問:在你刊七卷五期上發表了一篇‘摩擦鋸的研究’報告,它的优點是相当多的。我認为,这个摩擦鋸对我們車間很適用。根据現在的情况,我們的下料鋸切問題,已不能供应整个車間的需要,而鋸条又很不好買。如果利用摩擦鋸,整个問題就可以解决了。但是有这样一个問題:鋼軌在鋸切時,如果要它轉,則在轉時,軌背、軌底、和軌腰之間就要形成了断續。这对锯切是否有影响?如果不轉,切后的表面是否太粗,这个鋸切工作是否能進行?希望能作詳細的解答。山海關桥梁工廠道岔車間 董維成答:關於鋼軌的切断問題,我們考慮过,認为同样是可以轉動切断的。效率質量同样有所提高。我們曾用轉動的方法切断过三角铁,只是所用
Q: You published a report on the study of friction saws in your journal, Volume VII, which has quite a number of advantages. In my opinion, this friction saw is very suitable for our workshop. According to the current situation, we cut the problem of cutting, can no longer supply the needs of the entire workshop, and saw blade is not good to buy. If you use a friction saw, the whole problem can be solved. However, there is such a problem: when the rail is sawing, if it is to be turned, the intermittence will be formed between the rail back, the rail bottom and the rail waist. Does this have any effect on the sawing? If not, is the surface cut too rough? Is this sawing done? Hopefully, a detailed answer will be given.

We used the turning method to cut off the triangular iron, but it was used
