Medical-Grade CNC Machining and PVD Finishing for SUS304 Precision Stainless Components
CNC Machining of High-Precision Medical Components: Stability, Accuracy, and Biocompatibility
High-precision medical components play a critical role in surgical instrumentation, diagnostic systems, and implant-support devices. These parts require micron-level accuracy, smooth surfaces, and corrosion resistance for contact with human tissue or fluids. At Neway, we specialize in multi-axis stainless steel CNC machining and precision machining of SUS304 for medical applications, ensuring tight tolerances and compliance with ISO 13485 quality standards.
For enhanced surface performance, we apply PVD coatings that improve wear resistance, aesthetics, and chemical stability, all within a cleanroom environment.
Why SUS304 Stainless Steel Is Ideal for Medical Precision Parts
Medical-Grade Corrosion Resistance and Cleanability
SUS304 stainless steel offers excellent resistance to oxidation, cleaning chemicals, and sterilization cycles. It complies with ASTM A240 and ISO 7153-1 standards for non-implantable medical instruments and ensures safe contact with biological environments.
Excellent Machinability for Complex Features
With proper feeds, tooling, and coolant control, SUS304 enables fine-feature machining such as micro-slots, holes, and non-standard profiles. It is especially well-suited for parts requiring both internal cavity structures and precision external geometry.
Multi-Axis and Precision CNC Machining for Medical Components
Complex Geometries with Multi-Axis Control
Using 4-axis and 5-axis machining centers, we produce highly complex medical components with:
Tolerances down to ±0.005 mm
Angular surface finishing for ergonomic design
Undercuts, recesses, and deep pockets in a single setup
Multi-axis machining reduces handling errors and ensures better repeatability for parts like surgical brackets, housings, and connector sleeves.
High-Fidelity Precision Machining
For features that require extreme dimensional accuracy, such as guide rails, valve seats, or sealing interfaces, our precision machining ensures:
Flatness ≤ 0.01 mm across mating surfaces
Hole roundness and position accuracy ≤ ±0.01 mm
Surface finish Ra ≤ 0.4 µm on contact areas
PVD Coating for Enhanced Durability and Surface Aesthetics
We apply PVD coatings to protect machined components and meet visual identification or friction control needs:
TiN, TiCN, or DLC coatings with 1800–2500 HV hardness
Thickness: 1–2 µm for tight-tolerance compatibility
Colors: gold, silver-gray, black, or customized per device sets
PVD coatings are biocompatible and ISO 10993-tested for use in surgical-grade tools and reusable components.
Quality Control and Medical Compliance
CMM and optical inspection for all dimensional features
Surface roughness and coating thickness validation
PVD adhesion testing per ISO 1071-2
Quality documents: COC, RoHS, REACH, ISO 13485 traceability
