FAQ | Rapid Turn Mill Service Aluminum Anodized

Q1: What aluminum grades are available?

A: Regular aluminum alloys: 6061-T6, 6063, 7075, 5052. We can process other aluminum grades according to your drawing requirements. MTR material test reports are available upon request.

Q2: What tolerance can you achieve?

A: Standard tolerance ±0.02 mm. Critical mating features, concentricity and runout can reach ±0.005 mm. We will pre-compensate machining dimensions to offset the anodizing coating thickness to meet your final tolerance target. CMM inspection for key dimensions is supported.

Q3: What anodizing finishes do you provide?

A: Clear anodizing, black anodizing and hard anodizing. Hard anodizing features higher surface hardness and better wear resistance for high-load functional components.

Q4: What typical parts fit this rapid turn-mill service?

A: Precision shafts, flanged adapters, threaded sleeves, O-ring groove fittings, sensor housings, servo connectors, robotic joint pins and automation mounting parts.

Q5: What drawing formats do you accept for fast quotation?

A: STEP, IGES, X_T, SolidWorks and PDF engineering drawings. Our engineering team will send DFM feedback quickly.

Q6: What is your lead time for this rapid service?

A: Prototype without anodizing: 2–5 working days. Prototype / small batch including anodizing: 7–12 working days. The exact lead time depends on part complexity and anodizing type.

Q7: Do you have MOQ?

A: No strict MOQ. We support 1pc urgent prototype, low-volume small batches and pre-production orders.

Q8: Can you process threads, cross holes, O-ring grooves and flat milling in one setup?

A: Yes. Turn-milling integrates turning, milling, cross drilling, grooving and threading in one clamping, saving production time and improving precision.

Q9: What quality documents can you provide?

A: Material test report (MTR), FAI first article inspection report, dimension inspection sheet, CMM inspection report and anodizing certificate.

Q10: How do you pack anodized aluminum parts?

A: Each part is individually packed with anti-scratch foam to protect the anodized surface. We support DHL, FedEx, UPS and sea freight for different shipping needs.
