本人曾在本校学报上刊登过关于圆刀片密齿端铣刀的探讨文章,主要是对该刃具进行理论分析,即确定铣削图形、切削几何参数、切削宽度,和有刃倾角时圆刀刃在基面上的投影,任意点的曲率半径及曲率中心等.而本文介绍这种铣刀的设计方法、试验结果、优点及用途. 一、结构设计圆刀片阶梯铣削密齿端铣刀装配结构如图1。铣刀由铣刀体、圆刀片、M10球头螺钉、M10×14六角螺钉、弹簧垫圈、垫圈等七种零件组成。整把铣刀共12个刀齿,按阶梯铣削排列。1、2号为粗铣刀齿,轴向跳动允差相邻两组为±0.07,铣刀一转±0.1;而3号为精铣刀齿,轴向跳动允差相邻两组为±0.01,铣刀一转±0.015。
I have published in my school journals on the round blade dense tooth end milling cutter articles, mainly for the cutting tool for theoretical analysis, that is, to determine the milling graphics, cutting geometry, cutting width, and cutting edges with a round blade at the base The surface of the projection, the radius of curvature of any point and the center of curvature, etc .. And this article describes the design method of this cutter, test results, advantages and uses.First, the structural design round blade step milling tooth end mills assembly structure shown in Figure 1. Milling cutter from the cutter body, round blade, M10 ball screws, M10 × 14 hex screws, spring washers, washers and other seven components. The entire cutter a total of 12 teeth, arranged by ladder milling. No. 1 and No. 2 are rough milling cutter teeth, the allowable axial runout is ± 0.07 in the adjacent two groups and ± 0.1 in the milling cutter; while the 3rd is the milling cutter tooth, the tolerance of axial runout is ± 0.01, cutter ± 0.015.
