Apparatus for machining a desired profile in a continuous mixer agitator and the like includes an attachment for a vertical boring mill or lathe and the like, wherein the attachment comprises a base plate with mounting structure to secure the base plate on the table of the boring mill or face plate of the lathe, and a rotary indexing table is carried by the base plate in an offset position relative to the center of the table or face plate and the like, said indexing table rotatably supporting the agitator on the base plate and the base plate rotatably supporting the indexing table, such that by properly adjusting the offset and speed of rotation of the indexing table, a desired profile is automatically machined in the agitator. The method of machining continuous mixer agitators includes the steps of determining the profile desired in the agitator, determining at least one radius of curvature necessary to generate an arc to obtain the desired profile, determining the center for the radius of curvature, and wherein the center corresponds to the center of a lathe or vertical boring mill and the like and then positioning the agitator to be machined with its center a distance from the center of the lathe or vertical boring mill and the like an amount necessary to obtain the offset to accomplish machining of the desired profile on the agitator as the agitator is orbitally rotated about the center.
A turning machine for machining a desired profile into a workpiece, said machine including a rotatable member rotatable about a first axis, and to which a workpiece is normally secured for rotation of the workpiece about said axis;
The method of machining a desired profile into a self-wiping, corotating, continuous mixer agitator, having opposite, convex, curved flanks, and opposite crests, comprising the steps of determining the size of the crests desired and determining the radius of curvature desired for the flanks, measuring the offset of the center for the radius of curvature of the flanks from the center of the agitator, providing an attachment for a vertical boring mill or lathe and the like, wherein the attachment includes a rotary indexing table, supporting the agitator to be machined on the rotary indexing table, positioning the center of the rotary indexing table a distance from the center of the vertical boring mill or lathe and the like a distance equal to the aforesaid offset, setting the rotary indexing table to a predetermined first setting to machine at least one flank of the agitator, and energizing the vertical boring mill or lathe and the like and substantially simultaneously therewith energizing the rotary indexing table to effect rotation of the rotary indexing table about its axis and also to effect rotation of the vertical boring mill or lathe and the like to thus obtain orbital motion of the agitator and movement of the agitator relative to a cutting tool to machine at least one flank of the desired profile therein.
