Title:
METHOD OF MANUFACTURING FILING WHEEL
Document Type and Number:
Japanese Patent JPS52148367
Kind Code:
A
Abstract:
This method is particularly suited for practice on a multiple spindle screw machine in which each work spindle carries a length of bar stock. The work end of each bar is formed, sized and drilled in a conventional manner to form thereon a wheel shaped workpiece which is then rotated between two thread dies to form diagonal grooves in its periphery. The work is then subjected to two successive broaching operations which cut grooves transversely of the lands formed by the threading dies. When the work has entered the bore of the second broaching tool, the tool is rotated slightly relative to the work to upset the teeth so that their sharp cutting edges are caused to face outwardly.
