Abstract
Headstock and tailstock chucking apparatus for crankshaft machine tools, such as lathes and grinders, utilizing a centering hole defined in the crankshaft workpiece end for axially locating the workpiece relative to the machine, and the machining tools. The stock spindle chucks utilize a center engaging a previously located and dimensioned workpiece center to axially position the workpiece, which is biased into firm engagement with the center prior to chucking. The chuck center and workpiece is axially located and spindle motors reciprocate chuck actuating mechanism sequentially producing axial locking and radial chucking of the workpiece. Further, automatic limit switch positioning apparatus is employed to automatically position machine limit switch controls in accordance with workpiece dimensions and quill location.
