Abstract
PURPOSE:To freely control a finished surface shape by changing a mounting angle of a tip which provides a cutting edge forming a V-shape in the upper end edge part further a flank gradually tilting toward the bottom surface side in accordance with the flank being positioned from both end parts of the cutting edge toward its crossing point part. CONSTITUTION:A V-shaped cutting edge 2a is formed by a rake face 1a butt formed in a V-shape to the left and a V-shaped flank 1c in such a manner as to be directed to the side of a bottom surface 1b facing to the central part from the upper and bottom ends of an upper surface. While a cutting edge 2b is formed by a rake face 1d, butt formed in a V-shape to the right, and the flank 1c. Mounting this tip 1 to a broach main unit, a pin journal part is machined in a manner wherein a crossing point part of the cutting edges 2a, 2b is plunged into the central part of the pin journal part. Here the tip 1, when it is mounted on the broach main unit in a manner wherein the flank 1c gradually tilts, enables the pin journal part to be cut in the same diameter over the total length or in a larger diameter in accordance with the pin journal part in its position from the end part toward the central part.
