插齿刀前面的精磨对於制作质量较好的齿轮有很重要的意义,因为插齿刀刀刃的情况可以直接影响齿轮的牙齿外形。此外插齿刀所切下的切屑非常细,所以提高插齿刀前面的加工质量时,亦能提高其耐磨性。 作者在磨过插齿刀以後,会用生铁轮精磨插齿刀的前面,结果用它插出的齿轮,牙齿的光 Gear grinding in front of the gear for the production of better quality gear is very important, because the gear cutter blade edge of the tooth shape can have a direct impact on the gear. In addition, the shavings cut by the sharpening cutter are very thin, so when the processing quality in front of the shaper cutter is increased, the wear resistance can also be improved. After grinding the gear shaper, the author will grind the front of the gear shaper with a pig iron wheel. As a result, the gear with which it is inserted and the light of the teeth
