C618D和C618车床上都有2～3个进刀用的分度圈,分度圈上的刻线通常是在铣床上加工的(指设备差的工厂),不但生产率低,而且不能保证质量,因而远不能适应我厂成批生产的要求。在大跃进中,我厂蒋善庆、邵邦富和石磊三位师付共同研究,利用一台废的小车床改装成一台高效率的刻度机,并命名为“革新牌”。 The C618D and C618 lathes have 2 to 3 indexing rings for infeed, and the engraved lines on the indexing ring are usually machined on a milling machine (referring to poorly equipped factories), which not only results in low productivity but also can not guarantee the quality, So far can not adapt to our factory batch production requirements. During the Great Leap Forward, three of our factory, Jiang Shanqing, Shao Bangfu and Shi Lei, studied together and converted them to a highly efficient scale machine using a scrapped lathe bed and named it “Innovation Brand.”
