多头滚刀能够显著提高渐开线圆柱齿轮及花键轴的加工效率,更重要的优点是,在任何型号的滚齿机上,都可以使用多头滚刀。但多头滚刀过去和现在主要用于大模数齿轮精滚或精插前的粗加工。很少用于圆柱齿轮 Multi-head hob can significantly improve the processing efficiency of involute cylindrical gears and spline shaft, more important advantage is that in any type of hobbing machine, you can use multi-head hob. However, the hob has been used mainly for the roughing of large modulus gears or roughing before fine insertion. Rarely used for spur gears
