Abstract
A spline rolling tool including a plurality of forming teeth that are to bite into a cylindrical workpiece so as to roll splines in the workpiece. Each of the forming teeth has an incomplete toothed region in which a crest of each forming tooth is removed such that an upper end of each forming tooth in the incomplete toothed region is defined by an incomplete-toothed region surface that includes a curved surface portion, a flat surface portion and a slant surface portion. The incomplete-toothed region surface is defined at its periphery by a chamfered edge that has a surface roughness of not larger than about 3.2 μm. Also disclosed is a process of manufacturing the spline rolling tool, which includes a chamfering step of forming the chamfered edge by using a wire brush having abrasive grains that are fixed to bristles of the wire brush.
