I've been wanting to upgrade my surface grinding capabilities and since I won't be getting a new machine! I guess that means working with the one I have.
It's an ABA manual machine made in 1942 and still in good shape but does not have a coolant system. (Maybe I need to install one?) Right now I manualy spray water whille grinding.
I use the grinder for finish surface grinding hardened knife blades usually made from highly alloyed carbon or stainless steels. Hardness is typically around HRC 58 - 61.
Once in a while I would like to be able to surface grind annealed steel stock also.
I have a bunch of corund wheels however I mostly only use a white, medium grained stone.
A dealer has suggested what I need is a CBN wheel for the machine. Those are pretty darn expensive. Dealer says I can grind dry with the CBN wheel. Is that so?
Also I would only be able to do the hardened steel with CBN and would still need corund wheels for anything else. Since I only have one flange set for the machine, I would have to draw the flange and have new ones made too ... more expenses.
Do you guys think the CBN setu would be worth it for me? Or should I perhaps try another sort of stone wheel? I've heard the "green ones" are good??
Any thoughts or tips would be appreciated!
