从七十年代末至今,苏联、澳大利亚、加拿大等国先后研究成功高压液流切断方法,用以切割金属(铝、镁、钢)和非金属(大理石、花岗石,塑料、橡胶、毛皮等)。高压液流切断方法的原理是:水或乳化液在高压泵的压力(100～220MPa)下从喷射切割器的喷嘴小孔(直径0.076～0.29mm)射出,与被加工材料接触的瞬间丧失动能,对材料产生巨大的压强。喷射切割器功率为150(kw),每分钟通过喷嘴的液体约80L。
From the late 1970s to the present, successful methods of high-pressure liquid flow cutting have been studied in the countries such as the Soviet Union, Australia and Canada to cut metal (aluminum, magnesium, steel) and nonmetal (marble, granite, plastic, rubber, fur, etc.) ). The principle of the high-pressure liquid flow cutting method is that the water or the emulsion is ejected from the nozzle orifice (diameter 0.076 to 0.29 mm) of the jet cutter under the pressure of the high-pressure pump (100 to 220 MPa), losing the kinetic energy at the instant of contact with the material to be processed , A huge pressure on the material. The jet cutter has a power of 150 (kw) and a liquid flow of about 80L per minute through the nozzle.
