FAQ | Custom Turn-Mill Service Aluminum
Q1: What aluminum alloys can you process for turn-mill parts?
A: Mainly 6061-T6, 6063, 7075, 5052 aluminum. We can machine other aluminum grades per your drawing specification. Material test report (MTR) is available.
Q2: What tolerance can your turn-mill machine achieve?
A: Standard tolerance ±0.02 mm. Critical features such as concentricity, runout and thread fit can reach ±0.005 mm. We offer CMM inspection for key dimensions.
Q3: What parts are suitable for aluminum turn-mill machining?
A: Rotary & complex combined parts: precision shafts, flanged adapters, threaded sleeves, bushing, connector shells, servo fittings, sensor housings, robotic pin joints and automation fasteners.
Q4: What files do you accept for quotation?
A: STEP, IGES, X_T, SolidWorks, PDF engineering drawings. Our engineering team will provide DFM feedback before production.
Q5: What is your MOQ?
A: No strict MOQ. We support 1pc prototype, small batch trial run and mass production.
Q6: What is the lead time?
A: Prototype: 3–7 working days. Small batch: 7–15 working days. Mass production lead time depends on quantity and part complexity.
Q7: What surface finishes are available?
A: Raw machined finish, sandblasting, clear anodizing, black anodizing, hard anodizing, chromate conversion, laser marking.
Q8: What are the advantages of turn-mill over separate turning + milling?
A: Completed in one clamping, eliminates re-clamping alignment error, better concentricity & runout, shorter lead time and more stable consistency for complex rotary parts.
Q9: Can you add internal / external threads, grooves, O-ring seats and flat cuts?
A: Yes. We can integrate threads, snap grooves, O-ring grooves, flat milling, cross holes and cutouts in one turn-mill cycle.
Q10: What quality documents can you provide?
A: MTR, FAI first article inspection report, dimension inspection sheet, CMM report, anodizing certificate.
Q11: How about packaging & shipping?
A: Anti-scratch foam packaging for precision aluminum parts. We support DHL, FedEx, UPS and sea shipment for bulk orders.
