I had good results sharpening by hand and by machine with first checking the drop to the planer/flat blade. and bumping the chippers (high points)on the surface grinder in a V block or out of a TC grinder work head to flat grind them all to the same height.. Then by hand or TC grinder make them sharp.
With not having a way to make the chippers the same height they are a bugger.
Never did a wave type..But for them likely I would flat circle grind the points the same, and then come in with A die grinder to wike away that land to sharp.
Yes, any sharp HSS you have to not get them hot, The sharp edge can get too hot.
I once had about a 150 piece order and tried another 46k wheel (a Bay State) and unknown to me the edge got hot and they dulled quickly, good it was a best customer, and he gave me another chance.
I was using a 46K Norton wheel that I went back to..and later found a 46 L Carordrum wheel that proved to be better than the Norton.
