在机械制造部门中,铰刀是孔加工用的主要刀具之 一。但是多年来,对於铰刀的结构本身,却很少有人去探 计。近来,苏联学者对於机用铰刀的结构方面提出了一些 新的见解,本刊也曾对铰刀齿距问题有过讨论[1][2]。 此外。在哈尔滨量具刃具厂生产过程中,也产生过铰刀由 于齿距不等,以 In the machinery manufacturing sector, reamers are one of the major tools for hole machining. But over the years, very few people have explored the structure of reamers themselves. Recently, Soviet scholars put forward some new ideas about the structure of machine reamers, and we also discussed the pitch problems of reamers [1] [2]. In addition. Measuring Tool Factory in Harbin measuring the production process, but also produced a reamer due to unequal pitch to
