我厂拉刀车间是生产各种形状拉刀的车间。对于成形拉刀,如阳极拉刀、小洞孔拉刀等,因其形状复杂,所以,对它的加工方法也有所不同。如图1、2所示两孔,若用一般方法加工,不仅效率低,而且表面光洁度和精度都达不到要求。如果加工图1孔型,采用图3所示的阳极拉刀来进行拉削;采用图4所示之小洞孔拉刀,加 I plant broaching workshop is the production of various shapes broach workshop. For forming broaches, such as the anode broach, broach broach holes, because of its complex shape, so its processing methods are different. As shown in Figure 1,2 two holes, if the general method of processing, not only inefficient, but also the surface finish and accuracy are not met. If the processing of Figure 1 hole type, using the anode broach shown in Figure 3 for broaching; using the small hole shown in Figure 4 broach, plus
