由于切断工序在管子和棒料工件的切断中应用很广,因此切断刀的新发展引起了人们极大的关注。有时这些发展从外表上看来差别很小,但其结果却有很大的改进。本文介绍切断刀最新发展的两个实例:一个西南方油田刀具制造厂使用的两种镶C_5(ISO P40)硬质合金刀片的切断刀,其差别是惊人的,新结构切断刀的进给量可提高3(1/2)倍,切削速度可提高2(1/2)倍,结果在切削4140
Due to the cutting process in the pipe and bar workpiece cutting is widely used, so the new development of the cutting knife has caused great concern. Sometimes these developments appear to be very small in appearance, but the results have been greatly improved. This article presents two examples of the latest developments in cutting knives: two cutting inserts with C_5 (ISO P40) carbide inserts for use with a tool plant in the Southwest Oilfield. The difference is staggering. The feed of the new structure cutting knives Can be increased by 3 (1/2) times, the cutting speed can be increased by 2 (1/2) times, the results in cutting 4140
