Check with HIS but I'm not aware of anyone doing it. I've always thought of those things as consumables.

Expensive consumables. HIS recommends taking a carbide stone to the plates when they get worn. It'll prolong the agony for a while.
I've had plates last 10 years (the ones I kept away from the students!).

well, exposing diamonds is one thing, refurbishing is something else. All my laps are really fast at first but, depending on how your diamonds were attached, they have a distinct life span. Comparative observations about when they're shot..

I'm going to go out on a limb, and say nobody does this.

I agree with Pete that these should be viewed as consumables.

Marty is correct about the HIS recommendations.

The issue with the carbide stick is that the process is really meant for diamond tools that are sintered, not electroplated like the discs in question. It's a way to coax a little more life out of one. In my experience it would come back to life for about five minutes, and then go back to cutting poorly again. Bear in mind that most of my experience is in a student setting (see Marty's comments again), or rental shops.

It's really more about how they're used. Who's using it, and what type of work is done.

Sounds like your wheel is on its last legs To get a little more life from it I'd first try one of those aluminum oxide dressing sticks to see if removing glazed on glass makes it perform better. If that doesn't work, I'd try running the wheel in the opposite direction. Either of these should give you a few months of marginally better grinding before you fling the thing into the dumpster.

Olympic Color Rods has some really excellent heavy duty diamond wheels. I use a 60 and 240 and they're beasts. They need some wearing in (as do all) but after a few feet of breakin they work great.
