在插床上成批加工键槽宽度大于30mm以上,且长度长、公差值小的键槽,用单刀单面加工容易造成键槽上宽下窄,难以保证质量。为此,我们设计了双刀插大键槽刀杆,用于精插键槽。妇满构由刀杆1、插刀2和6、压块3、垫圈4、螺栓5组成。使用时,首先根据键槽宽度的大小,确定刀杆上a、b尺寸(图2),将 Slotted in the slot on the keyway width greater than 30mm or more, and the length of the small keyhole tolerances, with a single-sided single-sided processing likely to cause the keyway on the wide and narrow, it is difficult to ensure quality. To this end, we designed a double-knife insert large keyway shank, for fine plug keyway. Woman full by the cutter 1, 2 and 6 knife, briquetting 3, washers 4, bolts 5 composition. Use, first according to the size of the keyway, to determine the a, b size (Figure 2), the
