With 14+ years of expertise in micro-precision manufacturing, we specialize in advanced 5-axis CNC machining tailored for small-diameter components—down to 2mm turning diameter. Our technology integrates high-speed turning and multi-axis milling to solve the core challenges of small-part machining (vibration, deformation, low efficiency), serving global clients in electronics, medical, and automotive sectors. Whether for 2mm micro-shafts or complex small parts with integrated features, we deliver consistency and accuracy that exceed industry standards.
Our 5-axis machines (Haas UMC-500, DMG Mori NLX 2500) are equipped with specialized components to ensure stable machining of 2mm-diameter parts:
- Micro-Tooling Support: Uses ultra-precise tool holders (runout ≤0.0005mm) and carbide micro-tools (0.5mm minimum diameter) to avoid vibration during turning—critical for maintaining roundness ≤0.001mm on 2mm shafts.
- High-Speed Spindles: 30,000 RPM spindles with dynamic balance control reduce heat generation, preventing material deformation (e.g., for brass micro-pins, no surface oxidation or warping).
- Adaptive Cutting Technology: Real-time load monitoring adjusts cutting speed and feed rate for 2mm parts, reducing tool wear by 40% and ensuring consistent tolerance (±0.002mm) across batches.
For small parts requiring both turning and milling (e.g., a 2mm-diameter shaft with 0.3mm side holes and 0.2mm grooves), our 5-axis technology completes all processes in one setup:
- No Repositioning Errors: Eliminates the need to transfer parts between turning and milling machines, reducing alignment errors to ≤0.001mm—essential for parts like medical needle hubs (where 2mm shafts need precise lateral holes for fluid flow).
- Complex Feature Compatibility: Machines angled features (0–360°) on 2mm parts, such as 45° chamfers on connector terminals or 30° slots on micro-gear shafts, without secondary operations.
We tailor machining parameters to the unique properties of materials used in small-diameter applications:
- Metals: For brass/copper (electronic connectors), low-cutting-force strategies preserve electrical conductivity and surface smoothness (Ra ≤0.05μm). For 316L stainless steel (medical parts), high-pressure cooling (70 bar) prevents heat-induced corrosion.
- Plastics: For PEEK/POM (industrial micro-valves), temperature-controlled machining (20–25℃) avoids warping—critical for maintaining the precision of 0.1mm-wide grooves on 2mm plastic shafts.
- DFM Analysis: Provide 24-hour Design for Manufacturability feedback for small-diameter parts (e.g., optimizing 2mm shaft fillets to ≥0.1mm to avoid tool breakage).
- Prototype Validation: Produce 1–10 unit prototypes in 4–6 days to test fit and function, with adjustments to machining parameters if needed.
- Precision Inspection: Use Zeiss CMM (±0.0005mm accuracy) for dimensional testing, Taylor Hobson Form Talysurf for roundness/concentricity checks, and Mitutoyo SJ-210 for surface roughness measurement.
- Batch Consistency: 100% visual inspection for burrs; 25% sampling for dimensional tolerance to ensure all parts meet specs.
- Small Batches: 10–500 units for R&D or maintenance needs, with flexible scheduling.
- Bulk Orders: 10,000+ units/month via automated 5-axis cells, with robotic loading/unloading to maintain consistency.
