Brief: Discover how CNC milling machine processing graphite plays a pivotal role in electrode manufacturing. This video highlights the precision and technology behind surgical instrument CNC manufacturing, ensuring life-saving medical devices meet global standards.
Related Product Features:
  • Biocompatible materials like 316L stainless steel, titanium, and cobalt-chrome alloys ensure safety and compatibility.
  • Achieves dimensional precision with tolerances within ±0.005 mm for critical surgical instruments.
  • High repeatability ensures consistent performance across batches, such as 5,000 hemostats.
  • Utilizes 5-axis machining centers for complex geometries like arthroscopic shavers in a single setup.
  • Swiss-type lathes are employed for precision in long, slender instruments like guide wires.
  • Secondary operations include deburring, electropolishing, and passivation per ASTM A967 for enhanced corrosion resistance.
  • Inspection and validation include CMM measurement, microhardness testing, and visual checks under 50x magnification.
  • Emerging trends like additive + subtractive hybrid machining and AI-driven quality control enhance efficiency and precision.
Faqs:
  • What tolerances are achievable in CNC machining for surgical tools?
    Typical tolerances are ±0.005 mm, but with process optimization, ±0.002 mm is possible.
  • Which surface finishes are required for surgical-grade instruments?
    An Ra ≤0.2 µm with electropolishing and passivation is standard for smooth tissue contact surfaces.
  • How does CNC machining compare with forging or casting for instruments?
    CNC machining provides tighter tolerances and repeatability, while forging is often used for initial material efficiency before CNC finishing.
