Those are zero-lead profiled cutters. You can use those on any mill (or lathe, in many cases) You can also use the rack-form cutter from those sets to generate teeth one-by-one on a CNC milling machine: https://youtu.be/SJQtx80euGM?t=172 (or, as shown in that video, a single-point tool) Or you can go the whole way and hob on your CNC mill, with spiral hobs. If you can set the work and spindle at the required angle. Vertical mill, poor video: https://youtu.be/ZhICrb0Tbn4 Horizontal mill, better video https://youtu.be/xdE46yvckbM Your ball-nose mill approach, though, is the only easy way I know of to make bevels, especially spiral bevels, without a specialised machine. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
