The fModern Motor Manufacturing Technology and Application ofhoning Engine cylinder block is the largest and the heaviest parts ofthin-walled box,It is the basis of engine parts, subjecting to variousinternal and external load. The shape accuracy of the cylinder hole andsurface roughness directly affect the engine performance and fuelconsumption. It can be said the accuracy of the cylinder hole is the mostimportant factor, so the forming processing is the most importantprocesses. This paper analyzes the cylinder of the Honing Process，Andcompares with other advanced honing on the international of thedevelopment processes trend.At present, the automotive industry cylinder used in the process:rough boring→semi-fine boring→Fine Boring→honing processingtechnology. Honing is the ultimate form of which cylinder shape anddimensional accuracy of the important processes. With the continuousdevelopment of the automobile industry and the level of the continuousimprovement of equipment, has been honing technology development. Can generally be divided into the following process: the original honingtechnical manual→traditional automatic honing technology→flat-toppedhoning technology→slide honing technology→laser honing technology.In this paper, on the final processing cylinder honing process described indetail.
