Newton Internal‑Bore Laser Cladding Heads
General Technical Features
 |
 |
- Structural Forms: Available in integrated and split configurations. Gas, powder and cooling water pipelines are internally integrated to improve accessibility for deep‑bore machining.
- Cooling System: Adopts dual‑water‑channel internal‑wall full water‑cooling design for both lenses and nozzles. Effectively prevents nozzle powder sticking and clogging, and extends service life of optical lenses and nozzles.
- Anti‑Back‑Reflection Design: Built‑in water‑cooled aperture stop suppresses back‑reflected laser light during processing, protecting optical fiber and laser source.
- Powder Feeding Performance: Mainly adopts coaxial annular powder feeding; partial models support multi‑beam powder feeding. Annular nozzle delivers ＞92 % powder utilization rate.
- Depth Adaptability: Split‑type heads support unlimited machining depth; extension mechanisms can be added for custom depth requirements. Integrated‑type heads have standard unilateral machining length, and extended versions are available upon request.
- Interface Compatibility: Supports QD / QBH / LOE fiber interfaces, compatible with mainstream fiber lasers.
- Special Configuration: FWC9000Q features triple‑beam forward‑tilted nozzle, eliminating blind zones at root of blind holes and stepped holes.
