Advertising industry has always been the best stage for laser technology to show its unique characteristics. Here, laser technology can show different needs in many ways, such as light and shadow, vocal music, action, etc. the magical effect shows the characteristics of laser technology incisively and vividly. Logo, the application of logo is an important field in which laser processing technology has been widely used. The promotion and application of laser engraving and cutting machine has injected new vitality into the advertising industry and pushed the development of logo and logo to another peak of application.
1、 Working principle of laser engraving machine
The laser has high consistency, directivity and high strength. Generally speaking, one method is to generate a high-energy beam excited by a specific dielectric material and control it at a certain point on its surface, that is, at a high temperature, the material will melt or evaporate rapidly, so that we can get the required material form, that is, to change the shape of the object by controlling the energy, speed, direction and walking path of the excitation. Laser processing can meet our requirements.
Laser carving and laser cutting are two different ways of working. Generally, CO2 laser, special laser engraving software, automatic control system, precision machinery and other laser engraving processes are used. They are low-cost high-tech laser products. Laser, automatic control system and precision mechanical components are the key of measuring instruments. In the process of laser cutting, a high-energy laser beam is generated by focusing to melt or evaporate the workpiece, and then the auxiliary gas is used to blow it out to form a notch. Laser cutting is one of the most mature and widely used laser processing technologies.
2、 Characteristics and advantages of laser engraving machine
Compared with machining, laser processing has the following advantages: the advantages of laser processing are wide processing objects, small deformation, high precision, energy saving, less public hazards, non-contact long-distance processing, automatic processing and other significant advantages. The tailor is narrow, the carving is fine, and the blind groove can be cut at will; It can be easily applied to ultra-thin, fragile, brittle, soft, hard and synthetic materials, with fast cutting speed and no tool wear; Easy for numerical control and computer control: easy for assembly line operation. The development of optical, electromechanical, material, computer, control and other technologies has gradually become a new processing technology. This laser engraving machine integrates laser engraving and laser cutting, and puts forward higher requirements for laser and control system. It integrates engraving and cutting, has multiple uses, and has high cost performance. At present, it has been widely used in advertising process, mold, printing plate making, leather goods, electronic instruments and other industries.
