CO2 laser cutting is focusing mirror CO2 laser beam is focused on the material surface material melting at the same time with the laser beam of compressed gas to blow away the molten material, and the laser beam and materials for the relative motion along a certain trajectory, thus, form a certain shape of the kerf. Since the 1970s, with the CO2 laser and CNC technology, continuous improvement and development, has now become a state-of-the-art processing methods of sheet metal cutting industry. In the fifties and sixties as a sheet material cutting method: Plate oxyacetylene flame cutting; sheet using scissors under the bed material, forming large quantities of complex parts using stamping, one-piece vibration cut. After the 1970s, in order to improve and improve the quality of the flame-cutting incision, but also to promote the ethylene oxide precision flame cutting and plasma cutting. In order to reduce the manufacturing cycle for large stamping dies and the development of CNC nibbling and EDM technology. Various cutting cutting method has its shortcomings, the scope of industrial production.
CO2 laser cutting technology th an the other obvious advantages of the method is:
(1) cutting quality. Narrow kerf width (0.1 - 0.5mm), high precision (usually hole center distance error of 0.1 - 0.4mm outline size of the error of 0.1 - 0.5mm), the cut surface roughness good (generally Ra = 12.5 - 25μm ), kerf generally do not need to re-processing can be welded.
(2) cutting speed. Such as the use of 2KW laser power, 8mm thick steel cutting speed 1.6m/min; 2mm thick stainless steel cutting speed 3.5m/min, small heat affected zone, minimal distortion.
(3) Clean, safe, pollution-free. Greatly improved the working environment of the operating personnel. Of course, the accuracy and cut surface roughness, CO2 laser cutting can not be more than EDM; cutting thickness is difficult to reach the level of flame and plasma cutting. However, the above significant advantages enough to prove: CO2 laser cutting has been and is being replaced by part of the traditional cutting process method, especially the cutting of a variety of non-metallic materials. It is the rapid development of increasingly widespread application of advanced processing methods.
Since the 1990s, due to the development of China\\ s socialist market economy, competition among enterprises is fierce, each firm must be in accordance with their terms, the correct choice of advanced manufacturing technology to improve product quality and production efficiency. CO2 laser cutting machine technology in China\\ s rapid development.
