Abstract
Obtaining of the quality of the inner surface of the hydraulic cylinders and its optimization is an urgent problem in the enterprise. The article presents the results of a study to improve the finishing process of deep holes in thin-walled sleeves. The authors used the combination of the cutting process and surface plastic deformation for improving metal processing. The selected main parameters for ensuring the quality of the surface are roughness index and the value of internal stresses in the surface layer of hydraulic cylinders. To determine the hardening depth of the inner surface of the deep hole of the liner, the oblique thin section method was used. A mathematical model of the combined processing was obtained. The research results make it possible to recommend combined hole processing that combines cutting and plastic deformation. The results obtained in this work will improve the processing of deep holes of hydraulic cylinders, and the developed mathematical model has practical and theoretical scientific value.
