WATER JET LASER CUTTING DEVICE AND CUTTING METHOD

摘要

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.
