Laser cutting machine is realized by applying high power density energy generated by laser focusing. Under the control of the computer, the laser discharges through pulses to output controlled repetitive high-frequency pulse laser to form a beam with a specific frequency and a specific pulse width. The pulsed laser beam is guided and reflected by the optical path, and is focused by the focusing lens group. A small light spot with high energy density is formed on the surface of the object to be processed. The focus is near the surface to be treated, and the treated material melts or vaporizes at an instant high temperature. Each high-energy laser pulse will immediately sputter a small hole on the surface of the object.
When the laser cutting machine is working, it is very dangerous if it breaks down. Novice must be trained by professionals to operate independently. The experts of the laser cutting machine summarized 13 details of the safe work of the laser cutting machine based on their experience, and hope to help you, as follows:
1. Comply with the general safety operation procedures of the cutting machine. Start the laser strictly according to the laser startup procedure.
2. The operator must be trained, familiar with the structure and performance of the equipment, and master the relevant knowledge of the operating system.
3. Please wear labor protection articles as required, and wear protective glasses that meet the requirements near the laser beam.
4. Do not conduct any treatment before confirming whether the materials can be irradiated or heated by laser, so as to avoid the potential danger of smoke and steam
Precautions for safe operation of laser cutting machine
5. When the equipment is started, the operator shall not leave the post or be cared for without authorization. If it is necessary to leave, the operator should stop the machine or cut off the power switch.
6. The fire extinguisher shall be placed in an easily accessible place, and the laser or shutter shall be closed when not being treated, and no paper, cloth or other flammable materials shall be placed near the unprotected laser beam.
7. In case of any abnormality found in the process of handling, the machine shall be shut down immediately, and the fault shall be eliminated or reported to the supervisor in time.
8. Keep the laser, bed and surrounding area clean, orderly and free of oil stain. The workpieces, plates and waste materials shall be stacked as required.
9. When using gas cylinders, avoid flattening welding wires to avoid leakage accidents. The use and transportation of gas cylinders shall comply with the regulations governing gas cylinders. It is prohibited to explode cylinders in the sun or near heat sources. When opening the bottle valve, the operator must stand at the side of the bottle mouth.
10. Please observe the high-voltage safety regulations during maintenance. Maintenance shall be carried out every 40 hours of operation or once a week, and every 1000 hours of operation or every six months according to regulations and procedures.
11. After the machine is started, the machine shall be manually started at low speed in the x and Y directions and checked for abnormalities.
12. After entering the new part program, try running it and checking its operation first.
13. During operation, please pay attention to the operation of the machine tool to avoid accidents caused by the cutting machine exceeding the effective travel range or collision between two machines.
