Application advantages of desktop laser cutting machine in new product development

With the rapid development of the market economy and the rapid development of science and technology, laser cutting technology has been widely used in automobiles, machinery, electricity, hardware and electrical appliances and other fields. In recent years, laser cutting technology is developing at an unprecedented rate, with an annual growth rate of 15% to 20%. The laser cutting machine focuses the laser light emitted from the laser into a laser beam with high power density through the optical path system. The laser beam is irradiated on the surface of the workpiece, making the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam blows the molten or vaporized metal away. With the movement of the relative position of the beam and the workpiece, the material can finally form a slit, so as to achieve the purpose of cutting.

At present, there is still a big gap between the overall level of laser cutting technology in my country and advanced countries. It can be seen that laser cutting technology in the domestic market has broad development prospects and huge application space. With the development of laser cutting technology, desktop laser cutting machines based on makers, colleges and universities, K12 education and small-scale industrial production came into being. It has the advantages of high-precision, high-efficiency and high-quality non-contact cutting, which provides strong guarantee and technical support for domestic maker education and new product development.
Application advantages of desktop laser cutting machine in new product development

There are two types of laser cutting technologies: one is pulsed laser for metal materials; the other is continuous laser for non-metallic materials. The latter is an important application area for laser cutting technology. The desktop cutting machine can engrave and cut materials such as wood, leather, fabric and some metals, meeting the needs of designers for multi-material processing. The desktop laser cutting machine is one of the maker sports desktop manufacturing factories. Its lasers generally use CO2 lasers, which can engrave and cut materials such as wood, leather, fabric and some metals.

CO2 lasers have many advantages. First, it has larger power and higher energy conversion efficiency. Secondly, it utilizes the transition between the vibrational and rotational energy levels of CO2 molecules, and has relatively abundant spectral lines, and there are dozens of spectral lines in the laser output near 10 μm. In recent years, it has been found that high-pressure carbon dioxide lasers can even achieve a continuously tunable output of 9 to 10 μm. Finally, its output band is exactly the atmospheric window (that is, the atmosphere has a high transmittance for this wavelength). In addition, it has the advantages of high optical quality of the output beam, good coherence, narrow line width and stable operation.

The desktop laser cutting machine is mainly composed of high-definition camera auxiliary processing system, automatic focusing system, intelligent image extraction system, cooling system and air filtration system. Among them, the motion accuracy of the high-definition camera-assisted processing system and the focusing accuracy of the autofocus system directly affect the cutting accuracy of the desktop laser cutting machine.

At present, it is the general trend of the industry to comprehensively improve the accuracy and quality of domestic cutting equipment. Therefore, in view of the current development of laser cutting technology, the role of the current desktop laser cutting machine in the development of makers and new products is analyzed in detail, the technical shortcomings of the current desktop laser cutting machine are discussed, and targeted solutions are put forward to provide desktop Provide reference for the technological development of laser cutting machine.
