工件外球面加工有很多方法,我厂汽轮发电机QF-J4-2零件轴瓦,其外球面采取在普通卧式镗床上加工,简单易行。现将该轴瓦加工工艺介绍如下。 1.加工原理 球面可以看作圆周绕直径旋转一周所形成的曲面。那么,回转中心相互垂直的两个圆周运动,其运动合成的轨迹,便可形成球面。据此原理,在卧镗上,同时使主轴和工作台转盘都旋转来加工轴瓦外球面。
Spherical workpiece processing There are many ways, I plant steam turbine generator QF-J4-2 parts, the outer spherical surface to take ordinary boring machine processing, simple and easy. Now the bearing processing technology described below. 1. Machining principle spherical surface can be seen as a circle around the diameter of the surface formed by a rotation. Well, the rotation center perpendicular to each other two circular motion, the movement of the synthetic trajectory, can form a spherical surface. According to this principle, lying on the boring, while the spindle and table turntable are rotating to the processing of the outer spherical bearing.
