Pay attention to the problems in the use of laser marking machines. Laser marking machines should adjust the marking methods and methods according to their characteristics and nature requirements to improve the marking quality and effect. Provide better service to customers. The basic characteristics of laser marking processing technology are as follows: 1. Non-contact processing, no tool wear, no need to change tools in the middle; 2. The laser beam is easy to guide and focus to achieve direction change, and it is easy to cooperate with the CNC system to process complex workpieces; 3. Machinable high Hardness, high brittleness, high melting point, soft material; 4. High energy density of the laser beam, fast processing speed, small deformation of the workpiece, small heat-affected zone, and small follow-up processing; 5. It is easy to combine with traditional production technology to form a production line . Looking directly at the laser is harmful to our eyes. When marking with laser, what should we pay attention to in order to ensure our safety? 1. Avoid looking directly at the laser with your eyes; 2. Use the laser in the controllable area and add warning signs; 3. Do not use without permission, and only be operated by professionally trained personnel; 4. Close the periphery of the optical path as much as possible to prevent Laser leakage; 5. Wear appropriate laser goggles; 6. The body should avoid entering the beam and its reflection range; 7. Remove unnecessary reflective objects next to the working object; 8. The z next to the processing object should be properly shielded; 9. Try as much as possible Avoid erecting the laser body at the height of the human eye; 10. Pay attention to the ventilation or exhaust of the laser processing environment; 11. The price of the laser marking machine will affect the quality of the product in many cases. In laser marking, paying attention to the above requirements and applications can provide better services. It can solve the problems in the laser marking process.
