摘要：
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.
摘要（中）：
曲轴安装在固定装置（30）中，该固定装置使曲轴围绕其纵向轴线旋转，并且使曲轴围绕水平轴线倾斜，以允许在各个旋转位置和与纵向轴线以各种倾斜角度加工诸如油孔的孔。 优选地，切割工具（36）沿着水平插入轴线Z移动以在纵向轴线上偏移或偏离纵向轴线。 优选地，一对曲轴并排安装在固定装置中以同时加工两个曲轴。 固定装置安装成用耳轴（124）倾斜。 一对曲轴通过承载在可倾斜固定装置上的马达围绕纵向轴线旋转。 自动换刀和装载装置（34）存储用于切割工具的切割工具和相关联的导向衬套。
