Product Description

Stainless Steel Capillary Laser Cutting with Custom Precision Solutions

Product Description
Stainless Steel Capillary Tube Precision Laser Cutting (OD 0.5mm–25mm) with Slotting and Perforation is a specialized micromachining service turning fine tubing into functional components with complex geometries. Using advanced CNC pulsed fiber lasers with rotary axes, it creates precise slots, holes, and intricate patterns in capillaries from 0.5mm to 25mm OD. The non-contact process ensures clean, burr-free cuts with minimal HAZ, preserving mechanical properties and corrosion resistance. Suitable for stainless steel grades like 304, 316L, and 17-4PH, these capillaries are crucial in medical devices, analytical instruments, fluid systems, and precision industries where accuracy and integrity are essential.

Product Processing
Material Selection & Preparation: Choose appropriate stainless steel grade (304, 316L, 17-4PH) based on requirements. Verify tubing dimensions (OD, ID, wall thickness), clean, and prep for processing.
CAD/CAM Programming: Designs are converted into precise laser paths using specialized software. Optimize nesting and paths for material use and minimal thermal input.
Precision Fixturing: Securely mount the tube in a CNC rotary chuck for precise axial and rotational positioning, crucial for accuracy on small tubes.
Laser Micromachining (Core Process): A high-precision pulsed fiber laser performs all cuts:

Laser Slotting: Cut longitudinal, helical, radial, or custom slots with precise width and length control.
