This invention relates to machine tools. It has among its objects to provide an improved machine tool of the so-called two-at-a time type described and claimed in the Kelly Patent No, 2,201,182, patented May 21, 1940, whereby it is made possible to extend the use of such machines to those uses, such, for example, as the making of roller bearings, wherein it is important for the pieces to be free from the burrs produced by the breaking off of the same during cutting and before completion of the cutting off operation. A further object of this invention is to provide such an improved machine wherein the pieces during the cutting off operation are grasped at their extremities by work rotating means rotating synchronously with the work spindles, so that these pieces-are severed cleanly from the stock by the cutting off tools, and subsequently withdrawn and ejected, all through improved mechanism cooperating in the desired sequence with the remainder of the mechanism of such a machine. A still further object of this invention is to provide an improved attachment for such machines whereby the same may be adapted to such work and in process of ejection after the cutting off operation and as they approach piece ejecting position. |
