I've just gotten a Baldor 7 inch grinder, 3600rpm, half horsepower. It had silicon carbide wheels on it, but ill be using this grinder exclusively for gridning high speed tools.
The only suitable wheels I can get that are designated to be for bench grinders are, CGW blue aluminum oxide, appare rlt designed to grind high speed steel. Id get 36 grit and 80 grinder, but the hardness for both is K.
From what I understand, K hardness is a bit hard for hand grinding, and I'd be looking for something in the I or J range.
If I look in the wheels for surface grinding, at a semi local shop, I have a mich higher selection of 7 inch wheels, but they have 1.5inch arbor holes.
I can make an adapter no problem, but can I use a surface grinding wheel on the bench grinder?
The grinder asks for 1 inch wide wheels, but typically the 1 inch wide surface grinding wheels have a recess on one side.
Will any of these features make it unsafe to operate the surface grinding wheel in a bench grinder, given that I make an appropriate bore adapter and it is run below the rate rpm?
I could imagine that the recession could be an issue, as when I grind hss, ill be using not the entire endface of the wheel simultaneously like in surface grinding, but I will be using either side of the wheels face, depending on what feature I am gridning into a peice of hss.
Thank you for reading and looking forward to the replies.
