Introduction to laser machine

It is a laser processing machine tool mainly used to cut the plate into the workpiece with the required shape. A device that uses the heat energy of a laser beam to realize cutting.

Laser cutting is to melt and evaporate the workpiece with the energy released when the laser beam irradiates the workpiece surface, so as to achieve the purpose of cutting and engraving. It has the characteristics of high precision, fast cutting, not limited to the limitation of cutting pattern, automatic typesetting, saving materials, smooth incision and low processing cost. It will gradually improve or replace the traditional cutting process equipment.

Laser has four main characteristics: high brightness, high directivity, high monochromaticity and high coherence.

High brightness of laser: the brightness of solid-state laser can be as high as 1011w / cm2sr. Moreover, after the laser beam with high brightness is focused by the lens, it can produce a high temperature of thousands or even tens of thousands of degrees near the focus, which makes it possible to process almost all materials.

High directivity of laser: the high directivity of laser enables it to effectively transmit a long distance and ensure high power density by focusing. These two points are important conditions for laser processing.

High monochromaticity of laser: due to the high monochromaticity of laser, it ensures that the beam can be accurately focused on the focus and obtain high power density.

High coherence of laser: coherence mainly describes the phase relationship of each part of light wave. It is laser that has the singular characteristics described above, so it has been widely used in industrial processing.

Laser has been widely used in laser welding, laser cutting, laser drilling (including oblique hole, different hole, plaster hole, tipping paper hole, steel plate hole, packaging printing hole, etc.), laser quenching, laser heat treatment, laser marking, glass engraving, laser fine adjustment, excimer lithography, laser film making, laser film processing, laser packaging, laser repair circuit Laser wiring technology, laser cleaning, etc.
