<p>PROBLEM TO BE SOLVED: To provide a simplified formation method for a rotating tool.SOLUTION: A rotating tool (2) has a basic body (12) extending in an axial direction (4); at least two chip grooves (14); a guide chamfer (22) connected to the chip grooves (14) in a rotational direction (24); a ridge (15) between the two chip grooves (14); a clearance (28) radially connected to the guide chamfer (22). In a first process step, the rotating tool (2) grinds an unprocessed rod (30) in a noncircular manner. In a second process step, the rotating tool (2) grinds to form the chip grooves (14) such that the guide chamfers (22) are formed at the positions with the maximum radius (R2) and the radius (R) is reduced subsequently to each guide chamfer (22) in order to form the radial clearance (28).</p> |
