Embodiment Construction
[0027] Method embodiment of water jet and airflow composite assisted laser processing
[0028] The principle diagram of the embodiment of the method of water jet and airflow composite assisted laser processing is as follows figure 1 as shown,
[0029] The laser beam B is focused on the surface of the workpiece, the air beam C is coaxial with the laser beam B, and both are perpendicular to the surface of the workpiece, the diameter of the air beam C is larger than the diameter of the focus point of the laser beam B, and there is a water jet A behind the air beam C, and the water jet The beam A is also perpendicular to the surface of the workpiece and enters the kerf of the laser processed workpiece 6 .
[0030] The water of the water jet in this example is deionized water, distilled water can also be used.
[0031] In this example, the distance between the intersection point of the center line of the water jet beam and the surface of the workpiece and the center of the focal ...
