Help to identify this rotating table

[AJAXParticipant @ajax]

I'm not sure about this. It came with a milling machine I purchased recently but may have nothing to do with it. There appears to be no mechanism to lock rotation but I would welcome your correction.

Can you help with identification or suggest a use?

Many thanks,

Brian

Maybe set to the desired angle and secured in position via whatever was fitted to it?

No ideas apart from that initial thought.

Looks like a vice base, a very specific vice that fits between the two raised edges on the ground surface.

Likely to be a cutter grinder vice base.

That seems quite possible. Thanks

The two studs may have the dual purpose of holding whatever was intended to sit on it and locking the rotation. Take it apart and all will be revealed.

That looks to be good quality.

Upon dismantling the base it's quite clear the two studs do lock off rotation. If I'd looked more carefully I would have noticed the studs were partially threaded and the nuts were at their limit (thus not locking off). But adding some drilled flat across the studs I can confirm it locks solid.

Quite right – should have done that first! But I'm still none the wiser as to what it's from. The 90 degree scale should narrow things down, I guess.

I think so.

And it was well looked after with a thick layer of grease (and so presumably was not being used on a grinder).
