Product Description

Air-Cooled Three-Way Threaded Joint CNC Milling High-Quality Stainless Steel

Product Description
Medical Device Air-Cooled Three-Way Threaded Connectors are precision-engineered components used in advanced medical equipment, particularly in laser, electrosurgical, and imaging systems where thermal management is critical. These connectors feature a three-way design that integrates cooling air or gas channels alongside primary fluid/gas pathways, with precision-machined threads for secure, leak-proof connections. Manufactured via high-precision CNC milling from biocompatible materials, they ensure efficient heat dissipation, reliable performance, and compatibility with sterile medical environments.

Product Processing
Material Selection: Medical-grade aluminum (6061-T6, 7075), stainless steel (304, 316L), or high-performance plastics (PEEK, Ultem).
Multi-Axis CNC Milling: 4-axis or 5-axis CNC milling machines used to create the complex three-way internal channels, external geometry, and threaded ports in a single setup to ensure precision alignment.
Internal Channel Machining: Precise drilling and boring of intersecting air-cooling channels and primary fluid pathways, often requiring specialized micro-tools and high-pressure coolant.
Thread Milling: Precision thread milling (rather than tapping) for high-accuracy internal and external threads (e.g., NPT, ISO metric, UNF) with smooth finishes and minimal burrs.
Deburring & Edge Radiusing: Comprehensive deburring of all internal and external edges, especially at channel intersections, using mechanical, thermal, or electrochemical methods.
Surface Finishing:

For metals: Anodizing (Aluminum), Passivation & Electropolishing (Stainless Steel).
For plastics: Smooth polishing or specific coatings.
Cleaning & Inspection: Ultrasonic cleaning to remove all machining residues. Inspection of channels with borescopes, pressure/flow testing, and dimensional verification with CMM.
Assembly & Testing (if part of a sub-assembly): Integration with O-rings, seals, or other components and final functional testing.
Product Applications
Medical Laser Systems: Connectors for cooling the laser head or fiber delivery system in surgical, aesthetic, and dental lasers.
