Currently on the market in the laser industry, whether it is metal or nonmetal laser marking machine laser marking machine collectively known as laser marking machine, the device can be almost all metals and non-metallic materials for processing. Is the material does not produce mechanical compression or mechanical stress fiber aurora marking machine, no "tool" wear marks, non-toxic, no environmental pollution. Simple laser marking machine operation, using computer numerical control technology enables automated processing, can be used for high-speed production line of parts and components with high efficiency machining of metal hitting laser marking machine, marking major barcodes, numbers, characters, patterns and other signs . Metal laser marking machine is generally used in fiber laser marking machine, DP semiconductor laser marking machine for processing sculpture, when general metal materials marks, caused by the ablation depth of a few microns or more lines, making the lines of color and the reflection rate is not the same as the original, resulting in the human eye visual contrast effect, people can sensitive to these lines, the lines constitute barcodes, numbers, designs, trademarks, etc. are also the same effect. Non-metallic laser marking machine mainly EP semiconductor laser marking machine, CO2 laser marking machine, the applicable range of ceramics, organic products, paper products, etc., when non-metallic materials marking: For glass materials, ablation of these the lines of "clouding" effect; for plastic materials, due to photochemical reactions and the role of ablative laser marking machine laser machine, there is a visual contrast and clouding effect. Laser marking machine at work due to the processing of different thickness of the product, so it is necessary to work with the focus adjustment function, before the old section of the laser marking machine basically did not install an infrared autofocus system, so the operation is too much trouble, and now all laser standard machine models are fitted with infrared autofocus system, laser coders its essence is a focal length can be adjusted up or down to adjust the mechanical structure. Current laser marking machine There are two ways to adjust the focal length of the cavity lifting and bench lift two kinds. Resonator lift focus adjustment, due to the weight of the cavity is determined by the design of the machine, not with the laser machining of workpieces of different changes. Also due to the small cross-sectional area of ??the cavity, suitable for Ω-type linear guides and linear bearings, greatly improving the stability of the movement, the whole body parts less laser marking machine, mechanical principle is simple. As a result of the lifting of the cavity mode, which is particularly suitable for machines with the use of the line.
