为了提高尖齿滚刀的精度,可以在它镶齿后进行刃磨(苏联发明证书1087309)。现举例说明整体滚刀的刃磨情况,这种滚刀是倾斜安装硬质合金刀齿并增大了刀齿不工作顶刃的负前角γB。该滚刀近来在高硬度齿面圆柱齿轮的半精和精切加工中得到越来越广泛的应
In order to improve the precision of the sharp-edged hob, it can be sharpened after its insertion (Soviet Union invention certificate 1087309). An example of sharpening of an overall hob is given as an example. The hob is tilted with a cemented carbide cutter tooth and increases the negative rake angle? B of the cutter no-working tip blade. The hob has recently been more and more widely used in semi-precision and finishing machining of high-hardness spur gears
