以前我厂在加工柴油机气缸盖进排气阀口时,使用如图1所示的刀具,采用压装好的气门导管导向,万向节头联接,在立式钻床上加工。精绞后在研磨机上配研。用配研的凡尔着色检查,阀线应全部着色(产品图纸对气阀口与导管孔中心线的不同心度要求小于0.1毫米)。但是,这一要求一直没有达到,不能保证产品质量。另外,在立式钻床上一次铰一个孔,劳
Before I plant processing diesel engine cylinder head into the exhaust valve port, the use of the tool shown in Figure 1, the valve with a good pressure guide catheter, universal joint head joints, in the vertical drilling machine processing. After the fine twist grinder with research. With a study of the Vernal coloring inspection, the valve line should be all colored (product drawings on the valve port and catheter hole centerline of the different degree of concentricity less than 0.1 mm). However, this requirement has not been met, can not guarantee product quality. In addition, the vertical drilling machine reaming a hole, labor
