APPARATUS FOR MACHINING WORKPIECES AND METHOD THEREFOR

摘要

During operation of an apparatus to machine a workpiece, an unfinished workpiece is gripped by a workpiece loader and unloader assembly at a conveyor station. The loader and unloader assembly moves the workpiece along the axis of a spindle assembly through an opening in a shield which minimizes the accumulation of material cut from a workpiece on the loader and unloader assembly and on a conveyor assembly. The loader and unloader assembly moves a finished workpiece from the spindle assembly, rotates a support arm through a distance which is less than 90 DEG to the condition of an unfinished workpiece in alignment with the spindle assembly and inserts the unfinished work-piece into the spindle assembly. The workpiece loader and unloader assembly then comes back through the opening in the shield and transfers the finished workpiece to an outfeed section of the conveyor assembly.
