Hongshan double-layer nozzle

The Hongshan double-layer nozzle is the core accessory of fiber laser cutting machines, designed specifically for efficient and detailed cutting scenarios. Its detailed introduction is as follows:

Material and Craftsmanship

Main material: Made of high-purity copper, it has excellent thermal conductivity and high temperature resistance (based on actual reports). It can dissipate heat at a suitable speed in the high-temperature environment of laser cutting, avoiding deformation caused by overheating and affecting cutting accuracy. Some models have undergone chrome plating treatment on the surface (such as black and silver plated versions) to enhance performance and corrosiveness, while improving surface smoothness and reducing the adhesion of slag during cutting.

Processing technology: The dimensional accuracy of the inner hole and spray hole is confirmed through CNC machining with appropriate precision (tolerance controlled within ± 0.01mm). The double-layer structure of the airflow channel is optimized to ensure uniform and stable gas flow rate, improve cutting efficiency and cutting quality.

structural design

Double layer airflow channel: The interior adopts a double-layer coaxial design, with the outer layer channel conveying auxiliary gases (such as nitrogen and oxygen) and the inner layer channel guiding the laser beam. This structure can form a stable laminar flow of gas, effectively blowing away cutting slag, reducing cutting burrs, and protecting the laser focusing lens from contamination.

Cone shaped nozzle head: The nozzle head is conical in shape, with a wide range of aperture specifications at the front end (including 1.0mm, 1.2mm, 1.4mm, 1.6mm, 2.0mm, etc.), which can be flexibly selected according to the thickness of the cutting material and the laser power, to confirm that the laser energy is concentrated on the cutting point and achieve excellent cutting.

Threaded connection: Adopting standard M14 external thread design, it is well adapted to the cutting head of Hongshan laser cutting machine, easy to install and disassemble, and has excellent sealing performance to avoid gas leakage affecting the cutting effect.

performance advantage

Good cutting efficiency: The double-layer airflow design optimizes gas utilization and increases cutting speed by more than 20% compared to ordinary single-layer nozzles, especially when cutting medium thick plates (6-20mm carbon steel).

Excellent incision quality: Stable laminar gas can effectively prevent cutting splashes, with a smooth and polished incision, good verticality, and reduced subsequent polishing processes. It is suitable for industrial scenarios with high precision requirements (such as automotive parts and fine mechanical processing).

Strong practicality: The combination of purple copper material and chrome plating technology extends its service life by more than 30% compared to ordinary nozzles, reducing the frequency of accessory replacement and usage costs.

Wide adaptability: compatible with Hongshan's full range of fiber laser cutting machines, and can also adapt to some well-known models such as Wanshunxing and Dazu, meeting the equipment compatibility needs of different users.

Specifications and Applications

Caliber specifications: The mainstream calibers include 1.0mm, 1.2mm, 1.4mm, 1.6mm, 2.0mm, etc. Among them, 1.2mm and 1.6mm are universal specifications, respectively suitable for excellent cutting of thin plates and effective cutting of medium thick plates.

Application scenarios: Widely used in industries such as steel structure manufacturing, automotive parts production, aerospace metal processing, etc., especially in automated production lines that require high cutting accuracy and efficiency.

Precautions

Regularly clean the slag and dust on the surface of the nozzle, and confirm that the airflow channel is smooth;

Select the nozzle with the corresponding diameter based on the cutting material and thickness to avoid a decrease in cutting quality due to mismatched diameters;

Confirm that the threaded connection is tight during installation to prevent gas leakage from affecting the cutting effect.
