日本大阪大学和北见理工学院的科学家们发展出两种激光气助切割的新方法。据说,这些方法将消除传统气助切割时产生在切口底边的废物,提高不锈钢板的切口质量。在某些金属的切割过程中,引入附加的气流可以使会聚激光束的切割性能大为提高。比如,一束和氧气流同轴的激光在低碳钢上划出的切口,比只
Scientists at Japan's Osaka University and North Seetech Institute have developed two new methods of laser-assisted cutting. It is said that these methods will eliminate the traditional aids to help cut the bottom edge of the cut waste, improve the quality of stainless steel incision. In some metal cutting process, the introduction of additional airflow can make the converging laser beam cutting performance greatly improved. For example, a bundle and laser coaxial with oxygen flow cut out on mild steel, compared to only
