The invention discloses a finishing rounding method for sliding bearing bushing production. The method is used for performing finishing rounding on a rounded rough bushing and comprises the following steps of firstly performing finishing stamping on the rounded rough bushing, secondly performing stress relief annealing heat treatment on the stamped bushing, and finally taking out the bushing after the bushing is cooled. According to the method, the technological process for finishing rounding machining of the bushing is simple, the automation degree is high, the production efficiency can be effectively improved, stamping finishing is used for replacing various kinds of grinding finishing on the bushing in traditional finishing machining, the machining cost is reduced, and the precision and quality of the bushing are improved through stress relief annealing heat treatment. 本发明公开了一种滑动轴承衬套生产用精整圆方法，通过对整圆后的粗糙衬套进行精整圆，包括以下步骤：首先将整圆后的粗糙衬套进行精整冲压，其次对冲压后的衬套进行去应力退火热处理，最后等待衬套冷却取出。本发明中对衬套精整圆加工的工艺流程简单，自动化程度高，能有效提高生产效率，利用冲压精整
