Head Kryivoruchko P., Registration Date 18-03-2004 Organization The open joint stock company " The Ukrainian research institute of refractories named A.S.Berezhnoy" popup.description2 The research object - process of precision diamond treatment of products with elements of spherical surface from corundum ceramics.The work purpose - ascertainment of a precision treatment possibility of parts with elements of spherical surface and the manufacture of trial lots of mechanically treated parts from corundum ceramics of different configuration in the institute conditions.The research method - investigations of a precision mechanical treatment of spherical surface were conducted on a special rigging for grinding and operational development of spherical surface.Analysis of literature sources was carried out as well as a technical assignment for the device for grinding products with elements of spherical surface and working drawings of a gadget were worked out.The possibility of a precision treatment of parts with elements of a spherical surface in the institute conditions was ascertained as well as diamond instrument was worked out. Technological parameters of grinding and operational development of products with spherical surface from corundum ceramics were optimized and and trial lots of a spherical head of endoprosthesis of the hip joint were produced. Trial lots of corundum parts for the scientific production department "Технобим", city Kiev; Troitsky institute of innovative and thermonuclear research, city Moscow; production department "Комунар",city Kharkov were produced. The work should be continued for the purpose of researching a mechanical treatment processes of corundum ceramics and the manufacture of trial lots at requests of industrial works.
