With the rapid development of market economy and the rapid development of science and technology, laser cutting technology has been widely used in automotive, mechanical, electrical, hardware, and electrical fields. In recent years, laser cutting technology is developing at an unprecedented speed, with an annual growth rate of 15% to 20%. The laser cutting machine focuses the laser light emitted from the laser into a high power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach a melting or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the light beam moves relative to the workpiece, the material can eventually form a cutting seam, thereby achieving the purpose of cutting.
Currently, there is still a significant gap between the overall level of laser cutting technology in China 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, universities, K12 education, and small-scale industrial production have emerged. It has the advantages of high-precision, cost-effective, and high-quality non-contact cutting, providing a 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 techniques: first, pulsed laser is suitable for metal materials; Second, continuous laser is suitable for non-metallic materials. The latter is an important application field of laser cutting technology. The desktop cutting machine can carve and cut wood, leather, fabric, and some metal materials, meeting the needs of designers for multi material processing. As one of the Makers’ sports desktop manufacturing factories, desktop laser cutting machines generally use CO2 lasers, which can carve and cut wood, leather, fabrics, and some metals.
CO2 lasers have many advantages. Firstly, it has larger power and higher energy conversion efficiency. Secondly, it utilizes the transition between vibrational and rotational energy levels of CO2 molecules, and has relatively rich spectral lines μ There are dozens of spectral lines of laser output near m. In recent years, it has been found that high pressure carbon dioxide lasers can even achieve 9-10 μ M continuously tunable output. Finally, its output wavelength is precisely the atmospheric window (i.e., the atmospheric transmittance to this wavelength is high). In addition, it also has the advantages of high optical quality, good coherence, narrow line width, and stable operation of the output beam.
Desktop laser cutting machine is mainly composed of high-definition camera assisted processing system, automatic focusing system, intelligent image extraction system, cooling system, and air filtration system. The motion accuracy of the high-definition camera assisted machining system and the focusing accuracy of the automatic focusing 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, this paper analyzes in detail the role of desktop laser cutting machines in the development of makers and new products, discusses the technical shortcomings of current desktop laser cutting machines, and proposes targeted solutions to provide reference for the technical development of desktop laser cutting machines.
