Laser Cutting Nozzles

Description

The ceramic ring for the nozzle of a laser cutting head is usually used at the bottom of the laser head (cutting head, welding head, cladding head, etc.). The base material of the nozzle is red copper and red copper chrome plating. The function of the nozzle is to prevent impurities such as molten stains from rebounding upward and contaminating the focusing lens through the nozzle; To control the gas diffusion area and size, the main function of the laser cutting copper nozzle ceramic ring is to transmit the electrical signals collected by the laser head nozzle; The main structure is a three part group consisting of ceramic body, stainless steel parts, and copper needles.

Product Features

• High precision calibration
• Long service life
• Better coaxiality
• High design and processing accuracy

he ceramic ring of the laser head nozzle is usually used at the bottom of the laser head (cutting head/welding head/cladding head, etc.). The base material of the nozzle is red copper and red copper chrome plating. The role of the nozzle is to prevent impurities such as molten stains from rebounding upward, passing through the nozzle, and polluting the focusing lens; Control the gas diffusion area and size to control the cutting quality.

Effect of nozzle on cutting quality: The coaxiality of the nozzle outlet hole center and the laser beam is one of the important factors affecting cutting quality. The thicker the workpiece, the greater the impact. When the nozzle is deformed or has molten stains, it will directly affect the coaxiality. Therefore, the nozzle should be carefully stored to avoid damage and deformation. The manufacturing accuracy of nozzle shape and size is high, and attention should be paid to the correct method during installation. If it is necessary to change various conditions during cutting due to the poor condition of the nozzle, it is better to replace the nozzle with a new one.

The main function of the laser ceramic ring is to transmit electrical signals collected by the laser head nozzle; The main structure is composed of three parts: ceramic body, stainless steel parts, and copper needles. It has a small coefficient of thermal expansion, high resistivity, high surface finish, and is not easy to deform after being heated. The transmission signal is stably output, and the airflow with a high finish can smoothly pass through, resulting in better cutting effect.
