Why do Lasers engrave?

Laser engraving is based on numerical control technology and laser is the processing medium. Under the irradiation of laser, the processing material will melt and vaporize instantly, which will lead to the physical denaturation, so as to achieve the purpose of processing. Laser processing features: no contact with the material surface, not affected by mechanical movement, the surface will not deform, generally without fixing. It is not affected by the elasticity and flexibility of the material, so it is convenient to use the soft material. High precision, high speed and wide application. Laser carving is divided into laser cutting, laser carving, laser marking, glass (crystal) carving and other common ways. Laser carving process is realized by laser carving machine, laser marking machine, laser cutting machine and other equipment. Laser carving is widely used in advertising processing, gift processing, packaging engraving, leather processing, cloth proofing, seal carving, product marking, etc Seal carving and many other industries. Common materials for laser carving: 1. Processing of non-metallic materials (CO2 laser): plexiglass, wood, leather, cloth, plastic, rubber plate for printing, double color board, glass, synthetic crystal, horn, paperboard, density board, marble, jade, etc

(1) Observe the light output in the laser tube, if there is laser in the laser tube.

A: Check the laser intensity at the light outlet of the laser tube, and clean the light outlet of the laser tube.

B: If it is found that the laser color in the laser tube is obviously abnormal, it can be basically judged that the laser tube is leaking or aging, and the laser tube should be replaced.

C: If the laser color in the laser tube is normal and the intensity of the light outlet is normal, adjust the light path for testing.

(2) If there is no light in the laser tube.

A: Check whether the circulating water is unobstructed

B: If the circulating water is unobstructed, short circuit the water protection for testing.

C: Check whether the laser power supply is normal.

D: Check whether the wiring related to the laser power supply is reliable, and check whether there is any abnormality along the cable.

E: Replace the laser power supply or control board for testing.
