苏联布良斯克运输机械制造研究所研究了能量达30焦耳的脉冲辐射激光器,能在磁继电器衔铁座装置上钻小孔,钻孔直径为0.8～1.0毫米,深度为3毫米。继电器座上的盲孔被通孔所代替,这是从板材下料时,借助与其它孔一起制成的两个工艺孔来实现的。激光钻孔的深度由工艺孔到继电器座端部的距离来确定,为了3毫米。激光束聚焦在继电器座的端面上,为了 The Soviet Union Bryansk Institute of Transportation Machinery Manufacturing has studied pulsed radiation lasers up to 30 joules in energy and can drill small holes in magnetic relay armature units with drill holes of 0.8 to 1.0 mm in diameter and 3 mm in depth. Blind holes in the relay housing are replaced by through holes, which are obtained from the sheet material by means of two process holes made together with the other holes. The depth of laser drilling is determined by the distance from the process hole to the end of the relay socket, for 3 mm. The laser beam is focused on the end face of the relay holder, in order to
