Background
The turning machining has the advantages of simple equipment, simple and convenient operation, high machining efficiency and the like, and can be widely applied to the machining of the inner circle and the outer circle of the rotary workpiece. However, in machining, the requirement of the turning radius of some cylindrical tables is often large, workpieces are short and small, the auxiliary rod is needed to lengthen the workpieces when the parts are machined on a horizontal lathe, and the lengthened parts can cause the lathe to vibrate due to large eccentric amount during rotation, so that the machining precision of the workpieces is affected, and a lathe spindle is easily damaged; in addition, the single-arm extension mode of the auxiliary rod can only process one workpiece at a time, and the production efficiency is low. In addition, for a workpiece requiring a relatively small turning radius, an eccentric sleeve or an eccentric clamping tool is adopted to perform turning and eliminate the vibration problem caused by eccentricity, but the turning is only limited to the workpiece with the relatively small turning radius, and if the turning is applied to the workpiece with the large turning radius, the eccentric sleeve is too large, the cost of the tool is high, and therefore the application limitation is large. Therefore, the workpiece is eccentrically arranged on a turntable of a vertical lathe for processing, although the workpiece is eccentric, the turntable of the vertical lathe has stronger rigidity than a main shaft of a horizontal lathe, so that the adverse effect caused by the eccentricity can be reduced or even ignored, and the processing of the workpiece can be met; however, because such workpieces are small, the machining cost of using a vertical lathe is high, and there is no way to use such a method for a unit without a vertical lathe.
