Custom CNC machining of medical device parts requires adherence to very strict standards, particularly in material selection, precision, and surface treatment. Key factors include:

1. Material Selection:
   • Stainless Steel: Commonly used types include 316L and 304 stainless steel, known for their excellent corrosion resistance and biocompatibility, making them suitable for long-term contact with human tissue and fluids.
   • Titanium Alloys: Widely used in medical implants due to their lightweight, high strength, and good biocompatibility.
2. Machining Precision:
   • Medical device parts often require high-precision machining with tightly controlled tolerances to ensure dimensional consistency and assembly accuracy.
   • During machining, it is important to avoid burrs or rough surfaces to prevent harm to patients.
3. Surface Treatment:
   • Polishing: Medical device parts typically require precision polishing to achieve a high level of surface finish, reducing friction and making cleaning easier.
   • Electropolishing: Further improves the surface finish and corrosion resistance of stainless steel.
4. Cleaning and Sterilization Requirements:
   • After production, parts must undergo strict cleaning and sterilization to meet medical hygiene standards.
