Diamond Cutoff for Alumina Ceramic

I'm looking for advice on how to properly use a diamond cutoff wheel on my surface grinder. I'm going to be using the cutoff to cut and slit alumina ceramic parts. I have experience grinding alumina, just not using a diamond cutoff.

I'm going to be using a 6" cutoff disc, .035" width (with plenty of coolant, of course). What sort of DOC should I start with? .005"?

As far as mounting the wheel, I picked up a separate mount, made a bushing, and have balanced the wheel. Is it ok to have the bushing on one side only? The mounting arrangement is arbor back (closest to spindle), cutoff, bushing, washer, and arbor nut. The bushing is the same OD as the arbor itself (2.25"), and is 6061 AL.

Any hints, tricks, etc is appreciated.

Assuming a 3600 rpm spindle.

.0025" DOC

6 fpm feedrate

If ceramic is secured well you can downfeed both directions.

Indicate the OD and side of the wheel within .001" before starting.;

"Open" the bond with an alumina dressing stick or old wheel with grit size ~1/2 the diamond size.

A 100 concentration wheel may be too hard. 50 concentration metal bond works well.

Thanks for the information, extremely helpful. I have a 50 concentration wheel on hand, so I am going to give it a go.
