Simple machining of large eccentric shaft and angular eccentric shaft

In the absence of special processing equipment, the eccentric shaft is typically machined on a lathe. The machining principle is basically the same, that is, the axis that needs to be machined to the eccentric portion is corrected to a position that coincides with the axis of rotation of the lathe spindle. 1. Simple processing of large eccentric shaft When encountering eccentric shaft machining with large eccentric distance, long length and large batch size (as shown in Figure 1), conventional processing method on horizontal lathe: preparation length is 265mm, ( ?) 180mm round steel, → machine both ends to 259mm long → scribing to find the position of the two axes
