尽管带有冷却剂的流动工作材料在常规金属切割中通用，工业激光用户对他们的加工过程中通水仍然有点怀疑．但是，潜在的回报显然已足够高了，美国在１９９８年９月份举行的国际制造技术展览会（ＩＭＴＳ）上展示了水辅助技术的两种措施及其加工装置．第一个显而易见的例子，是
Although flow-working materials with coolant are common in conventional metal cutting, industrial laser users are still skeptical of the flow of water through their processes. However, the potential returns are obviously high enough. The United States demonstrated at the International Manufacturing Technology Exhibition (IMTS) in September 1998 two measures of water-assist technology and its processing equipment. The first obvious example is
