What Type of Laser Cutter Nozzle is Used in Laser Cutting Machine?

The right laser cutter nozzle is a key factor in achieving high-quality and efficient laser cutting, which directly affects the cutting effect, production cost and material utilization. Therefore, in the laser cutting process, the nozzle type and design must be carefully selected according to the specific cutting requirements and material properties.

1.Types of Laser Cutting Nozzles

Choosing the right laser cutter nozzle type can significantly improve cutting quality and efficiency. The specific choice should be determined based on material type, cutting thickness and cutting requirements.
The design and type of laser cutter nozzle have an important impact on the cutting effect. The following are common types of laser cutting nozzles:

1.1 Straight nozzle

The nozzle diameter is uniform and the airflow is ejected directly. Suitable for general cutting, providing uniform airflow, suitable for a variety of materials.

1.2 Conical nozzle

The nozzle is conical in design and the airflow is concentrated. Suitable for high-power laser cutting, can provide stronger airflow, suitable for thick material cutting.

3.3 Multi-hole nozzle

There are multiple small holes on the nozzle, and the airflow is dispersed. Suitable for cutting that requires uniform airflow, reducing the heat-affected zone, and suitable for thin materials.

3.4  Adjustable nozzle

The nozzle diameter is adjustable to meet different cutting needs. High flexibility, suitable for applications with a variety of materials and cutting thicknesses.

3.5 Cooling nozzle

Built-in cooling system to prevent nozzle overheating. Suitable for high-power cutting, extend the service life of the nozzle, and maintain cutting quality.

2.Considerations for Selecting Laser Cutter Nozzles for Cutting Machines

Choosing the right laser nozzle is critical to the quality and efficiency of laser cutting. Here are some key considerations:

2.1 Material type

Carbon steel: Oxygen nozzles are usually used to promote combustion during cutting.
Stainless steel and aluminum: Nitrogen nozzles are recommended to prevent oxidation and ensure smooth cutting edges.

2.2 Cutting thickness

Thin materials: A smaller diameter nozzle can be selected to improve cutting accuracy.
Thick materials: A larger diameter nozzle is required to provide stronger airflow and cutting capabilities.

2.3 Gas type

Oxygen: Suitable for materials that need to be cut quickly.
Nitrogen: Suitable for materials that require high-quality cutting, especially stainless steel.
Air: Suitable for cost-sensitive applications and suitable for some non-metallic materials.

2.4 Nozzle design

Straight nozzle: Suitable for general cutting, providing uniform airflow.
Conical nozzle: Suitable for high-power laser cutting, capable of providing stronger airflow and better cutting results.

2.5 Cutting speed

Choose a nozzle based on the required cutting speed. A larger nozzle can increase the cutting speed, but may affect the cutting quality.

2.6 Cutting quality requirements

If you have high requirements for the smoothness and accuracy of the cutting edge, it is crucial to choose the right nozzle diameter and gas type.
