喷水磨粒切割是喷水切割技术的进一步发展,已在1983年进入实用阶段,可以切割钢及其合金、钛、石墨化合物及玻璃等。喷水磨粒切割一般是在压力为207～379MPa、流速为16 L/min的水流中加入磨粒,如石榴石和氧化硅等进行切割。高压水是由增压泵供给的,喷嘴口用青玉制成。在喷嘴口下面有一个混合室,干磨粒与高压水就在这里混 Water jet abrasive cutting is a further development of water jet cutting technology. It was put into practical use in 1983 and can cut steel and its alloys, titanium, graphite compounds and glass. Water jet abrasive cutting is generally in the pressure of 207 ~ 379MPa, flow rate of 16 L / min in the flow of water added abrasive, such as garnet and silicon oxide cutting. High-pressure water is supplied by the booster pump, and the nozzle port is made of sapphire. There is a mixing chamber below the nozzle opening where dry abrasive particles mix with high pressure water
