Improving the Surface Quality of Holse of Composite Wear Resistant Sliding Bearing for Printing Machines Taking into Account Dynamic Vibrations of ‘Machine-Device-Tool-Detail’ in Condition of Thin Abrasive Grinding
It is presented the results of theoretic and experimental research of the problem of improvement quality of surface of the hole wear resistance slide bearing made from new high-alloy composite materials, which are sinthesized on the base of utilized and regenerated wastes production of parts from instrumental steel and nikel, type 11Р3АМ3Ф2, 7ХГ2ВМФ, 5ХВ3МФС, ХН55ВМТКЮ, ХН50ВТФКЮ the way of accounting dynamical vibrations of the system «machine-device-instrument-part» for conditions of thin abrasive grinding have been presented in the article. It was studied the schemes of enclosed dynamical system grinding machine, determine and calculated the transfer functions of cutting process of the abrasive instrument. Calculated the error forms of machining surface at thin abrasive grinding newest compozites with accounting action real parameters of cutting for condition stability system «machine-device-instrument-part». I was showen that dynamical vibrations system influence on the primary parameters of quality friction surfaces - the roughness Ra, degree of cool working K and his depth h. Develop the practice recomendations for industrial production.
