Re: Need advice on a Grinder
Where did you get that formula? The formula on the buffing & polishing booklet says....1/4xDia. of wheelxrpm.That would give me 6900 sfpm. on an 8" wheel. And 5250 on a 12" wheel.But it is certain that which ever formula is used, the 12" wheel is going to spin slower.Am I still going to benefit using the bigger grinder at slower speeds, but being able to put more pressure on the part, & making more heat?
