我厂经常要加工一些控制柜、电器柜、保险柜之类的产品,这些产品数量少、种类多,故属单件小批量生产,其中主要零部件柜件、面板、仪表盘上往往有很多大小不等的孔。这些孔若小于φ50mm时,可以用麻花钻在钻床上加工,但如果直径大于50mm时,一般面积较大,而且较薄,所以加工就比较困难。 I often plant processing some of the control cabinet, electrical cabinets, safes and other products, these products a small number of different types, it is a single small batch production, including the main components of the cabinet parts, panels, dashboard often have a lot Holes of varying sizes If the holes are less than φ50mm, they can be drilled on the drilling machine, but if the diameter is more than 50mm, they are usually larger in area and thinner, so machining is more difficult.
