METHOD FOR INCREASING SERVICE LIFE OF CYLINDER OF PD-10M DOUBLE-FLOW INTERNAL COMBUSTION ENGINE

摘要

FIELD: engines and pumps.SUBSTANCE: invention relates to part restoration industry and can be used at repair of a cylinder of PD-10M double-flow internal combustion engine. Restoration is performed by means of an internal grinding method in two stages on an internal grinding machine with further honed finishing based on additional repair size Dp.p=74.25mm. Rough grinding is performed at the first stage, and finish grinding is performed at the second stage. Processing modes for the above grinding and honed finishing operations are described.EFFECT: providing regular geometry of a restored cylinder and maintaining strength properties of its walls.
