D28mm Fiber Laser Bevel Cutting Nozzle
Size:D28-H20-M11/D28-H22.5-M11
Model:PB-H20-S/D,PB-H22.5-S/D
1. Core Material: Premium T2 Red Copper
- High Thermal Conductivity & Burn Resistance: Made of high-purity T2 red copper with excellent thermal conductivity. It dissipates heat rapidly during high-power thick-plate or bevel cutting to avoid burn erosion at the nozzle tip.
- Anti-splash Adhesion: Micro-level polishing on both outer surface and inner bore prevents slag and metal sparks from sticking, greatly extending the service life of each nozzle.
- Ultra-high Concentricity (≤0.01 mm): Precision CNC one-piece machining ensures the laser beam and assist gas eject coaxially, delivering vertical, smooth and burr-free cutting edges.
2. Structural Features & Design Advantages
- D28 Wide Flange for Stable Gas Flow: Knurled outer flange for easy hand-tight installation and removal. The large base forms a tight seal with the laser head gas path to eliminate gas leakage under high-speed airflow.
- Dual Height Options: H20 / H22.5. Customized for the optical path and focal length of Bodor bevel cutting heads to avoid workpiece collision during tilted cutting.
- Scientific Single / Double Layer Design:
- Single Layer (PB-H20-S / PB-H22.5-S): For Nitrogen (N₂) / Air. Ideal for high-speed fusion cutting of stainless steel, aluminum alloy and copper plates.
- Double Layer (PB-H20-D / PB-H22.5-D): Built-in flow guide ring. For Oxygen (O₂). Optimized for efficient oxidation cutting of carbon steel and low-alloy steel.
3. Installation & Operation Guide
- Coaxial Calibration: After replacing a new nozzle, use transparent tape for spot testing to verify concentricity and center the laser spot.
- Height Selection: Choose H20 or H22.5 according to your laser head focal length and cutting recipe, to prevent head collision or unstable gas flow caused by mismatched height.
