Loader and unloader mechanism (10) for a machine tool having a workpart-holding spindle (14) wherein a workpart load tube (32) and unload tube (34) and associated workpart loading fluid cylinders (40, 42) are arranged relative to a tool-carrying turret (20) in a manner that workparts (W) are fed to the spindle (14) through the load tube (32) and removed from the spindle after machining to a workpart holder (33) on the tool-carrying turret (20), which then positions the workpart holder between an unloading tube (34) and a workpart unloading fluid cylinder (76) where the workpart is ejected from the workpart holder into the unload tube.
