Questions of precision quality shaping of lathes are examined in this article. Experimental methods of an exactitude estimation of a head slide rotation on parameters of its circular trajectories with and without the application of working loadings are presented. Also questions of running accuracy of a planing tool box, influence of thermal strains of the machine tool on its exactitude are discussed, The scheme of measuring and presetting station and results of measurements on parameters describing exactitude of lathes are presented in conclusion.
