Feed fingers are used as collets for supplying a workpiece of NC lathe and multi spindle lathe with auto bar feeder.

These are called “pusher” since these are collets which push in bar material.

Feed collets hold a workpiece only by the spring force of the collet itself. Therefore, cautions are needed for clamping heavy workpiece.

The whole equipment will be cheap, since the opening-and-closing mechanism of collets are unnecessary.
