High-Performance Laser Cutting Nozzles from China Suppliers | Factory Direct for Enhanced Efficiency and Reduced Costs
laser cutting nozzle core function
Focusing auxiliary gas
Compressed air/oxygen/nitrogen is precisely directed through the nozzle to remove slag and cool the cutting area
Protect the optical lens
prevent metal spatter contamination of the focusing mirror, extend the service life of the lens
Control cutting quality
Nozzle aperture and airflow stability determine the smoothness and verticality of the incision
Suitable for multi-power
from 500W low-power to 20kW ultra-high-power lasers, dedicated nozzles are required
mainstream types and selection suggestions
- Standard nozzle (1.0-3.0mm aperture): suitable for conventional cutting of carbon steel and stainless steel
- Double-layer nozzle: inner gas conduction, outer barrier slag, suitable for highly reflective materials (aluminum, copper)
- Conical nozzle: enhanced gas flow rate for precision cutting of ultra-thick plates (≥25mm)
- Ceramic coated nozzle: high temperature impact resistance, suitable for continuous 8 hours or more high intensity operation
the five advantages of high-performance nozzle
- Precision machining technology: 0.01mm aperture tolerance, CNC CNC machine tool precision forming
- Long service life: hard brass/tungsten steel material, life up to the ordinary nozzle 3-5 times
- Intelligent compatible design: suitable for mainstream brands such as Trumpf, Bystronic, Mazak, etc
- Mirror-polished inner wall: reduces gas turbulence and increases cutting speed by more than 15%
- Modular quick change structure: 10 seconds to complete disassembly, reduce equipment downtime
FAQ
Q1
How to determine the nozzle needs to be replaced?
When the cutting surface is rough, the slag increases or the aperture deformation exceeds 0.1mm, it is necessary to replace it immediately, and it is recommended to check it every 40-50 hours during the operation cycle.
Q2
How to choose nozzle aperture for different power lasers?
- ≤2kW: 1.2-2.0mm is recommended
- 3-6kW: 2.5-3.0mm recommended
- ≥8kW: 3.5-4.5mm large aperture nozzle needs to be customized
Q3
Is it necessary to use a special nozzle for oxygen assisted cutting?
Yes, oxygen cutting needs to use oxidation resistant coating nozzles (such as chrome plated type) to avoid high temperature oxidation resulting in enlarged aperture.
Q4
How to clean and maintain the nozzle?
Use a special nozzle through the needle to remove internal carbon deposits, do not scratch the inner wall of hard objects, storage should be sealed and dust-proof.
Q5
Double nozzle is more expensive than single nozzle, is it worth buying?
When processing aluminum, copper and other materials, the double-layer nozzle can reduce the probability of lens pollution by more than 60%, and it is more economical to use for a long time.
Q6
What equipment parameters should be provided at the time of purchase?
Need to confirm the laser power, nozzle thread specifications (such as M10×1), gas type and cutting material thickness.
