Carbide ballnose sharpening

It's obvious is mm Min. How can it be 117 meters a min? The fastest rapids out there are in the region of 60 mtrs a min. Even if it was inches it would be nearly 3 mtrs a min, Its obvious its not that speed for a 2 mm ball mill in stainless


For a start you have to remember speed and feeds calculators are a guide, often a very general guide you have to throw away. These speeds and feed will be optimum for optimum cutting conditions on a proper machine.

The problem he has is the machine. It's a very weak machine not deigned for cutting metals. You will be getting tons of deflection, if you deflect you do not cut, if you deflect you rub, if you rub you generate tons of heat compounded the fact you are working in stainless. A bad combination that will always be problematic.

Carbide needs to be worked and made to cut. If you don't have a machine with the rigidity to do this you will always be fighting a battle.
