大型轴类件高精度台阶孔的加工方法

Machining Method of High Precision Stepped Hole of Heavy Shaft Parts

通过设计专用工装,选用卧式车床加工,满足了高精度台阶孔的形位公差及尺寸公差;在专用工装上安装钻头后,可实现钻孔功能,解决了大悬伸高精度中心小孔的加工难题。

By designing special tool and selecting horizontal lathe machining,form and location tolerance and size tolerance of high precision stepped hole could be achieved.Special tool with drill could realize drilling function,which solved machining difficulty of big overhanging high precision center small hole.
