Development of new methods of improving machine units in order to use the potential (strength margin) to increase the productivity of machining on lathes. The object of research is the subsystems of lathes of the traditional structure, which have the greatest impact on the productivity of processing. The subject of research - physical-mechanical and energy processes that occur during different modes of operation in the subsystems of lathes. The work is aimed at solving problems of improvement and modernization of metal-cutting lathes. Aspects of forecasting the parametric reliability of spindle GSP are determined: system, functional, time and design-technological. The discrete Fourier analysis of the spindle beating curve allowed to fully diagnose the quality of SW assembly and the influence of individual errors on the accuracy and quality of machining during longitudinal turning. On the basis of theoretical and experimental researches the patent of Ukraine for the invention 116050 is received. Spindle knot of the machine. As a result of designing and modeling of power characteristics of lever drives of a clamp of lathes the patent for the invention of Ukraine № 120959 is received.
