I'm thinking of getting a double-sided cast iron griddle like this:

iron surface, whereas a machined surface is generally considered
better.

Is this something that a machine shop in the UK could do easily &
perhaps cheaply? What exactly would I ask when phoning up --- "can
you just mill the cast surface off an iron griddle?" or something like
that?

Thanks.

Often the problem is holding the item in such a way as to holding firmly
whilst not fouling the cutter path and secondly those sort of items are
rarely flat.
All in all a PITA and the charge of even an hours work (jigging,set up
and machining time) send customers away.

I really try and avoid those "can you just" jobs like the plague even
for friends and family to be honest.

You might have a fighting chance to do some smoothing on these just with
normal abrasives on a random orbit sander - working up through the grades
as one would on wood, rather than attempting to mill it in the normal
metalwork sense. All that is really required is smooth rather than truly flat.


Um, not if you're planning on using it on an Aga or similar. In this case
flatness is way more important than smoothness.

Depends on what the OP is intending using it on.
