With over 12 years of expertise in high-precision machining, we specialize in 5-axis CNC solutions tailored for small-diameter components (down to 2mm turning diameter), serving electronics, automotive, medical, and industrial sectors. Our technology integrates turning and multi-axis milling to handle common application needs—from micro-fasteners to tiny sensor housings—delivering consistent accuracy and efficiency trusted by 200+ global clients, including mid-sized manufacturers and industrial equipment OEMs.
Our 5-axis CNC technology combines turning and multi-axis milling to solve the challenges of small-diameter common applications, offering three core advantages:
Equipped with high-speed precision spindles (30,000 RPM) and micro-tool holders (0.5mm minimum tool diameter), we achieve stable turning of components as small as 2mm—critical for common applications like electronic micro-pins (0.8mm pitch) or medical tiny shafts. The 5-axis structure eliminates "overhang vibration" (a common issue in 3-axis machining for small diameters), ensuring roundness ≤0.001mm and surface roughness Ra ≤0.05μm, avoiding post-processing rework.
For small parts requiring both turning and milling (e.g., a 2mm-diameter shaft with side holes and grooves), the 5-axis machine completes all processes in a single setup—no repositioning needed. This reduces setup errors to ±0.002mm, ensuring alignment between turned cylindrical surfaces and milled features (e.g., 0.3mm side holes on a 2mm shaft). For common industrial components like micro-valve cores, this integration cuts production time by 40% vs. traditional multi-machine processing.
We tailor machining parameters to materials widely used in common sectors:
- Metals: For brass/copper (electronic connectors), we use low-cutting-force strategies to avoid surface deformation, preserving conductivity. For 316L stainless steel (medical parts), high-speed cooling prevents heat-induced oxidation, ensuring biocompatibility.
- Plastics: For POM/PEEK (industrial small gears), temperature-controlled machining (25–30℃) prevents warping, critical for maintaining gear tooth precision (±0.003mm).
Our 5-axis machining serves high-demand common scenarios:
- Electronics: 2–5mm diameter connector pins (tolerance ±0.003mm) for PCB boards, ensuring stable signal transmission.
- Automotive: Tiny sensor shafts (2–8mm) for ABS systems, with concentricity ≤0.002mm to avoid measurement errors.
- Medical: 2–3mm diameter needle hubs (316L stainless steel), with smooth Ra ≤0.03μm surfaces to reduce tissue irritation.
- Industrial: Micro-fasteners (2mm thread diameter) for precision equipment, with consistent thread pitch (±0.002mm) to ensure secure assembly.
- Accept CAD/STEP/IGES files and provide 24-hour DFM analysis: For example, optimizing a 2mm-diameter part’s fillet radius (≥0.1mm) to avoid machining tool breakage, and adjusting wall thickness (≥0.3mm) to prevent deformation.
- Offer 3D-printed prototypes (3–5 days) for fit testing—critical for validating small-diameter parts’ assembly with mating components.
- Small Batches: 10–100 units for R&D or maintenance needs, with flexible scheduling to meet urgent orders.
- Bulk Production: 10,000+ units/year via automated 5-axis cells (robotic loading/unloading), maintaining consistency with 100% CMM sampling (Zeiss Contura, ±0.0005mm accuracy).
- Precision Inspection: Each batch undergoes dimensional testing (CMM), surface roughness testing (Mitutoyo SJ-210), and roundness testing (Taylor Hobson Form Talysurf).
- Compliance: Meet ISO 9001 standards, with full traceability (material certificates, machining logs, inspection reports) for audit requirements.
