The elastic base grinding-wheel for the smoothing and polishing of toroidal contours of hard materials comprises a rigid-material support body, which may also be divided into two parts (1A, 1B) along an equatorial plane in a substantially centered position, has an internal shape (2, 3) suitable for mating operatively with the motor shaft with which it is coupled, and an external (4) shape congruent with that of the contour of the material to be smoothed and/or polished. At least a wing (5, 6) at one and/or the other end of the support body (1), is arranged for receiving and holding a coating (12) of elastomeric material injected or vulcanized in situ. The part (13) of the injected coating (12) of elastomeric material directed towards the workpiece is coated with elements (14) of relatively flexible abrasive material, so that the overall contour corresponds to the final shape that must have the workpiece after the smoothing and/or polishing.
Une meule à base souple pour le ponçage et le polissage de matériaux durs comporte un corps de support en matériau rigide qui peut être divisé en deux parties (1A, 1B) le long d'un plan équatorial en position pratiquement centrée, et présente une forme intérieure (2, 3) conçue pour s'adapter à l'axe du moteur avec lequel il est accouplé, ainsi qu'une forme extérieure (4) coïncidant avec le contour du matériau à poncer et/ou polir, Au moins une aile (5, 6) située à une des extrémités du corps de support (1) est conçue pour recevoir une couche (12) de matière élastomère injectée ou vulcanisée in situ. La partie (13) du revêtement injecté (12) en matière élastomère dirigée vers la pièce à usiner est recouverte d'éléments (14) en matière abrasive relativement flexible de sorte que les contours généraux correspondent à la forme finale de la pièce à usiner après ponçage ou polissage.
