190柴油机曲轴数控铣削加工的分析探讨

曲轴是发动机的主要零件,其加工质量和加工效率直接影响发动机的工作性能和制造。曲轴粗加工采用CNC外铣加工工艺,使工件的加工精度、适应多品种生产的柔性和质量的稳定性都有了明显的改善。我厂引进了两台数控曲轴外铣铣床,特别适合于那些对平衡块侧面需要加工、轴颈没有沈割槽的曲轴。其较之车削、内铣等工艺,具有更高的生产效率。以济柴190型柴油机曲轴加工为实例,简要讲述了用数控曲轴铣床进行曲轴粗加工、半精加工的铣切工艺过程步骤和优点。

Analysis of 190 Diesel Engine Crankshaft Milling

The crankshaft is one of the main parts of the engine, the machining quality and efficiency directly influences the working performance and it manufacturing engine. Crank rough machining of a method using CNC. milling process, the work piece machining accuracy, adapt to the stability of the variety of the production flexibility and quality are improved obviously. I plant the introduction of two sets of CNC Crankshaft Milling Machine, especially for those who need to balance block side processing, shaft neck not Sheen cutting groove of cranl~aft, It is turning, milling process, has higher production efficiency. Based on the 190 diesel engine crankshaft machining for example this paper briefly describes the crank rough machining, semi finish machining with CNC Crar~kslaaft Milling machine milling process steps and advantages.
