在孔内键槽(图1)的加工中,批量生产通常是在拉床上拉出,单件小批量生产一般是在插床上加工。插床加工键槽其对称度的保证一直缺乏有效的办法。为此,我们制作了对刀工具(图2),可以较容易地保证键槽对称 In the hole keyway (Figure 1) processing, the mass production is usually pulled out on the broaching machine, a single small batch production is generally processed in the slot. Slotting keyway its guarantee of symmetry has been the lack of effective ways. To this end, we made a tool for the knife (Figure 2), you can more easily ensure the keyway symmetry
