Laser is a kind of light. Like natural electroluminescence, it is produced by the transition of atoms (molecules or ion kites) and is caused by spontaneous radiation. Although laser light is light, it is obviously different from ordinary light. The laser only relies on spontaneous emission for a very short period of time, and the subsequent process is completely determined by stimulated emission. Therefore, the laser has a very pure color, almost no divergent directionality, and extremely high luminous intensity. The laser has high coherence, high intensity, and high directivity at the same time.The metal cutting laser cutting machine processes the sheet metal parts by using a laser to be generated by a laser and then transmitted by a reflecting mirror and irradiated on the processed sheet metal parts through a focusing mirror. The processing sheet metal part (surface) is subjected to strong thermal energy and the temperature increases sharply, so that the point is quickly melted or vaporized due to the high temperature, and the operation track of the laser head is matched to achieve the purpose of processing.
(1) Comply with the safe operation regulations of metal cutting laser cutting machine. Start the laser strictly in accordance with the laser startup procedure.
(2) The operator must be trained to be familiar with the structure and performance of the equipment, and master the knowledge of the operating system.
(3) The operator should wear labor protection equipment as required, and must wear protective glasses that meet the requirements near the laser beam.
(4)Do not use a metal cutting laser cut copper sheet machine to process a certain material before it is clear whether it can be irradiated or heated with a laser, so as to avoid the potential hazards of smoke and steam.
(5) When the equipment is started, the operator shall not leave the post without authorization or be entrusted to take care of it. If you really need to leave, stop or cut off the power switch.
(6) Keep the fire extinguisher within easy reach. Turn off the laser or shutter when not processing. Do not place paper, cloth or other flammable materials near the unprotected laser beam.
When an abnormality is found in the process of processing sheet metal parts, the machine should be shut down immediately, and the fault should be eliminated or reported to the supervisor in time.
(7)Keep the laser, the bed and the surrounding area clean, orderly, and free of oil pollution. Workpieces, plates, and waste materials are stacked according to regulations.
(8) When using gas cylinders, avoid crushing the welding wires to avoid leakage accidents. The use and transportation of gas cylinders should comply with gas cylinder supervision regulations. Do not expose gas cylinders to the sun or close to heat sources. When opening the bottle valve, the operator must stand on the side of the bottle mouth.
(9) Observe the high-voltage safety regulations when repairing the metal cutting laser cutting machine. When every 40 hours of operation or weekly maintenance, and every 1,000 hours of operation or every six months, the maintenance should be carried out in accordance with regulations and procedures.
(10) After starting the machine, the machine should be manually started in the X and Y directions at low speed, and check to confirm whether there is any abnormality.
(11) After inputting the new part program, test run it first and check its operation.
(12) When working, pay attention to the operation of the machine tool to avoid accidents caused by the cutting machine going out of the effective stroke range or collision between two machines.
A metal cutting laser cutting machine costs tens of thousands or even hundreds of thousands, so you must pay attention to it during operation. Moreover, it is usually necessary to pay attention to maintenance to increase the service life of the equipment, save costs, and create greater benefits.
