随着工業的發展,金屬材料的鋸切工作变成一个很重要的問題。目前,很多工廠仍然只能使用机械鋸(弓鋸、圓鋸等),生產率受到一定限制,鋸断一根材料往往需要很多的時間。遇到工作多時,更是难以完成任务,影响生產。並且,在鋸切工作中,要消耗大量的鋸片、鋸条。一根普通鋸条在“250”弓鋸上使用,鋸切直徑75公厘的圓铁料,还切不到七、八次,鋸齒已被完全磨損,失去了锯切能力。在鋸切中,一次比一次所需的時間也都更長一些,生產率随着鋸齒的磨損程度而迅速下降。对一些硬度较高的材料來說,更是难以锯断。鋸条大量的消耗,在大規模的經济建設中是一个很大的
With the development of industry, sawing of metal materials has become a very important issue. At present, many factories still can only use mechanical saws (bow saws, circular saws, etc.) with limited productivity. Cutting a single piece of material usually requires a lot of time. Encountered a long time, it is difficult to complete the task, affecting production. And, sawing work, to consume a large number of saws, saw blades. A normal saw blade is used on a “250” bow saw, sawing a round iron with a diameter of 75 mm, but less than seven or eight times. The saw teeth have been completely worn and lose their sawing ability. In sawing, the time required is longer than once, and productivity decreases rapidly with the wear of sawtooth. For some high hardness materials, it is more difficult to saw off. Saw a lot of consumption, in large-scale economic construction is a big one
