气缸盖的结构比较复杂,在其上的导管孔和气门座锥面加工精度要求很高,难度较大,加工中对热、振动以及各种应力变化十分敏感。为保证气缸盖的加工精度,在加工过程中采取一些诸如隔离热源、强制冷却、隔振等有益的措施是必需的。但是,采用刚性好、高的加工稳定性、高效率的机床以及领先一步的刀具技术更为重要,它是最终保证气缸盖加工精度的关键所在。 Cylinder head structure is more complex, in its catheter hole and valve seat cone surface machining accuracy is very high, more difficult, the processing of heat, vibration and a variety of stress changes are very sensitive. In order to ensure the machining accuracy of the cylinder head, some beneficial measures such as isolation heat source, forced cooling, vibration isolation and so on are necessary during the process. However, the use of rigid, high machining stability, high efficiency of the machine tools and one-step cutting tool technology is more important, it is ultimately the key to ensure the accuracy of cylinder head machining.
