Laser cutting of metal based on the processes of heating, melting, evaporation, chemical reactions of burning and removal of melt is one of the most promising processes for preparing parts and components on an industrial scale. Focused laser radiation provides a high concentration of energy, which allows virtually any metal or alloy to be separated, regardless of their thermal properties. Thus it is possible to obtain narrow cuts with a minimum heat-affected zone.
Laser cutting prevents mechanical impact on the material, resulting in a product that is free from all types of deformation, whether acquired during the cutting process or after cooling. Consequently, laser cutting can be performed with high accuracy, permitting to work with easily deformable and non-rigid components and parts.
High power density of laser radiation makes it possible to achieve production efficiency and high quality of the cut surfaces. Easy and relatively simple laser control system enables the creation complex plane contours and three-dimensional parts, using a high degree of process automation. These features of laser cutting clearly demonstrate the advantages of the technology over traditional methods of metal processing.
