to common questions about our precision CNC machining services.

Send us your drawings or CAD files with the material, quantity, tolerances, and surface finish requirements. Our team will review the project and provide a quotation.

We support prototypes, one-off parts, low-volume production, and repeat orders. There is no strict minimum order quantity.

Depending on the material, geometry, size, and critical features, tolerances down to ±0.005 mm may be achievable. Final tolerances are confirmed during drawing review.

We machine aluminum, stainless steel, tool steel, brass, copper, titanium, and engineering plastics including POM, PC, PMMA, ABS, PEEK, and PA.

Available finishes include anodizing, bead blasting, polishing, nickel plating, and other finishing options based on your part requirements.

Lead time depends on part complexity, quantity, material, tolerances, and surface finishing requirements. Estimated production time is confirmed with your quotation.
