Hey guys,
I need some help on getting the right wheel.
I’m a little out of my league with grinding. I’m trying to re-sharpen some knife blades. They are 4” long, 3/4 high, 1/8” thick with a 40° knife edge.
The material is high speed steel. Not sure of the grade but the grinding wheel I’m using isn’t cutting at all. And it’s getting the blade smoking hot.
The Wheel I'm using is a Norton general purpose Toolroom grinding wheel. 7 inch aluminum oxide 100 grit grade I. McMaster number 4397A68
I have to cut it dry because I’m using a POS end mill grinding machine.
I appreciate a little advice.
