Gas cutting and protection of laser cutting machine

Air cutting is generally used in the processing of thin plates, which can ensure that there is no slag at the cutting place, high processing precision and high speed, which can meet the daily needs of customers.

Like some manufacturers and enterprises that process chassis and tool cabinets, they will use more air to cut plates. The shell production of such products generally uses 0.5-3mm thin plate processing, and often requires large-scale production and processing, so for them, using air cutting is a good choice, which can not only save gas costs, but also avoid gas replacement. time cost.

In China, most companies generally use auxiliary gas nitrogen for cutting when cutting stainless steel materials, which will increase the customer's business cost accordingly. Therefore, when cutting thin stainless steel materials, the effect of air cutting is no less than nitrogen cutting. effect, so we still recommend using air for cutting. When cutting galvanized sheet materials, because the surface of the sheet is covered with a layer of zinc, the use of oxygen may cause excessive combustion of zinc elements on the surface of the sheet, resulting in poor cutting surface. Therefore, when cutting galvanized sheet under 1.5mm, it is recommended to use air cutting . The oxygen content in air cutting is low and will not cause damage to the surface of the galvanized sheet.

The use of air cutting can significantly speed up the cutting speed of the machine and realize mass production of materials. Therefore, enterprises can equip the laser cutting machine with a special automatic loading and unloading mechanism, thereby improving the efficiency of the laser cutting machine, and at the same time, it can reduce manual intervention and reduce labor. cost and bring more economic benefits to the enterprise.

Before turning off the laser cutting machine, first drain the water in the air compressor, then turn off the air compressor, close the air output valve of the air compressor, and blow the air in the pipeline at the middle point of the laser CNC operating system.

When replacing oxygen cutting, if air cutting was used before, it is necessary to exhaust the air in the cutting head before oxygen cutting. If it is not checked frequently, the laser cutting head of the machine will be damaged for a long time, and the optical fiber will be seriously damaged. Therefore, it is necessary to do a good job of daily management and maintenance of the machine, and strictly follow the instructions of the manufacturer, so as to improve the service life of the equipment and obtain greater economic benefits.
