摘要 |
A feed device in the form of a feed finger for advancing a workpiece bar through a collet. The feed finger comprises a gripping sleeve with an internal bore in which the workpiece can be frictionally gripped. The sleeve is split into several segments each of which can be displaced radially-inwardly while remaining parallel to itself whereby to vary the effective cross-sectional size of the bore to enable the bore to receive workpieces of any cross-sectional size with a predetermined range. |
