Abstract
In this paper thin-walled part deformation during finishing turning process caused by gripping force of hydraulic lathe chuck was investigated. Bearing ring was taken as an example of thin-walled part undergo finishing turning operation. Finite Element Method (FEM) was used to define the deformation of examined part. The aim of presented research was to compare the deformation of bearing ring caused by gripping force of hydraulic 3-jaw chuck and 6-jaw chuck for different values of total gripping force. The data obtained from conducted simulations allowed to evaluate the influence of gripping force on machining part deformation which is directly related with its geometrical accuracy.

Summary
Machining is one of the most common methods for producing parts for different branches of industry. There is a group of parts, which production is associated with high technological difficulties. Thin-walled parts, which are highly susceptible for deformation, can be counted in among these parts. The following factors leads to deformation of thinwalled parts during machining: gripping force, cutting force and heat generated during process [1, 2]. In this paper bearing ring deformation, during finishing turning of inner diameter, caused by gripping force of hydraulic chuck was investigated. In this purpose Finite Element Method was used. The drawing of analysed bearing ring is presented in fig. The drawing of analysed bearing ring is presented in fig. 1
