    摘要: A pair of opposed spindleheads are rigidly mounted on a bed for holding a crankshaft to be machined between a pair of chucks on the ends of indexing spindles. One or more, preferably two, cutter assemblies are provided between the spindleheads for movement therebetween. Each cutter assembly includes a carriage slidable along a guideway on the bed and itself having slidably mounted thereon a slide which is reciprocable in a direction normal to the axis of the crankshaft. Mounted to the slide for rotation about an axis parallel to the axis of the crankshaft is a disklike tool holder carrying a annular, rotary cutting tool in an eccentric position thereon. The cutting tool has an annular row of internal cutting edges surrounding with clearance a desired part of the crankshaft to be machined. As the cutting tool is revolved at a constant speed, the desired crankshaft part is thereby machined with the concurrent bidirectional rotation of the tool holder relative to the slide and linear, bidirectional travel of the slide relative to the carriage. The machining operation is controlled numerically.
