我们改进了一双刀架用来加工齿轮圈,效果很好。开始时用单刀切断,转数为1.5转/分,但受走刀量的限制,不能自动走刀,只好手摇进刀,因此不但劳动强度大而且效率低,切一个工件就需要十几小时。改进后用双刀切,转数为3转/分。由于两把刀同时切,第二把刀先切出了一个槽沟,使第一把刀的切削条件大为改善(如切刀刀尖形状图)。不但可以用自动走刀,而且可以把走刀量加大到0.33毫米/转消灭了振动现象,这样就使切断工时缩短到2小时左右,从而提高效率4倍多,解决了大 We have improved a pair of tool holders for machining gear rings and works well. Starting with a single knife off, the number of revolutions of 1.5 rev / min, but by the amount of walking restrictions, can not automatically take the knife, had to hand-feed, not only labor-intensive and low efficiency, cutting a workpiece will take more than ten hours . Improved with double knife, the number of revolutions to 3 rev / min. Since the two knives are cut at the same time, the second knives cuts a groove first, which greatly improves the cutting condition of the first knives (such as cutter nose shape). Not only can you use the automatic knife, but also can increase the path of the knife to 0.33mm / rev to eliminate the vibration phenomenon, so that the cutting work will be shortened to 2 hours or so, so as to improve the efficiency of 4 times and solve the large
