与扫描振镜的冷消融加工方式相比,如果能正确采用固定加工头微切割加工,则能形成更陡的锥角,同时保持良好的边缘质量。优化的喷嘴能够提供加工气体,在高压下去除材料的切缝。除了激光参数,喷嘴的几何形状和位置,以及加工气体的类型和压力同样显著影响着切割效果。另一个重要的方面就是合适的工件固定夹具的发展,同时支持可靠的固定和材料的自由切割。要将设计图导入激光系统加工时,必须考虑激光的切入以及出口的位置。当涉及高 Compared with the cold ablation of the scanning galvo, a steeper taper angle can be formed if the fixed-head micro-cutting is correctly used, while maintaining good edge quality. Optimized nozzles provide process gas to remove the material under high pressure. In addition to the laser parameters, the geometry and location of the nozzle, as well as the type and pressure of process gas, also have a significant effect on the cutting result. Another important aspect is the development of suitable workholding fixtures, while supporting reliable fixing and free cutting of materials. To import a design into a laser system, you must consider the laser plunge and exit location. When it comes to high
