The cutting machine using the ultraviolet laser cutting system is referred to as the micro ultraviolet laser cutting machine, which has higher cutting accuracy and better cutting effect than the traditional laser cutting machine. Laser cutting machine is mainly composed of laser generator, machine tool host, external optical path, numerical control system, voltage regulator power supply, cutting head, operating table, chiller, gas cylinder, air compressor and other components, each component is indispensable to achieve the cutting task, if the parts in the process of wear also need to be replaced in time to ensure the normal operation of the equipment.
The nozzle is located at the bottom of the cutting head, which is mainly used to keep the distance tracking of the cutting head to the workpiece, adjust the direction of the high-pressure air flow and the air pressure through the internal shape of the nozzle, maintain the pressure between the workpiece and the nozzle, and prevent the slag from backsplashing into the inside of the cutting head to protect the inside of the cutting head. Although it is non-contact cutting, it is also a loss. Today’s professional UV laser cutting machine manufacturers will introduce in detail when the nozzle is best to replace.
When it is found that the follow-up is not sensitive, the cutting surface of the plate is not smooth, the nozzle hole is deformed, and the gas flow direction is problematic, and it needs to be replaced quickly; Slag on the nozzle surface causes the nozzle surface deformation, resulting in gas flow problems, need to replace or check the problem.
If the nozzle is not replaced in time, it may affect the quality of the cutting section and the cutting of the workpiece with a sharp Angle or a small Angle, resulting in local excessive melting problems, and if the thick plate is cut, there may be problems such as impenetrable cutting.
How to choose when replacing the nozzle? First of all, single-layer nozzle is generally used for melting cutting, using nitrogen or compressed air as auxiliary gas, suitable for fine cutting with high precision and surface quality requirements; The double-layer nozzle is generally cut by oxidation, and the air flow is gathered and compressed twice. The cutting effect of carbon steel is remarkable, and it is suitable for thick plate cutting.
Therefore, vulnerable and consumable accessories have a specific life cycle, the general ultraviolet laser cutting machine nozzle is better to change once every three months, and it can also be checked according to the actual use of whether it needs to be replaced.
