在车床上用顶尖顶着加工的各种螺钉、短轴类工件,都须要先钻顶尖孔,而这是一件比较麻烦的事。一般是在工件端面涂上白粉,用划规或内卡来找正,再打洋冲眼,然后钻顶尖孔,这种方法不但效率低,而且质量不易保证。我厂技术员马学文和车工田儒臣共同改进了一种高速打顶尖孔的工具,使用这种工具,可以在车床上不停车连续钻中心孔,节省了辅助时间,提高
In the lathe with a top against the processing of a variety of screws, short-axis type of workpiece, you must first drill the top hole, and this is a more troublesome thing. General is coated with white powder in the workpiece end, with the rules or within the card to find positive, then hit Yang Chong eyes, and then drill the top hole, this method is not only inefficient, but not easy to guarantee quality. Our factory technician Ma Xuewen and trader Tian Ruchen jointly improved a high-speed tool for drilling apical holes. By using this tool, the center hole can be drilled continuously without stopping in the lathe, saving auxiliary time and improving
