laser cutting machine

The specific operation process is as follows:

1. Comply with the safety operating procedures of general cutting machines. The laser is strictly started according to the laser startup program.

2. Operators must undergo training, be familiar with equipment structure and performance, and master relevant knowledge of operating systems.

3. Wear labor protective equipment according to regulations, and wear protective glasses that comply with regulations near the laser beam.

4. Before identifying whether a certain material can be irradiated or heated by laser, do not process it to avoid potential hazards such as smoke and steam generation.

5. When the equipment is started, the operator shall not resign or be in custody without authorization. If you need to leave, stop or cut off the power switch.

6. Place the fire extinguisher where you can reach it; Turn off the laser or shutter when not processing; Do not place paper, cloth, or other flammable materials near unprotected laser beams.

7. If any abnormalities are found during the processing, the machine should be immediately shut down, the faults should be promptly eliminated or reported to the supervisor.

8. Keep the laser, bed, and surrounding areas clean, orderly, and free of oil stains, and stack workpieces, plates, and waste materials according to regulations.

9. When using gas cylinders, it is important to avoid damaging welding wires to prevent leakage accidents. The use and transportation of gas cylinders should comply with gas cylinder monitoring regulations. Do not expose gas cylinders to sunlight or close to heat sources. When opening the bottle valve, the operator must stand on the side of the bottle nozzle.

10. High voltage safety regulations should be followed during maintenance. Every 40 hours or weekly maintenance, every hour or every 6 months maintenance should be carried out in accordance with regulations and procedures.

11. After starting, the machine tool should be manually moved at low speed in the X and Y directions to check for any abnormalities.

After entering the new sequence, it should be tested first and checked for operation.

13. Pay attention to the operation of the machine tool during work to avoid accidents caused by effective travel or collision between two cutting machines.

A laser cutting machine focuses the laser emitted from the laser into a high-power laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing it to reach the melting or boiling point, and high-pressure gas coaxial with the beam blows away the melted or vaporized metal.

As the beam of light moves relative to the workpiece, the material ultimately forms a cutting seam, thereby achieving the purpose of cutting.

Laser cutting processing uses invisible beams of light instead of traditional mechanical knives, with high accuracy, fast cutting, not limited to cutting patterns, automatic layout saving materials, smooth cuts, low processing costs, and will gradually improve or replace traditional metal cutting process equipment. The mechanical components of the laser blade have no contact with the workpiece, and will not scratch the surface of the workpiece during operation; Laser cutting speed is fast, the incision is smooth and flat, and generally does not require subsequent processing; The cutting Heat-affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm~0.3mm); The incision is free of mechanical stress and shear burrs; High machining accuracy, good repeatability, and no damage to the material surface; CNC programming, capable of processing any floor plan, capable of cutting large boards, economical and time-saving, without the need for mold opening.
