摘要
根据零件对材料和形位公差的特殊要求,自制过程中,在热处理工艺和机加工工艺方面进行了多次试验,最终确定的工艺方案加工出的气门导管完全满足图纸要求。自2003年装机使用以来,效果非常好,已完全解决了气门导管偏磨等质量问题。
In order to meet the specifications for parts,extensive tests were made and the technique has finally been developed.The valve guides made with our technique having successfully been used since 2003.
