Machinist's Bench Vises....why?

[1982fxr]

Were they less expensive because there was no anvil?

Some features they have that mechanic's vises don't? I mean, why weren't they all just mechanic's vises?

Mechanics vises are 30,000 psi and machinists vises are 60,000 psi and the machinists vises have always been more expensive.

Machinist is the top vise. They are the MOST expensive. They are built to much higher standards that a mechanics vise. Much stronger, heavier, better clamping action etc. The are not made to beat on, although they are seem to end up getting beat on.

Machinist vises are for use on machinery, like this:

I guess I should mention that the picture I posted is a joke, and that's not what a machinist vise is intended for. I figured someone would immediately point out the untruth I posted, and we'd all have a laugh.

I'm not sure if the use of the vise, or the use of the soup can is funnier.

Oh dear god that's a laugh!

A bench vise on a Moore jig borer with an endmill in a Wholhaupter UPA boring head and a ten pound soup can hammer!

I didn't think it was so funny. I've seen setups like that, only on junky cheap equipment using an asian import vise and a HF 4 lb. sledge hammer for fine adjustments. And I am not making this up!

Good info.. In never quite understood the difference either.

I'm surprised you hadn't seen it before. It was originally posted on PM.

A good machinist vise isn't going to be cheap. They are made to very high tolerances for surface squareness, flatness, parallelism and jaw flex. The one I typically use is rated at .0002 inches , plus or minus, variance. Striking a machinist vise with anything other than a dead blow hammer ought to be grounds for revoking a man card.

lametec,

I'm sure glad you followed that up with a disclaimer.
I almost fell off my chair when I saw that.

But that would work good for using your Z-feed to press in u-joints into driveline yokes . . .

Are you confusing a machine vise with a machinist vise? One mounts on a bench and the other mounts on a machine.

no neat sig line

Good catch.... my comments did indeed address the machinist vise.
