欧美、日本等国已研究成功用超音速水射流切割各种非金属材料,并已达到实用水平。今后将进一步扩大应用范围。采用压力为2000～7000公斤/厘米~2的超高压水经微小喷孔(孔径为0.1～0.4毫米)喷出,喷射出的水射流速度可达到音速的3.5倍。这种超高压、超音速的水射流可以切割传统加工方 Europe, the United States, Japan and other countries have successfully studied the use of supersonic water jet cutting a variety of non-metallic materials, and has reached a practical level. In the future will further expand the scope of application. Uses ultra-high pressure water with a pressure of 2000-7000 kg / cm 2 to be sprayed through a tiny orifice (pore size 0.1-0.4 mm). The jet velocity of water jet can reach 3.5 times of the speed of sound. This ultra-high-pressure, supersonic waterjet cuts conventional processing
