The article is devoted to the achievement of the maximum wear resistance of the cylinder mirror of a diesel engine by technological provision of a given dimensional accuracy and geometric shape of the cylinder mirror, as well as roughness parameters in accordance with a given Abbott diagram. The solution of the problem is complicated by the inhomogeneity of the structure of the metal of the casting and the geometry of the outer surface of the cast cooling fins of the cylinder, which leads to variable stiffness and inconstancy of elastic deformations when cutting the cylinder. The problem was solved by optimizing the structure of the technological process and replacing the equipment with a new, more rigid and accurate one.
