Brief: Explore what sets this solution apart in an easy-to-follow presentation. This video showcases the advanced manufacturing process for precision stainless steel tubes, demonstrating how high-precision laser cutting and CNC micro-milling create complex side-hole needles with exceptional dimensional control and burr-free features for demanding micro-fluidic applications.
Related Product Features:
  • Manufactured from certified 304 or 316L stainless steel tubing for superior corrosion resistance and chemical compatibility.
  • Utilizes high-precision fiber laser cutting for primary shaping, ensuring clean ends and perfect perpendicularity with minimal heat-affected zone.
  • Employs CNC micro-milling to create precise side ports, slots, or complex lateral geometries with positional accuracy of ±0.01 mm.
  • Achieves burr-free edge quality with surface finish Ra < 0.8 µm and optional electropolishing for ultra-smooth internal lumen.
  • Capable of producing needles with outer diameters from 0.5 mm to 10.0 mm and side-hole diameters as small as 0.10 mm.
  • Features comprehensive metrology including optical measurement and micro-CT scanning to verify all critical dimensions and surface finish.
  • Suitable for advanced applications in chromatography, microfluidic devices, precision medical sampling, and semiconductor manufacturing.
  • Provides full material traceability and documentation with detailed inspection reports and certification of compliance.
FAQs:
  • What are the main advantages of using CNC micro-milling for side-hole creation?
    CNC micro-milling provides extremely precise hole diameter and position, enables complex hole shapes like rectangular slots and tapered ports, delivers superior internal edge quality with minimal to zero burrs, and ensures accurate intersection between the side hole and internal lumen.
  • Which stainless steel grade should I choose for my application?
    304 stainless steel is suitable for general purpose applications, while 316L stainless steel is preferred for high corrosion and chemical resistance requirements, especially in demanding environments like medical and chemical processing.
  • What quality control measures are implemented during manufacturing?
    Each needle undergoes comprehensive metrology using optical measurement systems, video measuring machines, and potentially micro-CT scanning to verify side-hole dimensions, position, internal surface finish, and overall geometry, with full material traceability and detailed inspection reports.
  • What types of applications are these precision laser cut stainless steel tubes suitable for?
    They are ideal for advanced chromatography and mass spectrometry, microfluidic and lab-on-a-chip devices, precision medical sampling and infusion, fuel injection and sensor technology, and semiconductor manufacturing applications requiring exact lateral geometries.
