A crankshaft is mounted in a fixture (30) which rotates the crankshaft about its longitudinal axis and which tilts the crankshaft about a horizontal axis to allow machining of holes such as oil holes at various rotational positions and at various tilt angles to the longitudinal axis. Preferably, a cutting tool (36) moves along a horizontal plunging axis Z to machine holes on or offset from the longitudinal axis. Preferably, a pair of crankshafts are mounted side-by-side in the fixture to machine two crankshafts simultaneously. The fixture is mounted for tilting by trunnions (124). The pair of crankshafts are spun about the longitudinal axes by a motor carried on the tiltable fixture. An automatic tool changer and loading apparatus (34) store cutting tools and associated guide bushings for the cutting tools.

Un vilebrequin est monté dans un dispositif de serrage (30) qui le fait tourner autour de son axe longitudinal et l'incline autour d'un axe horizontal pour permettre l'usinage de trous tels que trous d'huile à différentes positions angulaires et à différents angles d'inclinaison. De préférence, un outil de coupe (36) se déplace le long d'un axe plongeant horizontal Z pour usiner des trous sur l'axe longitudinal ou en décalage par rapport à lui. De préférence, une paire de vilebrequins sont montés côte à côte dans le dispositif de serrage afin de permettre l'usinage des deux vilebrequins simultanément. Le dispositif de serrage est monté de telle sorte qu'il peut être incliné par des tourillons (124). Un moteur supporté par le dispositif de serrage inclinable imprime un mouvement de rotation autour des axes longitudinaux à la paire de vilebrequins. Un changeur d'outil automatique et un dispositif d'alimentation (34) stockent les outils de coupe et les douilles de guidage qui leur sont associées.
