Laser cutting nozzle

Laser cutting nozzle is a core consumable component of laser cutting equipment, used to guide the laser beam and assist gas cutting. Its detailed characteristics are as follows:

Material and Structure

Main material: Made of high-purity oxygen free copper, it has excellent thermal and electrical conductivity, and can dissipate heat at a suitable speed to avoid deformation or damage to the cutting nozzle due to high temperature; Some excellent models have nickel or chrome plated surfaces to enhance corrosion resistance and performance.

Structural design:

Nozzle shape: divided into various shapes such as straight tube, cone, and oblique cut, different shapes are suitable for different cutting scenarios (such as straight tube suitable for thick plate cutting, oblique cut suitable for thin plate cutting).

Aperture specification: The common aperture range is 0.8-4.0mm, and the corresponding aperture should be selected according to the laser power and cutting material thickness to confirm the detailed coupling between the laser beam and the auxiliary gas.

Installation interface: Adopting standardized thread or buckle design, suitable for cutting heads of mainstream laser cutting machines (such as fiber laser cutting heads, CO ₂ laser cutting heads).

performance advantage

Good cutting accuracy: The finely processed aperture and nozzle shape can focus the laser beam finely, assist in even gas injection, and improve the smoothness and perpendicularity of the cutting edge, reducing defects such as slag and burrs.

Heat dissipation and practicality: Oxygen free copper material is suitable for heat dissipation and extends the service life of the cutting nozzle; Adapt to different power lasers (500W-20000W) to maintain stable performance in continuous cutting operations.

Wide adaptability: compatible with cutting various metal materials such as carbon steel, stainless steel, aluminum alloy, brass, etc. The diverse selection of aperture and shape can meet the cutting needs of thin, medium thick, and thick plates.

Application scenarios

The laser cutting production line widely used in industries such as metal processing, sheet metal manufacturing, automotive parts, and kitchenware production is a key consumable component of fiber laser cutting machines and CO ₂ laser cutting machines. It is necessary to select the corresponding type of cutting nozzle according to the cutting material, thickness, and laser power, and regularly replace it to protect the cutting quality.
