使用手用钢锯条锯削如工具钢、弹簧钢等材料时,由于所锯材料硬度较高,锯削时使部分机械能迅速转化为热能,所以锯齿极易变钝,有时锯截材料需更换几根锯条,浪费大,工效低。为了适应锯截较硬材料的需要,我们采用了先在锯条前段用比常速快两倍左右的往复速度进行锯削约10个来回,接着在锯条中段按上法锯削,再在后段同样进行锯削,然后又回到前段同样进行锯削,依次类推,不断分段进行快速锯削。这样,虽然同是一根锯条,但如此分段锯削,在每段上的锯
Use hand saws hacksaw, such as tool steel, spring steel and other materials, due to saw the higher hardness of the sawing, sawing some of the machinery can be quickly converted to heat, so easy to blunt serrated, and sometimes saw the need to replace the material cut a few Root saw blade, waste large, low efficiency. In order to meet the needs of sawing harder materials, we used the saw blade before the first paragraph with about twice faster than the normal speed of about reciprocating sawing back and forth, and then press the saw blade in the middle sawing method, and then in the back section The same sawing, and then returned to the front section of the same sawing, and so on, continue to sub-section for rapid sawing. In this way, although the same is a saw blade, but so sawing in sections, sawing in each section
