The paper deals with the investigation of exploitation technological efficiency of metall-cutting machine tools. The main goal of this study is to determine more advanced way of choice of equipment and to organize metall-cutting machine tools rational maintenance. Classification of basic and optional evaluative measures is presented in the first part of the paper. The research methodology provides the estimation of exploitation technological efficiency by calculation of the complex evaluative measure. The results of comparative estimation of two metall-cutting machine tools (Okuma LB 4000 EX, CTX Gamma 2000) are presented in the last part of the paper. According to evaluation result, Okuma LB 4000 EX stands at a higher level of exploitation technological efficiency.

Keywords: exploitation technological efficiency, comparative estimation, complex evaluative measure, methodology, data analysis
