反向滚铣工艺使用标准齿轮加工机床,但要改变通常刀具和工件的安装,即将刀具安装在工件轴上,而将工件毛坯安装在刀具轴上。蜗杆材料为EN36镍铬合金钢(硬度为RC10～12,切削后表面淬火到RC56～60)。蜗杆的形状使切削时形成满足要求的切削后角,因而刀具可设计成没有后角的。这样可在重磨刀刃之后仍保持刀具外径不变。圆盘刀具用A1S1T4高速钢制造,淬火回火到RC64。刀具齿经精确成形磨削,周节精度为0.003
The reverse hobbing process uses standard gear to machine the machine, but to change the usual tool and workpiece setup, the tool is mounted on the workpiece axis while the workpiece blank is mounted on the tool axis. Worm material EN36 nickel-chromium alloy steel (hardness of RC10 ~ 12, surface hardening after cutting to RC56 ~ 60). Worm shape so that cutting to form the cutting angle to meet the requirements, so the tool can be designed to have no relief angle. This will remain the outer diameter of the tool after resharpening the blade. Disc cutter with A1S1T4 high-speed steel, quenched and tempered to RC64. Accurate shaping of the tool tooth grinding, the pitch accuracy of 0.003
