000021328 520__ $$2eng$$aWorking accuracy is one of the crucial parameters of every machine and especially of machine tools. This is the reason why checking and computation of the primary parts of all new designed lathes has to be performed to ensure the optimal rigidity, dimensions and weight. This paper describes the computation and results of the strength evaluation, static stiffness assessment and checking of contact normal stress in the guideways of a tailstock of a universal centre lathe. To acquire all of these values, a computation was performed using the finite element method (FEM) in MSC Marc 2011. The computational model was loaded by the maximum forces that were obtained via analytic calculations from the load spectrum of a lathe. The strength evaluations of all individual parts of the lathe were investigated according to two different criteria. Computed values of contact normal stress were compared with maximum pressure loads. Displacements of the centre of the tailstock were found by using this FEM computation. The stiffness was calculated in three mutually orthogonal directions from these displacements and loading forces.
