Abstract
Abstract A system for the machining of work pieces, particularly the abrading of die rolls for a tube reducing mill, where the work piece and the master pattern or cam are mounted for rotation on a common shaft and moved relative to a master follower and rotating tool, respectively, with this relative movement being biased translation with only the angle of the translation varying with respect to the axis of rotation for causing the follower to traverse the entire control surface of the master and correspondingly cause the tool to duplicate the master control surface in the work piece. The follower and tool are mounted on a common table, which table is mounted with respect to a base for only translation, that is, the table will not rotate with respect to the separately mounted master and work piece. A slide mechanism allowing only translation of the table is rotated independently of the table to traverse the direction of table translation through an angle of 180*. Elements are provided to bias the table in the direction of translation so that with the 180* rotation of the slide, the follower will traverse the entire control surface of the master, in one plane. The master is rotated about an axis parallel above-mentioned the abovementioned plane so that its entire three dimensional surface will be engaged by the follower.
