Choosing a grinding wheel
Choosing a grinding wheel
(OP)
We are looking at replacing a recip surface grinder. It is used to grind heat treated 1566 (~50 rc) and m2 (~60 rc) steels. currently we use an al oxide wheel that does very well on the 1566 but has a little trouble maintaining flatness on the m2.
Main decision: wheel type. CBN has been suggested by the wheel manufaturers but the machine manufacturers seem worried about it for the 1566 in recip. we use cbn to creep grind these same parts with no problem. other suggestions?
also, what would be the benefits of changing to creep feed? flatness of the thin section (0.050-0.150") is the most important, surface finish, not so much.

RE: Choosing a grinding wheel
these look like a very useful primer on cooling and I will read as much as i can.
I think i will be limited to a water-based cooling system so i don't have to add a parts washer to the cell. (space constraints and cycle time)
should this narrow my available choices?

glad to be of help
RE: Choosing a grinding wheel
Current: vertical spindle, aluminum oxide ring wheel, recip,
water based coolant
benefits of changing to:
horizontal spindle? other than surface finish.
CBN? the cost is hard to justify, are there any other options out there?
creep feed? is speed the only reason to change?

The nuts and bolts of this kind of change require a lot of study and discussion. It is about selecting the best alternative for you in your specific situation - in the manufacturing world there is no one right answer but rathar a whole lot of answers that will all get you to the same place and it is your/our job as maufacturing engineers to select among them.
