Subject of research - the relationship of design and technological factors centreless-grinding operations pro-cessing surfaces rolling bearing parts of performing intermittent centreless grinding process parameters and quality of polished surfaces. The aim is to improve the efficiency of grinding operations and stabilize the quality parameters de hoists bearings for abrasive cutting operations by creating scientific and practical recommendations for improving the pro-cess, the introduction of high-technology intermittent defect-free sanding in terms perenalahodzhuvalnoho bearing serial production. Research aimed at improving the performance of bearings, methods for in-process pravlenoho influence and control of automated processes in perenalahodzhuvalnoho bearing production. On the basis of theoretical and experimental studies of the methodological basis for the creation of effective methods intermittent grinding circles, ensuring increased productivity and accuracy by reducing teplonapruzhennosti in the cutting zone while increasing the stability of the grinding wheels. The technology for machining parts bearings in grinding operations intermittent grinding wheel to lower the required level contact temperature in the cutting zone. The practical significance of the results of the work is to improve the parameters of the abrasive cutting tool and establishing rational modes of treatment, to improve the physical and mechanical properties of machined surfaces, avoid prypalyuvan, microcracks form errors and increase efficiency of the grinding process in terms of mass and large-pla-bnytstva. The methodological basis of research is a systematic approach to the definition of the research object - pro-cesses grinding surfaces of rolling bearing parts intermittent abrasive perenalahodzhuvalnoho in terms of production based communications technology factors of macro parameters and microgeometry surface and performance parts bearings. Based research to meet the challenges of research was the general provisions manufacturing engineering, theory of cutting materials and mathematical tools of analysis and synthesis to simulation parameters microrelief surfaces of revolution in the process of formation in machining operations; oscillation theory, harmonic analysis to study the mechanism of vibration bearings reasons that cause them; mathematical statistics, optimal control, theory of automatic process control grinding; methods of numerical integration of differential equations; apparatus Laplace transforms, Taylor - modeling for machined surfaces irregularities, they develop methods of vibration and polishing process identification; methods of planning the experiment - to conduct experimental research, analysis and processing of experimental results. To analyze the geometric structure of the surface, and to study the parameters of the form deviation was used modern automated metrology equipment - automated Research Center Talyskan - 150 of managing Map universal program for research mikrotopohrafiyi surface in 3D system. For the harmonic analysis of surface rotation - MWA automated installation of 160V. As a result of research on this topic is developed and put into production technology for defect-free progres-sive grinding roller parts intermittent grinding wheels, thus improving the efficiency of operations machining parts bearings, stabilize the quality and performance of roller bearings.
