套料加工较之正常钻削的主要优点有三:(1)速度快;(2)精度较高;(3)表面光洁度较好。一个需要用扁钻钻孔、两次精镗、然后珩孔的工件,经过套料切削和精珩即可;套料切削速度比整体钻削高得多。美国Hollow Boring公司用一台32吋(813毫米)的镗床改装成一台套料机床,并且装有一个向刀刃供油的压力头(图1)。 The main advantages of nesting compared to normal drilling are three: (1) fast; (2) high precision; (3) better surface finish. A need to drill with a flat drill, two fine boring, and then honing the workpiece, after nesting and fine Heng can; nesting cutting speed is much higher than the overall drilling. The Hollow Boring Company in the United States converted a nesting machine using a 32-inch (813 mm) boring machine and equipped with a pressure head that feeds the cutting edge (Figure 1).
