SURFACE FINISH

Surface Treatment Processes

One-stop surface treatment, balancing appearance, protection and function; delivered ready to assembly standard.

Anodizing

Surface-hardened and colored aluminum; corrosion- and wear-resistant, multiple colors; the top choice for consumer-electronics housings.

Sandblasting / Brushed Finish

Uniform matte or brushed texture that hides tool marks and improves feel and appearance.

Plating / Passivation

Nickel/chrome plating improves conductivity and corrosion resistance; stainless passivation boosts corrosion resistance and cleanliness.

Heat Treatment

Quenching, tempering and age hardening raise hardness and mechanical properties to meet load-bearing part requirements.

FAQ

FAQ

Questions you may have about CNC machining services.

How is CNC machining quoted? How to get a price quickly?+

The cost is mainly determined by material, machining hours, precision requirements, post-processing, and quantity. Send STEP/IGS drawings (with 2D engineering drawings noting tolerances) to the contact page or email; engineers complete the DFM review within 2 hours and reply with a formal quotation; batch parts enjoy tiered pricing.

What is the typical lead time? Can it be expedited?+

Conventional functional prototypes 3–5 days, precision parts and surface-treated parts 5–8 days, batch parts scheduled by quantity. Rush channel supported; simple aluminum parts ship in as fast as 48 hours with SF Express next-day delivery.

How high can the accuracy and surface finish be?+

Standard dimensional tolerance ±0.05 mm; precision parts can reach ±0.01 mm, and ultra-precision critical dimensions ±0.005 mm; surface roughness standard Ra1.6, finish machining can reach mirror-grade Ra0.4, further improved with polishing/electropolishing.

What is the minimum order quantity? Can you make just 1 piece?+

Supports orders from a single piece, with no minimum order quantity limit. Single pieces suit prototype verification; for batch parts we optimize fixtures and toolpaths to lower unit price—the higher the quantity, the better the unit price.

Which file formats are supported? Can it be done with only a 2D drawing and no 3D model? +

STEP / IGS / X_T 3D formats are recommended, with 2D engineering drawings attached (marking key tolerances, threads, surface treatment requirements). Parts can be machined from 2D drawings alone; our engineers can model on your behalf, and production is scheduled after confirmation.

Will an inspection report be provided? How is quality ensured?+

First-piece inspection is standard; batch parts are sampled by AQL or fully inspected; we can provide CMM inspection reports, material certificates and shipment inspection reports (COC). Critical dimensions are 100% traceable, and custom inspection standards per drawing are supported.

Upload drawings for fast precision part delivery

Whether a complex curved-surface prototype, a batch of precision structural parts, or a hardened-steel mold insert, send your 3D drawing and requirements and our engineers complete DFM review and quotation within 2 hours.
