缸盖气门座圈及气门导管粗精加工方案研究

摘要

As the valve seat ring with high hardness of powder metallurgy material,high precisely request of machining,the tool life is too short,the new pre and finish cutting strategy was presented without increasing the tool amount and machining cycle time.To realize valve seat ring machining with much longer tool life,less tool change frequency and more stability.%针对粉末冶金气门座圈和气门导管硬度高,加工精度要求高,刀具加工寿命低等特点,在不增加刀具数量和加工节拍的基础上,提出缸盖气门座圈的粗精加工解决方案.大幅提高刀具寿命,减少换刀频次,保证加工稳定性.
