文章介绍了新型反锪刀、粗铣用花键滚刀的结构;分析了中心孔60°锥面的误差对工件精度的影响和尺寸的控制方法;还分析了圆弧代替渐开线齿形超差的原因及可能超差部位,并介绍了修磨方法。
In this paper, the structure of a new type of reverse trowel and a roughing mill with a spline hob is introduced. The influence of the error of the 60 ° cone of the center hole on the workpiece accuracy and the control method of the size are analyzed. Causes of ultra-poor and possible ultra-poor parts, and introduced the grinding method.
