CA 2596981

The invention relates to a device (50) for green machining bevel gears, comprising an CNC machining station (60) for gear cutting a wheel blank (K2). The machining station (60) comprises a tool spindle (61) which is used to receive a gear cutting tool (62) and a work piece spindle (33; 63) which is used to receive the wheel blank (K2). Said machining station (60) also relates to a machining station which operates in a vertical manner. Said device (50) also comprises a vertically processing station (70) which comprises a tool holder (73) and a work piece spindle (72) which is used to receive a work piece blank (K1). Said machining station (60) mechanically forms a functional unit together with the pre-machining station (40; 70), wherein the work piece blank (K1) undergoes green machining in the pre-machining station (70), in order to transfer to the first machining station (60) after the first green machining as a wheel blank (K2) and then it is to be cut. Said machining station (60) and the pre-machining station (70) are linked together in terms of data and control.

L'invention concerne un dispositif (50) d'usinage avant traitement de roues coniques, ce dispositif comprenant un poste d'usinage CNC (60) pour endenter une ébauche de roue (K2). Ce poste d'usinage (60), qui est un poste de travail vertical, est équipé d'une broche pour outil (61) pour recevoir un outil d'endentement (62) et d'une broche pour pièce d'usinage (33; 63) pour recevoir l'ébauche de roue (K2). Le dispositif (50) comporte en outre un poste de pré-usinage (70), également vertical, comportant un porte-outil (73) et une broche pour pièce d'usinage (72) pour recevoir l'ébauche d'une pièce d'usinage (K1). Le poste d'usinage (60) constitue avec le poste de pré-usinage (40; 70) une unité fonctionnelle mécanique où l'ébauche d'une pièce d'usinage (K1) est soumise, sur le poste de pré-usinage (70), à un premier usinage avant traitement, pour passer ensuite en tant qu'ébauche de roue (K2) sur le poste d'usinage (60) pour l'endentement. Le poste d'usinage (60) et le poste de pré-usinage (70) sont interconnectés par des appareils de commande.
