grinding on a mill

[Black_Moons]

Agreed, Grinding on the mill or lathe of hard surfaces is a great idea.

Trying to hold surface grinder tollerances, Is not. But the two things are totaly seperate.

You might of just hardened something, And only need to grind it within 0.001" after hardening distorted it. Or the grinding might just be to remove scratchs and other defects from a surface that is too hard to mill, but again does not need absolute precision.

Would it be reasonable to think that you could fab up something to allow grinding small surfaces like tools or the edges of parallels?

I'm not sure how you'd correctly align the work...

i have never done it in the mill. but have used my tool post grinder on my shaper.

Nope. What makes grinding machines different is the precision in the ways and slides. If you have Bridgeport quality ways you have Bridgeport precision regardless of what is in the spindle. If you just want it to look like it was ground then you might fool someone. Only until he checked flatness, etc.

Nope. As has been said, there are tons of different grinding operations of which only some need a (more) precision machine other than a mill or a lathe (or a shaper). I've ground in a lathe some axles for bearing fits, some just for decoration, and used a diamond cup wheel in a CNC milling machine to grind some shapes to an SNMG lathe carbide bit.

So yes, it can be done, if your needs are sharpening your tools or making angles or something easy like that and you don't have some a dedicated machine for such an operation.
