A grinding machine is a tool or piece of equipment used for removing material from a workpiece via abrasion. They typically employ rotating abrasive wheels to shape, smooth, or finish workpieces through grinding. The machining process uses abrasive particles to remove material from a workpiece's surface.Web

So I did eventually manage to hard mill a blade. Was not fun. Ruined the blade due to the bow it introduced....$60 in endmills....no more hard milling...lol. I did what I call "pattern machined". I did this to lessen the finish grinding.By leaving "valleys" there is much less material that need to be removed to get to sharp.Web
