摘要： A form rolling tool for spline machining enabling an increase in durability by securing the strength of machining teeth and manufacturable at low cost and a method of manufacturing the form rolling tool. In the method, a bristle brush is translated in the direction of an arrow L while rotating to apply chamfering to the machining teeth (12) by abrasive grains adhered to the bristles of the bristle brush so as to form chambered 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, the form rolling tool for spline machining can be manufactured at low cost. Also, the chamfered face parts (40) are formed at the peripheral edge parts of the scrape-off face parts (30), the durability of the form rolling tool can be increased by suppressing a damage to the machining teeth (12) by chipping.
