滚齿机上的立柱、滑板由两条三角导轨把它们联接成一体。立柱上的孔和滑板上支架的孔组成一组孔系,要求其对应孔的同轴度精度很高。各滚齿机制造厂的加工工艺大多采用合镗方式,即采用一套镗模、一次装卡加工出两个零件,或先加工出一件后再组装上另一件,加工完毕一次卸下。采用 Gear column on the machine, skateboarding by the two triangular rails to connect them into one. The holes on the column and the holes on the bracket on the skateboard form a series of hole systems, which require high concentricity of the corresponding holes. The hobbing machine manufacturing process most of the boring method, that is, using a set of boring mold, a card processing two parts out of processing, or first processed out of one after the assembly on the other, the processing is completed once removed. use
