Description
Precision CNC Machining for Critical Interfaces
5-axis CNC turning and grinding achieve Ra 0.1μm mirror finish on the taper junction, minimizing wear and corrosion.
Tight tolerances (±5um) ensure perfect compatibility with femoral heads and surgical instruments.
Post-process CNC polishing eliminates micro-defects, reducing fretting corrosion risk.
Post-Processing for Enhanced Performance
Stress-relief heat treatment prevents distortion and improves fatigue life (tested to 10 million cycles). Ele-polishing further refines surfaces to Ra <0.05μm, reducing bacterial adhesion risks.
Clinical Benefits
Enhanced Longevity – Porous structures promote stable long-term fixation, reducing revision surgeries.
Reduced Stress Shielding – Gradual stiffness transition prevents bone resorption.
Improved Surgical Outcomes – CNC precision ensures perfect taper lock, minimizing micro-motion.
Faster Recovery – Optimized surface textures accelerate tissue attachment.
Advantage
Weight Reduction Without Sacrificing Strength
Additive manufacturing allows hollow structures and material-gradient designs, with CNC finishing guaranteeing fatigue-resistant surfaces. Example: Ti6Al4V aircraft components achieving 30–50% weight savings while meeting MIL-STD-2042 load requirements.
