“机械工人”1957年第3期的“应用进步式滚刀的经验”一文,对于磨制进步式滚刀的方法作了详细的介绍,现在我再来谈另一种磨制的方法。这种方法是在铲齿车床上进行,但不必制造靠模,所以比较简单。这种方法的具体步骤如下: 1)在滚刀圆周上找好磨削曲线范围内的齿数,沿着螺旋线A的方向,分别是齿1,齿2,齿3……齿17,齿18,齿19等,按照曲线形状(照57年第3期所谈的方法画曲线)量出每个齿顶应磨低的尺寸h_1,h_2,h_3,……h_(l7),h_(18),h_(19) The article entitled “The Experiences of Progressive Hobs”, Mechanical Workers, No. 3, 1957, gives a detailed introduction to the method of grinding progressive hobs. Let me now turn to another method of grinding. This method is carried out in the shovel lathe, but do not have to rely on the model, so simple. The specific steps of this method are as follows: 1) Find the number of teeth in the range of the grinding curve on the circumference of the hob, along the direction of the helix A, respectively, tooth 1, tooth 2, tooth 3 ... tooth 17, tooth 18 , Tooth 19, etc., according to the shape of the curve (according to the method of the 57th year of the third method of drawing curve) out of each tooth top should be worn low size h_1, h_2, h_3, h_17, h_18, , h_ (19)
