Arter rotary surface grinder - or something

"Oh, you want a 12" Arter!" What other brand will do this? I only need to
do 2 to 6 a week but the guy that does them for me is slow and expensive.
So, if you want to unload that grinder in the back... I know I've posted
about this job a hundred times but haven't fell into the right situation. I
DID come up with some truly stupid ideals all by myself! I just need some
Unobtainium and some Disapearium and that Escher CAD program

Assuming the bevel you desire to grind is a shallow cone, for lack of better description, the Arter is the grinder of choice, for others don't provide the proper motion. I've never run an Arter, so make sure that it has the capability of grinding the angle desired. For the most part, surface grinders are intended to grind parallel to the table motion. It's possible the Arter has the ability to feed the head at an angle. Dunno.
The difference between an Arter and a Blanchard is the way the wheel sees the work. Blanchard wheels parallel the table, Arters see the table with the periphery of the wheel (at right angles to the table). In both cases the table spins.
If you find the Arter will not suite your needs, the typical universal cylindrical grinder would do the job as long as it has the required swing. That may be how the shop is doing them now. Setup is labor intensive because the part is likely held in a chuck and dialed in. Much slower than simply placing it on a magnetic chuck, certainly.

Tom, A quick check of an old book I have discusses rotary grinders that have tilting heads, or tilting tables. They are not all built to be exclusively for parallel grinding as I suggested they may have been. That the grinders were made by Arter or not was not mentioned. Grinding convex or concave rotary surfaces has been accomplished routinely with these machines. Hope this helps.

Thanks Harold, I'll let you know how it turns out. If I set my mind to it, solutions seem to be attracted to the situation. I'm sure you know what I mean.
