I am looking for any information on a i.d grinder that can swing at least 75 degrees. I have a van norman no. 25 radius grinder that we use now, however it is getting wore out and cant take out of production to get it rebuilt. I would love to find another one.... good luck to me!!! cant even find info on the early 1900 machine. I have some parts that require a 15 degree angle off the face so 75 degree from the i.d anyone have any info of a machine out there capable of this?

Sounds like a perfect job for an Arter or Heald rotary surface grinder. The rotary chuck on those can be tipped to grind tapered faces.

Or a universal toolroom/tool and cutter grinder, where you can swing both the wheelhead and the workhead around ? Arters and Healds are not so easy to find these days

Heald 273a will swivel all the way to 90 degrees I am almost certain. I sold mine or I would check. Best ID grinder out there for tool room type work

There's a decent-looking 72A3 up in Maine someone here posted with the cross-sliding head but that much angle is a lot of swing. The part better not be very long or he'll run out of room .... worth a look though. Probably real cheap, it was at a scrap yard.
Pretty sure you're right, they do go 90 ... (jealous of your 273. Nice.)

For a little followup, happened across an Arter rotary surface writeup, they go to 10* off vertical. So no love there.
