Abstract
An end mill includes a major-diameter shank, a cone-shaped connector portion disposed at the end of the shank, a minor-diameter body disposed by way of the connector portion coaxially therewith, a toothed element disposed at the leading end of the body, an installation recess dented slightly in the toothed element, and a cutting edge held in the installation recess so as to swell in the shape of an arc to protrude from an outer peripheral face of the body.
Claims5
A dimples processing method by milling, the dimples processing method being adapted for processing dimples, which are minor-diameter concaves or dents separated away from each other, by rotary cutting a surface of a workpiece using a milling cutter provided with one single toothed element which comprises one or two cutting edges disposed on an outer peripheral face near an end portion of a rod-shaped body having a rotational axis, the dimples processing method comprising:
- keeping a predetermined interval between the surface of the workpiece and the one single toothed element and moving the workpiece and the milling cutter relatively at a predetermined speed;
- providing the rod-shaped body of the milling cutter with a conical portion reducing diametrically as heading toward a leading end of the rod-shaped body, the one or two cutting edges being disposed on an outer peripheral surface of the conical portion;
- and
- forming the dimples separated away from neighboring dimples in a quantity of the number of cutting edges by rotating the rod-shaped body only once around the rotational axis.
