Brief: This video frames the solution within typical operational contexts for clearer understanding. You will see a detailed walkthrough of how Grade 304 and 316L Stainless Steel Biocompatible CNC Milling Parts are manufactured for critical medical applications. We demonstrate the precision machining process, showcase complex geometries like thin walls and micro-holes, and explain how tight tolerances and superior surface finishes ensure reliability in surgical instruments, diagnostic equipment, and implantable devices.
Related Product Features:
  • Manufactured from biocompatible Grade 304 or 316L stainless steel, with 316L offering enhanced corrosion resistance for implantable devices.
  • Produced using multi-axis (3/4/5-axis) precision CNC milling for complex contours, micro-milling, and deep cavity machining.
  • Holds extremely tight dimensional and geometric tolerances, typically within ±0.01mm to ±0.05mm.
  • Achieves fine surface finishes, with Ra < 0.8 µm standard and optional electropolishing for enhanced performance.
  • Suitable for a wide range of medical applications including surgical instruments, diagnostic equipment, and drug delivery systems.
  • Undergoes rigorous quality assurance with 100% dimensional inspection and material certification per ISO 13485.
  • Available with secondary operations like deburring, passivation, and ultrasonic cleaning for superior cleanliness.
  • Designed to handle complex features such as thin walls, micro-holes, fine threads, and high aspect ratios.
FAQs:
  • What are the key differences between Grade 304 and 316L stainless steel for medical parts?
    Grade 304 offers general corrosion resistance, while Grade 316L provides enhanced corrosion and pitting resistance with lower carbon content, making it the preferred choice for prolonged internal contact in implantable devices due to its superior biocompatibility.
  • What level of precision can be achieved with your CNC milling process?
    Our precision CNC milling process holds extremely tight dimensional and geometric tolerances, typically within ±0.01mm to ±0.05mm (±0.0004" to ±0.002"), and can achieve surface roughness as fine as Ra 0.4 µm to 0.8 µm for high-precision applications.
  • Are these parts compliant with medical industry quality standards?
    Yes, these parts are manufactured under a quality management system compliant with ISO 13485:2016. They undergo 100% dimensional inspection, come with material certification, and the biocompatibility of 316L is evaluated per ISO 10993-1, ensuring they meet stringent medical industry requirements.
  • What medical applications are these precision components used for?
    These components are critical for various medical applications, including surgical instruments like laparoscopic tools, diagnostic and imaging equipment probes, implantable device housings for pacemakers, dental and orthopedic devices, and precision parts for drug delivery systems such as insulin pumps.
