 Abstract
The analysis of the machine - tools produced in the last years reveals that their development tendencies are oriented in the direction of the productivity increasing and of the processing accuracy.
The paper presents a modality of establishing operational reliability of the normal lathe having as calculus criterion the decreasing of made parts execution accuracy.

 Rezumat
Analiza maşinilor-unelte fabricate în ultimii ani relevă că tendinţele de dezvoltare ale acestora sunt orientate în direcţia măririi productivităţii şi a preciziei de prelucrare.
Lucrarea prezintă o modalitate de stabilire a fiabilităţii operaţionale a strungurilor normale având drept criteriu de calcul scăderea preciziei de execuţie a pieselor confecţionate.
