MODERNIZATION OF THE 3B652 DRILL GRINDING MACHINE Smagin G.I ., Ph.D. (Engineering), Associate Professor, e-mail: dr.smagin@ngs.ru Yakovlev N.D. , Senior Lecturer, e-mail: n.yakovlev@ngs.ru Burdukov S.D. , Engineer, e-mail: sergej.burduckov@yandex.ru Bulanov P.A. , Master’s Degree student, e-mail: bulanov1992@mail.ru Kalugina N.V. , Master’s Degree student, e-mail: natas-kalugina@yandex.ru Orlova I.A. , Student Novosibirsk State Technical University, 20 Prospekt K. Marksa, Novosibirsk, 630073, Russian Federation Abstract The article represents the modernization variants of 3B652 drill grinding machine for opportunities to improve the accuracy of the clearance angle of sharpening drill tapered rear surfaces, as well as to simplify sharpening technology. In addition, the modernization of 3B652 drill sharpening machine provides the ability to disconnect motion scenes for the oscillations of the quill spindle which allows to implement sharpening of multi edge drills by the cross slide of the machine. Sharpening of multi edge drills is possible if the dressing spindle shaped grinding wheels are installed on the drill sharpening machine, according to the type of ruling devices used on universal grinding machines. Mounting these correcting devices requires the use of the mounting screw while drill adapter is attached to the plate by this screw to the cross slide. At the same time the case of drill adapter is removed from the machine during the setting of the shaped grinding wheel. Dial gauge (0.001) is also provided on the modernized machine capacity to control movement of the cross slide for sharpening drills.
