二、磨前倾面的方法刃磨大螺旋角蜗轮滚刀,最容易产生的缺陷是:1)在同一排齿的各段刃面上,螺旋角不一致。因而同一排齿上两端前倾面的径向性也会不一致;2)刃磨后的前倾面中部凸出(如图1)。现在我们就来谈谈消除以上缺陷的方法:1.在同一排齿的各段刃面上螺旋角不一致,这往往是表现在同一排齿的两端前倾面径局性不一致,图8是刃磨螺旋角25°30′滚刀时的实际记录,从记录可以看 Second, the method of grinding face to face grinding Large spiral angle hob hob, the most prone to defects are: 1) in the same row of teeth on each section, the helix angle is inconsistent. So the same row of teeth on both ends of the rake face radial will be inconsistent; 2) sharpened rake surface of the central bulge (Figure 1). Now we will talk about ways to eliminate the above shortcomings: 1. In the same row of teeth on each blade surface helix angle inconsistency, which is often manifested in the same row at both ends of the rake face unevenness, Figure 8 is Sharpening helix angle 25 ° 30 ’Hob actual record, can be seen from the record
