一种水流激光切割装置及切割方法
摘要：
本发明实施例提供一种水流激光切割装置及切割方法，涉及激光切割领域，能够切割精密工件，提高切割控制精度，而且减少切割时对精密工件造成的危害。水流激光切割装置包括冲击流体喷射单元和至少一个激光束发射单元；每个激光束发射单元用于向切割线发射激光，使切割线处的工件变为熔融态；冲击流体喷射单元用于向熔融态的切割线喷射冲击流体，利用冲击流体的冲击力分割熔融态的切割线，并且去除切割线处的溶屑，冲击流体为水与蒸汽的混合物。本发明实施例用于工件的切割。
摘要（英）：

There are provided a water jet laser cutting device and cutting method. The water jet laser cutting device includes an impulsive fluid jet unit and at least one laser beam emitting unit. Each laser beam emitting unit is configured to emit laser toward a cutting line, so as to turn a workpiece at the cutting line into a molten state. The impulsive fluid jet unit is configured to jet an impulsive fluid toward the cutting line in a molten state, so as to cut apart the cutting line in a molten state with an impulsive force of the impulsive fluid, and remove molten scraps at the cutting line.
