部技术局和第二技术交流站于一九八○年十月下旬在北京通县召开了激光打孔技术交流会暨GJK-1激光打孔机及工艺鉴定会。会上,六二五所、西工大、四一○厂、一○○厂、四三○厂等单位作了经验介绍,并对六二五所研制的GJK-1激光打孔机及工艺进行了鉴定。激光打孔是一种新的工艺方法,尤其是对各种软硬材料加工φ1毫米以下精密小孔、小缝效果良好,解决了航空发动机气冷叶片、喷嘴的精密小孔加工等不少生产实际问题。会议建 Ministry of Technology and the second technical exchange station in late October 1980 held in Beijing Tongxian laser drilling technology exchange and GJK-1 laser drilling machine and process identification. At the meeting, six two five five, the National Taiwan University, four one hundred factory, one hundred and thirty plants, 430 plants and other units made an introduction, and six 65 developed GJK-1 laser drilling machine and process Identification. Laser drilling is a new method, especially for a variety of soft and hard materials processing φ1 mm precision small holes, small slit effect, to solve the aeronautic engine air-cooled blades, nozzles and other small hole precision machining Practical problems.
