Waterjet laser cutting is a hybrid processing method, also known as laser microjet. It combines the laser pointer with “fine” water jets, and the water jets (water jets) are accurately guided by a method similar to conventional optical fibers. The laser beam thus realizes the cutting, and the water jet continuously cools the cutting area and effectively removes the debris generated during cutting.
This technology was first applied to semiconductor wafer cutting. As the technology matures, it is gradually extended to medical equipment, watch processing, gas and jet engine turbine blades, semiconductor equipment machining, and material cutting in the manufacturing process of superhard tools. .
After the laser is focused, it will form a laser beam. When passing through the pressurized water cavity, it will push the water forward and focus into the nozzle. Finally, the laser beam will be emitted from the nozzle together with the water stream. There is no abrasive in this water stream, so the cutting is mainly based on laser. The function of water is to use the water column to guide the laser to not disperse, gather the laser energy to cut faster, and also has the effect of cooling and removing debris.
From the nozzle to the cutting workpiece, the laser beam will not be scattered, but will continue to reflect in the water column. It is similar to optical fiber transmission in principle. The laser beam can be guided at a distance of up to 10cm to achieve a neat Cut seams without refocusing or distance control.
Waterjet laser cutting can obtain very high cutting quality, no thermal damage to the material, no burning or thermal degradation, fewer burrs, smoother surface, and straight edge cutting with higher precision, which helps to maintain the high precision of the aperture, etc. Advantages, and the water jet can continuously cool the cutting area, and can effectively remove the debris generated during cutting.
For processors, waterjet green laser pointer cutting can have a faster production speed, a wider range of processing materials, higher reliability and higher cutting quality, and lower cutting costs. With the emergence of more new materials, all these characteristics of waterjet laser cutting will also be more widely used.
