Crankshaft machining process

The invention provides a crankshaft machining process, relates to the technical field of crankshaft machining, and realizes that a crankshaft blank is machined into a crankshaft meeting the requirement by adjusting the machining sequence of finish turning of a main journal and rough milling of a connecting rod journal, adjusting of a rolling process, adjusting of a dynamic balance process and changing and adjusting of other machining modes. The problems that although a traditional machining mode can meet the requirement of a finished product, machining steps are complex, the requirement can be met only through repeated machining, and then efficiency is low are solved. 本发明提供了一种曲轴加工工艺，涉及曲轴加工技术领域，通过精车主轴颈与粗铣连杆颈加工顺序调整、滚压工艺调整、动平衡工艺调整以及其他加工方式的改变和调整，实现了将曲轴坯料加工成符合要求的曲轴，解决了传统的加工方式虽然也能达到成品要求，但是加工步骤繁杂，需要反复多次的加工才能达到要求，进而导致效率低下等问题。
