1983年,一种全新的加工方法——磨料水力喷射切割(the Abrasive Water Jet Cutting)在美国首次进入实用阶段。它以水为动力,添加细小磨料来“切割”各种材料,例如钢铁、各种合金、钛、石墨化合物、玻璃、工业陶瓷、金属基复合物、合成材料等等。 1.基本原理顾名思义,磨料水力喷射切割是利用水能和磨料来工作的。将高压水,通过喷嘴形成细的高压水射束,把硬质磨料混合到高压喷射水流中,再以高速度射向待切材料,将材料切割。切割时,增压泵把水压升到140～350MPa(约1400～3500大气压),通过喷咀喷出,喷咀用青玉制成,喷咀前有一个混合室,里边装有磨粒,磨粒通常为刚玉、金刚砂,石榴石、氧化硅等硬度很高的材料,
In 1983, a new processing method, the Abrasive Water Jet Cutting, was first put into practical use in the United States. It uses water as a driving force, adding fine abrasive to “cut” various materials such as steel, various alloys, titanium, graphite compounds, glass, industrial ceramics, metal matrix composites, synthetic materials and more. 1. Basic Principle As its name implies, abrasive water jet cutting is the use of water and abrasive to work. The high-pressure water, through the nozzle to form a fine high-pressure water jet, the hard abrasive mixed into the high-pressure jet water flow, and then fired at high speed to be cut material, the material cut. Cutting, the booster pump to the water pressure rose to 140 ~ 350MPa (about 1400 ~ 3500 atmospheres), spray through the nozzle, the nozzle is made of sapphire, the nozzle has a mixing chamber, inside with abrasive, grinding Granules are usually corundum, emery, garnet, silicon oxide and other high hardness materials,
