Abstract
PURPOSE: To machine the parts of journals of a crankshaft with high precision and high efficiency by providing a individual steady rest device supporting worked and unworked parts of journals on both sides adjacent to the part of journal to be machined.
CONSTITUTION: Journal parts J1WJ7 on a crankshaft W are worked 30 sequentially in accordance with their arrangement order, while unworked journal parts adjacent to the journal part to be worked are supported rotatably by steady rest devices 51 and 83 supported by plural number of holding arms, the center of shaft of the unworked journal part not being displaced. By the fact that the journal parts and chucks 17 and 18 are supported by the steady rest devices 51 and 83, the deflection of the crankshaft is prevented, thus a precise machining can be performed.
