Quality Questions Study Of Diesel Engine Cylinder Block Bore And Cylinder Bore Machining

With the analysis of the causes to the cylinder bore deformation and wear out, all thefactors to the causes in the course of machining and resolving method are discussed in allways, which are for the accuracy assurance of cylinder bore and bore top groove, and thephenomena of the problem easily happened in the course of machining, including assuringthe design, application, maintenance of the machines from the unstable of the top groovedepth and chattering while machining;Fixture design, improvement adjustment;Toolcartridge application and adjustment;and machining data set up description. In addition,the suggestion for the machine function selection on how to form the plateau honing netvein for the cylinder liner theory and practice also the attention items are given for thefixture design and application;much practice experience gives the demonstration that inorder to get quality machining surface, the machine tool, process data, honing stone aswell as honing oil are very critical to the honing quality .In the end, the conclusion of theeasily happened mis-operation for machining the cylinders(such as cylinder bore matchclearance, roughness etc.) is given.
