Title (DE) VERFAHREN ZUR BEARBEITUNG DER OBERFLÄCHE VON PLANKOMMUTATOREN
(EN) PROCESS FOR MACHINING THE SURFACES OF PLANE COMMUTATORS
(FR) PROCEDE D'USINAGE DE SURFACE POUR COLLECTEURS PLATS
Abstract:
(DE) Es wird ein Verfahren zur Bearbeitung der Oberfläche von Plankommutatoren vorgeschlagen, das sich dadurch auszeichnet, daß der Plankommutator (1) in Rotation um seine Längsachse (3) versetzt wird, daß dessen Oberfläche mit Hilfe eines als Topfscheibe (5) ausgebildeten Schleifkörpers bearbeitet wird, der um eine Achse (7) rotiert, die mit der Längsachse (3) des Plankommutators (1) einen Winkel von vorzugsweise 5° bis 10° einschließt, daß der Schleifkörper und/oder der Plankommutator dabei eine Translationsbewegung senkrecht zur Drehachse (3) des Plankommutators (1) ausführt und daß sich der Schleifkörper und/oder der Kommutator parallel zur Achse 3 bewegt, um die Zustellung durchzuführen.
(EN) In the process of the invention, the commutator (1) is first set in rotational motion about its longitudinal axis (3). Its surface is then machined with an abrasive body in the form of a cup wheel (5) rotating about an axis (7) which makes an angle of preferably 5° to 10° with the longitudinal axis (3) of the commutator (1). At the same time, the abrasive body and/or commutator is made to execute a translational motion perpendicular to the axis of rotation (3) of the commutator (1), and the abrasive body and/or the commutator is moved parallel to axis 3 in order to advance one relative to the other.
(FR) Procédé d'usinage de surface pour des collecteurs plats, caractérisé par le fait que le collecteur plat (1) se déplace en rotation autour de son axe longitudinal (3), que sa surface est usinée à l'aide d'une meule formée en coupelle (5) tournant autour d'un axe (7) formant un angle de préférence de 5° à 10° avec l'axe longitudinal (3) du collecteur plat (1), que la meule et/ou le collecteur plat exécutent un mouvement de translation verticalement à l'axe de rotation (3) du collecteur plat (1) et que la meule et/ou le collecteur sont mobiles parallèlement à l'axe 3 pour effectuer le mouvement d'avance.
