Efficient Machining of Cylinder Head Injector Hole of Marine Diesel Engine
Yin Bing，Wang Fei
Abstract:Cylinder head is one of important spare parts of marine diesel engine，and it′s typically dubbed as the bottleneck section to restrict improving the production efficiency of marine diesel engine；while oil ejector hole processing holds the key to the cylinder head processing.This thesis makes a detailed analysis on the structural features of oil ejector holes；based on that，it concludes a complete processing plan and cutting parameters.A whole set of nonstandard cutting tools has been designed and developed which is also on trial by customers on spot in the end. It proves that vibration in the middle of large diameter and deep hole processing can be addressed if the cutting tools and processing plan mentioned in thesis are used；and additionally，it will make production efficiency of cylinder head of marine diesel engine a leapfrog and the spares parts totally comply with the drawings.
