FAQ | Small Batch Turn Milling Parts Service Aluminum Anodized
Q1: What aluminum grades do you support for small batch turn-milling & anodizing?
A: 6061-T6, 6063, 7075 and 5052 aluminum are our regular options. Other aluminum alloys can be processed according to your drawing requirements. MTR material test reports are available on request.
Q2: What tolerance can you achieve for these anodized turn-mill parts?
A: Standard tolerance ±0.02 mm. Critical features like concentricity, runout and mating surfaces can reach ±0.005 mm. We can arrange CMM inspection for key dimensions.
Note: Anodizing adds a thin layer, we will compensate the machining size in advance to hit your final tolerance target.
Q3: What anodizing types are available?
A: Clear anodizing, black anodizing and hard anodizing. Hard anodizing offers higher hardness and better wear resistance for functional parts.
Q4: What typical parts fit this small batch turn-milling service?
A: Precision shafts, flanged adapters, threaded sleeves, O-ring groove fittings, sensor housings, servo connectors, robotic joint pins and automation mounting components.
Q5: What design files do you accept for quotation?
A: STEP, IGES, X_T, SolidWorks and PDF engineering drawings. Our engineering team will provide DFM feedback before machining.
Q6: What is your small batch range?
A: We support 1pc prototype, 5–200 pcs small batch orders. We also accept ramp-up orders for mass production transfer. No strict MOQ.
Q7: What is the lead time for small batch anodized aluminum turn-mill parts?
A: Prototype: 3–7 working days. Small batch (including anodizing): 10–18 working days. The exact lead time depends on part complexity and anodizing type.
Q8: Can you machine threads, cross holes, O-ring grooves and flat cuts on the same part?
A: Yes. Turn-milling completes turning, milling, cross drilling, grooving and threading in one setup.
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 protect the anodized surface during packaging?
A: Anti-scratch foam and individual compartment packaging. We avoid direct friction between finished anodized surfaces. We support DHL, FedEx, UPS and sea freight.
