圆孔铰刀的等分齿和不等分齿结构问题,曾经发生过不少的争论,大都以不同的实例和理论分析来证明各自结论的可行性。铰孔表面的最终质量与多种因素有关,欲取得理想效果,必须根据具体工艺条件综合分析,针对主要影响因素加以解决才能奏效。“等分齿”和“不等分齿”只是影响因素之一。在某种条件下两种结构的工艺效果明显不 Round hole reamer bisecting teeth and unequal tooth structure problems, there have been many controversies, most of them with different examples and theoretical analysis to prove the feasibility of their conclusions. The final quality of reaming surface with a variety of factors, in order to achieve the desired effect, must be based on a comprehensive analysis of specific process conditions, to address the main influencing factors to be resolved to work. “Equal points” and “Unequal points” are just one of the influencing factors. Under certain conditions, the effect of the two structures is obviously not
