Leave the vise on the mill table with coolant under it?

When I dial one of the my mill vises, make some cuts, vacuum off the chips and coolant mixture, I leave it that way.

My brother takes his vises off, wipes down the table, and leaves the mill with no vise. He claims the coolant causes rust under the vise.

When I take off a vise, there is some discoloration, but it comes right off with a fine stone. I think I could repeat this for years before I picked up .001" out of flat on the table. I like having the mill ready to go.

But that is all seat of the pants for both of us.

Is there some definitive knowledge?

I rub my iron with a block of sealing wax before mounting a vise.

I would suggest a Scotch-Brite pad and a little WD-40 for cleaning the surface rust off, rather than a stone. Then dissolve some wax (as in from a wax stick) in some kerosene and wipe the table down with that. It should pretty well fix the rust problem. (There are, of course, other things that work well, too.)

Wouldn't Astroglide be slipperier?

"Sealing wax" ??? That hard red stuff that has to be melted and driped on a document and then impressed with a fancy ring. ???? ...lew...

When moving machinery I've seen hundreds of "under-vise" rust patterns on milling machines, mostly (and the worst) on production mills.

I spritz a little LPS 1 before placing the vise. Also, I use a coolant with a great rust inhibitor, from Engineered Lubricants. They mixed up something special just for my mix of materials and processes. I wouldn't get too hysterical about some slight discoloration.

Im curious..when you mount a vise..exactly WHERE do you put it?

And does the Missus know you been fooling around in the shop?

Give the table a smear of way oil before bolting down the vise.

The culprit is not rust but electrolysis. This is caused by acids in the coolant. The dis similiar metals will eventually cause the less noble metal to turn black. This will happen even with stainless steel unless it has been passivated. The ph of the coolant should be monitored.

Don't you like the visual? (Now, just TRY to get it out of your head!)

I tried the extra oil trick and only got more black discoloration. Then I read that anerobic bacteria are the main culprit in the coolant making the black stain under the vise. Adding more oil only gives the bacteria more food. After reading about the bacteria it made perfect sense. ERS

That might suggest the use of a silicone based oil, give the little buggers something they can't eat :-)

I've pulled vises off mills that have been mounted for ages. Table is fine underneath. We use waterbased aka toilet water coolant.

I suppose a guy could rub some paste wax on for protection like most woodworkers do to protect their saws and jointers. If any slight marking offends you, I'd use scotchbrite vs a stone.

But a cast iron vise base sitting on a cast iron mill table dosent pose much of a "dis similiar metal" pair does it?????? ...lew...
