这一讲重点谈谈不重磨车刀的结构。我们经常听到很多同志问,哪一种车刀结构好?我们认为,衡量某一种不重磨车刀结构的好坏,主要有下列几点:一夹紧刀片要牢靠刀具在长期使用中,刀片不应发生松动现象,即使是在有冲击地间断切削工件的情况下,也不会产生松动。二装卸和调换刀片方便不重磨刀具的结构,除了刀片被夹紧要牢靠外,还要使装卸和调换刀片方便,这样,加工时辅助时间就会缩短。

This talk focuses on the structure of non-restoring turning tools. We often hear many comrades ask which type of turning structure is good? We think the measure of the quality of a certain kind of non-restoring turning tool mainly includes the following points: A clamping blade should be firmly supported by the cutting tool for a long time , The blade should not be loose phenomenon, even in the case of intermittent cutting the impact of the case, it will not produce loose. Two loading and unloading and replacement of the blade Convenient not to regrind the structure of the tool, in addition to the blade is firmly clamped, but also to facilitate the handling and replacement of the blade, so that auxiliary time processing will be shortened.
