Method, tool and device for profiling a finishing tool

A method for profiling a finishing tool (2), in particular a grinding worm, having a first and a second flank (4, 5);

• the method comprising the steps of:
• arranging a cutting portion (30;
• 31;
• 130A;
• 131A) of a profiling tool (9;
• 109) in contact with the first flank (4);
• causing the cutting portion (30;
• 31;
• 130A, 131A) to slide in contact with the first flank (4) so as to profile it;
• removing the cutting portion (30;
• 31;
• 130A, 131A) from the first flank (4);
• automatically rotating the profiling tool (9;
• 109) so as to arrange the cutting portion (30;
• 31;
• 130A, 131A) in contact with the second flank (5);
• causing the cutting portion (30;
• 31;
• 130A, 131A) to slide in contact with the second flank (5) so as to profile it;
• and,
• wherein the profiling tool (9;
• 109) is a disc rotatable around a first axis (L);
• wherein the step of automatically rotating the profiling tool (9;
• 109) provides for the rotation of the profiling tool (9;
• 109) by at least 180° around a second axis (N) transverse to the first axis (L).
