Abstract
A method and apparatus for making rotary die racks having an elongated shape including a partially circular forming face of less than 180.degree. and a flat mounting surface that faces in the opposite direction as the forming face. Cast metal blanks of the die racks are secured to a rotatable spindle in a side-by-side relationship to turn the forming faces. Forming projections, i.e. teeth that extend parallel to the axis of the forming face, are then cut in the turned face. Heat treating of the die racks is then performed before mounting thereof on a fixture to perform a finish grinding of the teeth. The spindle preferably includes a spindle member and a central shaft on which the spindle member is mounted for rotation. The fixture includes a pair of spaced end plates and a bed that extends between the end plates and has a stop and an adjustable positioner for clamping the die racks.
