Sharing of basic knowledge of laser cutting machine maintenance

　　 Fiber laser cutting machine is widely used in industry, both in terms of cutting speed and flexibility, we will introduce how to maintain the cutting head of fiber laser cutting machine.

　　 Fiber laser cutting machine has high laser cutting flexibility, fast cutting speed, high production efficiency, and short product production cycle , Whether it’s simple or complex parts, you can use laser for rapid prototyping and cutting. Laser cutting is the use of laser to cut wood, plastic, metal, rubber and other materials. This technology has become an important part of the manufacturing process, but laser The cutting head of the cutting machine will wear out for a long time, so how do we maintain the cutting head?

　　 Electrodes and nozzles are important consumables in the daily operation of CNC plasma cutting machines, especially imported electrodes and nozzles Therefore, effectively extending the life of electrodes and nozzles will greatly reduce the production cost of plasma cutting. The consumption of electrodes and nozzles is related to air pressure, cooling water pressure, voltage, current, air supply quality, quality of consumables and other factors. Pay attention to some abnormal consumption and machine failures caused by laser cutting. I have encountered the phenomenon that the entire set of electrodes and nozzles are often burned out when the cutting machine starts arcing. Some burned out within 0.5~1h after cutting.

　　 After inspection, it was found that the arc generated between the electrode and the nozzle sintered the edge of the electrode and the nozzle together. For this reason, we adopted different types of electrodes and nozzles, replaced new cutting guns, and adjusted the air pressure. Although the effect of measures such as water pressure and water pressure has changed, it is not significant. Sometimes it will recover. It is inexplicably normal. After repeated inspections, it is found that the failure is caused by accidental air loss during the cutting process. Sectional investigation found that the electric valve The solenoid valve in the console is de-energized, the solenoid valve is de-energized, and the control cable is in poor contact. Due to the short time of the cut-off time, it just needs to be measured and it is not easy to check errors. It is in this short period of time that the electrodes and nozzles are burned out and repaired. After the wire is fixed, the fault is eliminated.

　　Laser cutting equipment is easy to operate, saves time and effort, and performs fully automated production cutting. You only need to import the graphics to be cut into the special cutting machine software before processing. The software will match the size of the material and design by itself. Reasonable cutting path, in order to reduce material waste, without manual positioning of materials, one person operates multiple devices, reducing labor and production costs.

　　 The above is how to maintain the cutting head of the fiber laser cutting machine from our Hebei company. If you have any needs, I hope you can contact us in time. We welcome your visit.
