利用液体射流的动能进行切削已有数十年的历史。这种工艺通常是使流体在70～500MPa的压力下,从直径为0.05～0.4mm的喷嘴(这类喷嘴往往采用人造蓝宝石、金刚石或刚玉等制成,其使用寿命可达200～500h)内以300～1000m/s的超音速射出。这种射流的强大作用力能使被加工材料随着其逐层微粒的分离而最后导致断裂。在该加工过程中,射流的动能被转化为进行液力切 It has been a decades-long history to use the kinetic energy of liquid jets. This process is usually to make the fluid under the pressure of 70 ~ 500MPa, from the diameter of 0.05 ~ 0.4mm nozzle (such nozzles are often made of artificial sapphire, diamond or corundum, etc., its service life of up to 200 ~ 500h) 300 ~ 1000m / s supersonic injection. The strong force of this jet can cause the material to be processed to eventually break as its layer-by-layer particles separate. During this process, the kinetic energy of the jet is converted to hydraulic cutting
