沈阳铁路局苏家屯机务段,在加工小批量四方、六方螺钉、螺帽等多边形标准件中,为解决设备不足,满足不了生产需要的问题,自己动手,制造并使用了车多边形工具(见图)。这种工具装卡在普通车床上,可代替铣床和刨床,加工多边形工件。经过生产实践考验,使用这种工具加工,生产效率高。 Shenyang Railway Bureau Sujiatun locomotive depot, in the processing of small quantities of square, hexagonal screws, nuts and other polygon standard parts, in order to solve the equipment shortage, can not meet the production needs of the problem, do it yourself, to create and use the car polygon tools (see Figure). This tool installed card in the ordinary lathe, milling machine can be replaced and planer, processing polygon workpieces. After the test of production practice, the use of this tool processing, high production efficiency.
