近二十年来,国外机械行业普遍用带锯床切断下料,如美国用带锯下料高达80％以上,西德和日本都在50％以上。相比之下,在这些工业比较发达的国家里,圆锯床和弓据床的使用量都有不同程度的下降。带锯床之所以发展很快,深受用户欢迎,成为四大类锯床(圆锯床、弓锯床,砂轮片锯床和带锯床)中的佼佼者,是因为它有如下几个明 In the past two decades, the foreign machinery industry has used band saws to cut materials. For example, the United States uses band saws to cut materials up to 80%, and West Germany and Japan have more than 50%. In contrast, in these industrially advanced countries, the use of circular sawing machines and bow beds has declined to varying degrees. The reason why the band sawing machine has developed rapidly is welcomed by users. It has become a leader in the four major types of sawing machines (circular sawing machines, hack sawing machines, grinding wheel sawing machines, and band sawing machines) because it has the following advantages:
