Your CNC Machining Queries Addressed
Discover comprehensive responses to frequently asked questions about our CNC machining services for aluminium projects. Explore our expertise and make an informed decision.
What is the standard tolerance for CNC-machined aluminum die cast parts?
We achieve ±0.01 mm tolerance across critical dimensions. For flatness, we maintain ≤0.05 mm per 100 mm depending on part geometry.
Can you provide post-machining surface finishes like anodizing or powder coating?
Yes. We offer anodizing, powder coating, polishing, and sandblasting after CNC machining. Surface finish Ra can reach ≤1.6μm depending on process.
How fast can I receive CNC-machined aluminum samples?
Samples are typically delivered within 7–12 working days after final drawing confirmation. For repeat models, we can shorten lead time to 3–5 days.
Do you support small batch CNC machining orders?
Absolutely. We accept quantities as low as 50 pcs for prototypes or pilot runs, and scale up to 100,000 pcs for mass production.
What materials do you commonly machine?
Mostly ADC12, A380, and custom aluminum casting alloys. For hybrid parts, we also work with brass, zinc, and stainless inserts.
Can I send you a 3D STEP file for quotation?
Yes, we support .STEP, .IGES, .DWG, .STL, and PDF drawings. Once we receive your file, we quote within 24 hours.
What types of CNC machines do you use?
We use 3-axis and 5-axis CNC machining centers, plus turning, tapping, and drilling equipment. Equipment list is available upon request.
Can you machine inserts or add threads?
Yes. We can add threads, helicoils, press-fit brass inserts, or machine parting lines as needed.
Do you provide CMM inspection reports?
Yes. All CNC parts go through dimensional inspection and CMM reports are available upon request.
How do I place an order or request a quote?
Simply email us your drawing and part quantity. Our engineering team will respond within 1 working day with DFM suggestions and pricing.
