ABSTRACT:
A method and apparatus for grinding work pieces having internal chambers comprising loading blank work pieces onto respective ones of a plurality of mandrels provided on a rotatable member which member is rotatable about an axis of rotation extending parallel to the mandrels, the mandrels being equi-spaced about the axis of rotation; rotating the blanks on the mandrels; rotating a profiled grinding wheel; effecting rotary indexing of the rotatable member such that each of the blanks thereon successively moves relatively rapidly from a position spaced from the grinding wheel toward the grinding wheel to a position immediately adjacent the grinding wheel, moves relatively slowly from the adjacent position into contact with the grinding wheel and stops at the contact position for grinding to be completed, then moves rapidly away from the grinding wheel; and ejecting the ground work piece from the mandrel. Means are also provided for forming a through-passage axially in the work pieces.
