Title:
FORM ROLLING TOOL FOR SPLINE MACHINING AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2008006443
Kind Code:
A
Abstract:

To provide a form rolling tool for spline machining and a manufacturing method therefor, wherein the strength of machining teeth is secured and the durability can be improved and the tool can be manufactured at a low cost.

A bristle brush is parallel-shifted in the direction of an arrow L while rotating, and as a result, the chamfering is applied to the machining teeth 12 with abrasive grain adhered to the bristle of the bristle brush so as to form chamfered face parts 40 at the peripheral edge parts of the scrape-off face parts 30 of the form rolling tool. Since the large number of machining teeth 12 can be continuously chamfered at a time and a working time can be remarkably reduced, so that the form rolling tool for spline machining can be manufactured at a low cost. Further, the chamfered face parts 40 are formed at the periphery edge parts of the scrape-off face parts 30, so that the durability of the form rolling tool can be increased by suppressing the machining teeth 12 from being damaged with chipping, etc.
