Abstract The article deals with the examination of the state of the ball track of the heavy mining machine ZP6600/Z79. It gives results of material exams which were taken on given samples and describes the progress and results of the numerical computation of the state of tenseness by finite element method of the bottom part of the ball track when it touches the ball.

The destruction of the center hole becomes a big accident in lathe processing. This paper advocates the safety standard concerning the center hole. It is a simulation concerning the center hole by using of experimental mechanics and computational dynamics together. This study is composed by some analysis methods. The method is an isochromatic line, an isoclinic line by the photoelastic method, method of caustics, and two dimension finite element method, a tridimensionality finite element method. In the photoelasticity method, it was done that the test specimen model by which the real machine parts straight side direction section dimensional standard was copied was done. The test specimen model dimensional standard used by the photoelastic method was analyzed in two dimension finite element method. The model by which real machine parts was faithfully reproduced was analyzed in the tridimensionality finite element method. In method of caustics, an artificial crack was inserted in the test specimen model. The fracture process of the center hole was understood as a research result, and the equation to obtain the maximum stress was obtained. It is forecast that safety in the processing with the lathe can be secured if you follow the research result.
