我门使用Y7125齿轮磨床修磨圆盘式剃齿刀。由于剃齿刀是螺旋齿,齿宽方向的一端先同砂轮接触,然后才全长接触,同时由于刃磨时切削力不等,所以后退出砂轮的一端往往出现顶切现象。因此,在齿宽上各个不同剖面里(如图1),齿形误差各不相等,有的甚至超出允许公差范围。图2所示即为其剖面齿形,其中AA剖 Our door uses the Y7125 gear grinder to sharpen the disc shaving cutter. As the shaving cutter is a helical tooth, one end of the tooth width direction is contacted with the grinding wheel first before being contacted with the full length. At the same time, due to the cutting force when sharpening, the top cutting phenomenon often appears at one end after the grinding wheel is withdrawn. Therefore, in the different tooth profile in different sections (Figure 1), the tooth-shaped errors are not equal, and some even beyond the allowable tolerance range. Figure 2 shows the profile of its profile, which AA section
