I need to have 1/8" ground off these two pieces of metal -

Is blanchard grinding or surface grinding the way to go? And why?
The look and texture of the resulting surface does not matter, and it will never be seen once back on the machine.
thanks, Mark

Wouldn't that amount of material removal be better suited to a milling machine than a grinder?

Like Ken said: a face mill would be more appropriate.

A milling machine! - thanks, I'll look for that service. Appreciate it.

Why do need/want so much material removed ?
Moderator
Yes, it’s definitely a milling job. Any typically equipped machine shop can do it. Is the opposite surface already machined?

Linear grinding or even planning might be the better choice if the opposing surfaces are moving parts.
What are you trying to accomplish? Those castings look like SCMI made them.
Contributor
Yeah, Italian parts for sure. Could be Griggio, too.
To the OP, do they really need to be re-ground? Could you just face-lap them with some emery paper or something?

I agree, re-machining these sorts of things should be a last resort. Parts will no longer be to spec one you get them back from the shop.

Yeah, but "why?"

Who knows? People need to realize they'll get better responses to questions if they would follow their own threads & respond to inquiries.

I checked in yesterday morning, got an appropriate answer, went to work, checking in now before I go to work.
Appreciate the knowledge available on here!

But you’ve still left out a piece of the puzzle.
You’ve tapped the wisdom here, but haven’t really done your part by adding to the discussion.

A shop with a shaper or a horizontal milling machine would be the fastest and probably cheapest way to go. Both those machines have been pretty much forgotten in a modern shop. If you find a shop with them they probably started before 1950.
