Surface Finishes
As-Machined (Fine)
High-quality machined finish direct from simultaneous 5-axis toolpaths. Ra 0.8μm achievable on contoured surfaces with ball-nose finishing passes. Fewer setups mean fewer witness lines and blend mismatches.
Anodizing (Type II / Type III)
Electrochemical oxide layer for aluminum parts. Type II: 5-25μm, custom colors. Type III (hard coat): 25-150μm for extreme wear resistance. Ideal for aerospace and consumer-facing components.
Passivation
Chemical treatment for stainless steel and titanium removing free iron and enhancing corrosion resistance. Critical for medical and marine applications. No dimensional change.
Polishing (Mirror/Satin)
Mechanical polishing of complex contoured surfaces. Mirror polish: Ra ≤ 0.1μm. Ideal for medical implants, optical housings, and premium consumer products.
Bead Blasting
Uniform matte texture that hides minor witness marks on multi-face parts. Glass bead or aluminum oxide media. Achieves consistent Ra 1.6μm - 3.2μm cosmetic finish.
Electroplating (Nickel/Chrome)
Metallic coating for enhanced wear resistance and appearance. Uniform coverage on complex geometries verified by thickness mapping. Thickness: 5-25 microns.
Design for Manufacturing (DFM)
- Orient complex features so they can be reached in a single 5-axis setup — this is where the cost and accuracy advantage comes from
- Avoid deep narrow slots that limit tool length and tilt angle; keep depth-to-width ratios below 6:1 even on 5-axis
- Use 5-axis machining to reduce fixtures: fewer clamping operations means less clamp distortion on thin-wall parts
- Keep wall thickness consistent on contoured surfaces to prevent vibration and maintain surface finish quality
- Design fillet radii slightly larger than standard tool radii to allow smooth flowing toolpaths and better finishes
- Specify true position and profile tolerances only on functional features — blanket tight tolerances drive cost
- For impellers and blades, provide the 3D model as the master definition; 2D drawings cannot fully define complex surfaces
- Consider tool access cones: features requiring more than 110° of tilt may need special fixtures or a second setup
- Leave 0.2-0.5mm finishing stock callouts to us — we optimize roughing and finishing strategies internally
- Upload STEP/IGES files for a free DFM report within 24 hours covering setup strategy, tool access, and cost optimization

FAQ
1. What is the minimum order quantity (MOQ) for 5-axis CNC machining?
Our 5-axis CNC machining MOQ is just 1 piece. Complex parts often start as single prototypes for design validation before moving to production quantities. Whether you need one impeller or 10,000 production parts, we apply the same machining strategy development and quality verification.
2. What tolerances can you achieve with 5-axis machining?
Our standard 5-axis tolerance is ±0.02mm, with ±0.01mm achievable on critical features. Angular positioning accuracy is ±0.01°. Because the part is machined in a single setup, we eliminate re-fixturing errors — geometric relationships between faces (true position, profile, concentricity) are typically held to 0.02mm, better than multi-setup 3-axis machining can achieve.
3. When should I choose 5-axis instead of 3-axis CNC machining?
Choose 5-axis when: your part has complex 3D contours requiring simultaneous multi-face machining; you need to reduce setups for better accuracy; the part has deep cavities, undercuts, or compound angles that 3-axis tools cannot reach; or you are in aerospace, medical, or high-precision tooling. 3-axis remains more economical for flat parts, simple pockets, and through holes. If unsure, send us your STEP file — our engineers will recommend the most cost-effective approach in the free DFM report.
4. What materials can you machine on 5-axis centers?
Aluminum alloys (6061, 7075, 2024), titanium (Grade 2, Grade 5 Ti-6Al-4V), stainless steel (303, 304, 316L, 17-4 PH), tool steels (D2, H13), brass, copper, and engineering plastics (PEEK, POM, PC). For aerospace and medical applications, we source certified material with full mill traceability. Titanium and superalloys are machined with dedicated tooling and optimized speeds.
5. What is the typical lead time for 5-axis machined parts?
Prototypes: 3-7 working days depending on complexity. Production runs: 7-20 working days depending on quantity and finishing requirements. Custom fixtures for production add 1-2 weeks upfront but reduce per-part cost significantly. Every quote includes a confirmed delivery date, and our free DFM review is completed within 24 hours of receiving CAD files.
6. Do you provide free DFM analysis for 5-axis parts?
Yes. Upload your STEP/IGES file and we return a free DFM report within 24 hours. For 5-axis parts, the report covers setup orientation strategy, tool access analysis (tilt angle limits), thin-wall risk zones, fixture requirements, and cost optimization opportunities. This engineering review frequently identifies changes that cut machining cost 15-30% before any metal is cut.
7. What CAD file formats do you accept?
We accept STEP (.stp/.step), IGES (.igs), Parasolid (.x_t), SolidWorks (.sldprt), STL, DXF, DWG, and PDF drawings. For 5-axis contoured parts, the 3D model is the master definition — STEP files are strongly preferred. 2D drawings alone cannot fully define complex freeform surfaces.
8. What surface finishes are available?
Fine as-machined finish (Ra 0.8μm on contours), anodizing (Type II/III for aluminum), passivation (stainless and titanium), polishing (mirror to Ra ≤ 0.1μm), bead blasting, and electroplating (nickel/chrome). Because 5-axis parts are machined in one setup, cosmetic surfaces have fewer blend lines and finish more uniformly.
9. How is pricing calculated for 5-axis machined parts?
Price = Material cost + Machine time (setup + programming + machining) + Surface finishing + Inspection. 5-axis programming is more involved than 3-axis, but single-setup machining often makes complex parts cheaper overall — fewer fixtures, less handling, lower scrap risk. We provide detailed quotations within 24 hours, and higher quantities amortize programming cost significantly.
10. Can you provide samples before mass production?
Yes. We machine first articles on the same 5-axis machines and verify them by CMM against your 3D model before production release. Prototype quantities of 1-10 pieces are our specialty — many customers validate the design with machined prototypes, then move directly to production with the proven program and setup.
11. Do you offer third-party inspection (SGS / Bureau Veritas)?
Yes. On request we can arrange independent third-party inspection by SGS or Bureau Veritas at any stage - before shipment, during production, or on incoming material. You receive a full independent inspection report (dimensional CMM measurement, material verification, and appearance/surface check) so parts are verified by a neutral party before leaving our facility.
12. How do you ensure quality on complex 5-axis parts?
Our quality process: calibrated 5-axis CMM with contoured surface scanning verified against the 3D model, first-article inspection before production release, in-process checks of critical angles and dimensions, and a full dimensional report with every batch. For production orders, we run capability studies (Cpk ≥ 1.33) on critical dimensions and share statistical data on request.
13. Do you sign NDA before reviewing design files?
Yes, we sign NDA before quotation, not just before production. 5-axis parts are frequently aerospace, medical, or defense-related where IP protection is critical. Your CAD files, specifications, and business information are treated as confidential assets. NDA signing is our standard practice.
14. Do you ship internationally?
Yes, we ship worldwide via DHL, FedEx, UPS, and sea freight. Precision parts are packed with anti-rust protection, foam-lined boxes, and vacuum sealing where required. Every shipment includes packing list, Certificate of Origin, and commercial invoice. Air express to US/Europe typically takes 3-7 days.
15. Can you handle both prototyping and production volumes?
Yes. Prototype phase: 1-100 pieces with rapid turnaround and design feedback. Production phase: custom fixtures, optimized cycle times, and process validation for 100-10,000+ piece runs. The 5-axis program developed for your prototype transfers directly to production, so there is no re-engineering risk when you scale.
16. Can you machine parts that also need turning, EDM, or grinding?
Yes. Our 5-axis machining integrates with in-house CNC turning, wire EDM, sinker EDM, and precision grinding. Complex parts requiring multiple processes are managed under one purchase order with a single quality plan — reducing your supplier management overhead and ensuring dimensional compatibility across operations.
