  • Patent number: 5154105
    Abstract: A pick off attachment for use with automatic multiple spindle machines includes a spindle and housing to be mounted within a sliding workholder, which is moveable along the longitudinal slide of the workstation of the cutting machine. The spindle is mounted upon a splined shaft which is mechanically linked to the spindle via a collet at one end and connected to the machine gear box at the other. The shaft extends partially into the spindle where it is connected to an ejector. The face of the ejector rests inside the shoulder of another collet. This collet is mounted on the interior of the spindle and serves to hold the part to be machined during the machining cycle. Two adjustable nuts on the shaft allow the positions of the part holding collet and the ejection mechanism with respect to the part to be machined to be varied.
