我厂经常大批制造‘棒铣刀’,须要做有顶针眼的活。这些活都必须先打好洋铳眼后,才能用车床制作。但是,在大批打洋铳眼时,本来是用‘划卡’找出中心后,才能打眼。这样,是一头一头的划(每一件须划两回),不但做的慢,而且划出来的活,也不规距,眼也不对中心,对生产数量,就有很大的影响。工友万斧田同志,看到这种情形后,就开动脑筋。创造出快速打铳眼工具。经制造试验后,提高产量三倍多,而且打出来眼又正。又省去了找中心划线的麻烦。现在我把打洋铳眼工具的构造,说明如下: I often plant a large number of manufacturing 'rod cutter', need to do a pinhole live. These live must first hit the yang eye, can use lathe production. However, in the case of a large number of eyeballs, it is only after the center has been identified by using a 'draw card' that it can be achieved. In this way, it is a one-stroke plan (each subject to be traced twice). Not only is it slow, but it is also not subject to discrepancies or deviations. It does not center on the production volume and has a great impact on the production volume. After seeing this kind of situation, our workers, Comrade Emma Honda, start their brains. Create a quick hit counter tool. After the manufacturing test, increase the output more than three times, and hit the eye and positive. Also saved the trouble of finding a center crossed. Now I'm going to hit the structure of foreign eye catcher, described as follows:
