对小型曲面板材零件,下料时因为只能直线切割,要留有很大的加工余量很难进行套切,所以浪费了原材料。节料锯条是将普通钢锯条在砂轮机上修磨,成附图所示的形状,能锯切半径为10mm的各种曲线。修磨时,要注意不要让锯齿部分退火,以免影响使用性能。又由于锯条的宽度减少,强度降 For small curved plate parts, blanking because it can only be straight-cut, to leave a lot of allowance is difficult to set the cut, so wasting the raw materials. Knife Saw Blade is a common hacksaw blade grind on the grinder, into the shape shown in the figure, can saw a radius of 10mm of various curves. When grinding, care should be taken not to allow serrated annealing, so as not to affect the use of performance. And because the width of the saw blade is reduced, the intensity drops
