Anyone know of any places that will take a grinding wheel (20x8x2) and pre-dress an angle on it for me? I have a bunch to do because the only stock wheels I can get are straight and I don't want to waste time doing them on my machine here. Wheels are AlOx Vitrified bond. Thanks.

if it's ongoing, you know you don't have to do it with a diamond dresser ? You can just crush roll the shape, goes fast and easy ?

I used to take wheels to be shaped and speed tested to Mach-b back when they were in Warren Michigan.
Back then they had a steel wheel that was about the size and shape of a small Tc grinder cup wheel..that steel wheel was pressed against a rotating wheel and would crush the new size or shape to the wheel.
Likely you could have a wheel vender send your wheel to Mach-b .. and then Mach-b sends them to you.

A wheel crusher is pretty simple.. one could make one.
I don't know if every wheel can crush...but Mach-b crushed every wheel that I took to them.

I'm hoping it's not ongoing. We recently purchased some used grinders and the ball was dropped on ordering wheels so now I am just trying to get something that's in stock in the grit I need. I have placed orders for properly shaped wheels, they are just 12-20 weeks out depending on who I go with.

Do you have a fancy form/shape or just an angle?

If you have a number of wheels, it seems that somebody local will dress/shape a box of wheels for a fair price. An old clunker mill or tc grinder can be set up to dress/crush wheels... even a lathe can become a small grinding wheel crusher device.

I see that you don't have your location posted, that could be an asset to getting help .

It's just an angled face with a small .250" shoulder. My machines are angle head (20 or 30 degrees, respectively) but the in stock wheels are all squared off.
And I am in Eastern PA (Philadelphia) but unless there's someone I can hand deliver to shipping to New York or Minnesota isn't a ton different.

If you had witnessed the simplicity of what Mach b had at the old warren shop on Stephens Rd near Grosbeck.
Big wooden box with a variable RPM spindle for wheel speed testing, a rotary table with a swing arm, and a crusher wheel.
How many wheels would be in a lot ./ would it be worth a local guy to set up a wheel shaping service in a garage shop?
A simple machine might be a Trailer Axle bearing mounted on a scrap lathe bed with a swing arm for crushers, using an automotive flywheel as the rotary table....and a simple lathe for making shape crushers.. a diamond follower for diamond-dressed wheels. Likely fudge up the whole shebang for $500.
The old-fashioned Carborundum 8" x 2" x 2" Dressing Stick makes quick work of roughing in a wheel.
