各类滚刀刃磨,通常是在滚刀刃磨机床上或专用夹具上进行,但往往不能满足有特殊要求的滚刀(例如大螺旋角、杆式蜗轮滚刀和小直径滚刀)。我们用下述的靠磨方法,在生产实践中刃磨特殊的杆式和孔式蜗轮滚刀,达到图纸要求的精度。靠模是一个带螺旋槽的圆柱体(图1),其导程、方向等参数与被磨滚刀一致,外径可不相同。靠模的长度应比滚刀工作部分长一些,以便在砂轮退出时,靠模的工作面仍然靠紧工具磨床支架的支板上。靠模可在万能铣床
Various hob sharpening, usually on hobbed sharpening machines or special fixtures, often can not meet the special requirements of the hob (such as large helix angle, rod worm hob and small diameter hob). We use the following by the method of grinding, grinding in the production of special grinding rod and hole worm hob, to the accuracy of the drawings required. By the mold is a spiral groove cylinder (Figure 1), the lead, the direction and other parameters and be hobbing knife consistent, the outer diameter may not be the same. The length of the abutment should be longer than the working part of the hob so that when the wheel exits, the abutment of the abutment still rests against the support of the tool grinder support.
