北京第二工具厂在生产圆管锯片过程中,使用φ350毫米回转工作合,在万能铣床上进行分齿加工,由于分度时工作台大小游标刻线较细,往往造成操作误差,影响产品质量,甚至报废。为此,对回转工作台进行了改装,取消原有工作台手轮,在手轮轴上装一套分度头(图1),利用分度盘上的分度 Beijing Second Tool Factory in the production of circular pipe saw blade process, the use of φ350 mm rotary work together in universal milling machine for sub-tooth processing, as a result of indexing table size cursor thinner, often resulting in operational errors affect the product Quality, or even scrapped. To this end, the rotary table has been modified to cancel the original table hand wheel, hand wheel shaft installed a set of indexing head (Figure 1), the use of sub-indexing plate
