AbstractA spindle assembly for a metal working lathe includes a generally cylindrical spindle body having a forward end and a rearward end and an internal bore extending longitudinally thereof. An arbor having a forward end connectable to a workpiece is insertable into the bore of the spindle body and has a rearward end provided with a first annular tapered surface. A second annular tapered surface is formed on the arbor at an intermediate position between the forward and rearward ends thereof. The forward end of the spindle body is formed with an interior annular tapered surface configured to seat against the second annular tapered surface of the arbor. A collar member is slidingly insertable within the bore of the spindle body and is formed with an interior annular tapered surface. Means are provided for biasing the collar member into engagement with the arbor when the arbor is drawn interiorly of the spindle by a draw bar, whereupon the first annular tapered surface of the arbor seats against the interior annular tapered surface of the collar and the second annular tapered surface of the arbor seats against the interior annular tapered surface of the spindle body.
