Process Technology Research On Valve Seat Ring And Valve Stem Guide Hole Of Cylinder Head

Along with the quick forward development of society, the living standard of people is constantly raised, and the requirement to the various capabilities of automobile of people is also more and more higher. Among them motive force and safe nature of automobile and emission capability have become the major content that people are concerned about. Except possesses the design structure of first-in, the process quality of each parts of automobile is also giving play to the utmost importance effect. As the nucleus parts of automobile, the process quality of the parts of engine is the foundation of whole automobile process. And cylinder head being the part of one of major part on the engine, his process precision influences very the key to the capability of automobile, especially the good or bad of the process precision of valve seat ring and valve stem guide hole of cylinder head the will directly influence automobile realizing of mentioned above capability.This text started with the process precision of valve seat ring and valve stem guide hole of cylinder head and the process precision being to the influence of engine capability, by way of anglicizing major factor to influence the process precision, and studies and comparison on the home and abroad several kinds process technology of valve seat ring and valve stem guide hole of cylinder head.Therefore analyses goes out that the most effective and reliable technology method of processing valve seat ring and valve stem guide hole is gun-boring-finish turning new technology. Again according to practice produces of the gun-boring-finish turning process new technology, verify that this new technology is fit for being used very much at large quantities of capacity of cylinder head producing and gain very high process precision of valve seat ring and valve stem guide hole. At the same time what it is only constantly uses new technology, new technology, new material and new concept can suit the society requirement that constantly changes and constantly rises to the explanation.
