Zusammenfassung: | The method comprises introducing the parts to be machined into an assembly of working bodies, imparting to that assembly vibratory motions oriented essentially in a vertical plane and taking off the machining allowance with the working bodies in the circular motion of said assembly together with the parts. The machining is carried out preferably within a vertical layer of the assembly which is 100 to 300 mm thick, the assembly of the working bodies being oscillated at a frequency of 30 to 100 hertz and with an amplitude of 0.8 to 3.5 mm. The machining allowance is taken off as the parts are turned around by oncoming flows of the working bodies. The device comprises a base (3) on which are fixed, by means of an elastic suspension (4), a container (1) and a vibrator (2) connected to the container (1) in order to impart to the latter oscillations oriented in a vertical plane. The container (1) houses at least one partition (8) mounted at right angles to the plane of oscillations. The walls (9) and (10) of the container (1) and the partition (8) are oriented substantially in a vertical position and form a U-shaped chamber of the container (1) in a cross-section parallel to the plane of osciallations. The clearance between the partition (8) and the container (1) is not more than 300 mm but not less than 100 mm.
Le procede consiste a produire les pieces a usiner dans un ensemble de corps de travail, a donner a cet ensemble des mouvements vibratoires orientes sensiblement dans un plan vertical et a enlever la surepaisseur des usinages, les corps de travail ayant le mouvement circulaire de cet ensemble et des pieces. L'usinage s'effectue de preference dans une couche verticale de l'ensemble qui possede une epaisseur de 100 a 300 mm., l'ensemble des corps de travail oscillant avec une frequence de 30 a 100 herz et avec une amplitude de 0, 8 a 3, 5 mm. La surepaisseur d'usinage est enlevee lorsque les pieces sont tournees par des flux d'arrivee de corps de travail. Le dispositif comprend une base (3) sur laquelle sont fixes, a l'aide d'une suspension elastique (4), un conteneur (1) et un vibrateur (2) relie au conteneur (1) de maniere a donner a ce dernier des oscillations orientees dans un plan vertical. Le conteneur (1) comprend au moins une separation (8) montee a angle droit par rapport au plan d'oscillation. Les parois (9 et 10) du conteneur (1) et la separation (8) sont orientees essentiellement dans une position verticale et forment une chambre en forme de U |
