Sticker shock

[Martin w]

So at work I have an edge banding machine that applies pvc or abs edging to pre-cut plywood panels. It has a pre milling feature that mills off whatever thickness of edging you are applying. Normally 3mm. They were starting to get dull. They are diamond PCD inserts, which I have gotten three years of steady cutting.
Called my supplier. $92.00 each. I need 24 inserts in the cutter head. Almost $2200.00.

I ordered them, but. My question is , at home I have a cutter grinder / surface grinder (KO Lee ). What type of grinding wheel would touch these inserts up? I see online you can ship your entire cutter head and have them sharpened. So they must make a wheel to do it.
I would make a fixture to hold the insert and just lightly do a grind So they are all the same. I have the diamond cup wheels here for carbide sharpening would they work?
Thanks
Martin

The Diamond wheels are about the only thing that will touch a PCD insert. I tried it on an older grinder and found the wheel would climb rather than cut and had to put some down pressure on it. the results were less than optimal.

here is a link I had in my bookmarks. http://www.superabrasivetools.com/grinding-pcd-tools-and-sharpening-pcd-tools/

good luck.

S+1 to @TheCNCNerd sharpening PCD inserts requires very large pressures with diamond tooling that I think is outside the range of most hobby machine shops.

Reading through the link you provided, started to make my head hurt. Dunno what language it was translated from, but the translation is some pretty bad work!
Brutal, trying to follow it through.

Yes the translation is pretty rough pretty sure it is translated from Chinese I have some Mazak documentation from the 70's that would give you a good laugh.

Nah! The 'funny' of that wore off years ago. These days, I can't be bothered to delve into the likes of that, unless I REALLY need ANY info I cannot get otherwise.
Hells bells, I have got to the point where even the Youtube videos that are being read badly by a bot, (usually replete with bad pronunciations of relatively common words, and horrible syntax) just get bailed out on, usually tagging the thumbs down button on the way to the exit

My sense of humor is such that I am still amused by flatulence so it only stands to reason I would see the humor in a truly tragic translation.
