A friend has a triangular, 3 faced honing stone. Like this one from Mcmaster; "4505A1 All-in-One Deluxe Oil-Bath Sharpening Stone 11-1/2" X2-1/2" X1/2", Alum Oxide & Silicon Carbide In stock at $209.73 Each"
The surfaces are worn from use and he wondered if I could surface grind it flat again. He estimates that removing .030 would true the surface.
I do not have a diamond wheel for my surface grinder but do have a white oxide one. Will that remove the material and resurface the stone?
Bob
My guess it that would clog the pores in the stones & they won't work well. I have a cheap set of diamond "stones" from HF (diamond coated mesh on a sheet of plastic backing)I use to flatten my good stones, or others here have suggested a single point diamond dresser in a flycutter.

Aluminum oxide is much softer than silicon carbide, so, no, it won't work. Even grinding aluminum oxide with aluminum oxide isn't a good idea. I expect you'd remove more from the wheel than you would the stone. Diamond is the answer, and even that will be a little bit hard on the diamond wheel.
Can the stones be turned over?
Harold
Thanks Guys. I like the diamond in the flycutter idea. I'll try that
Bob
My friend brought the stones over today. I set up a diamond point in the boring head. I covered the machine surfaces and kept the shop vacuum running pulling away the dust. The diamond resurfaced the stones and they came out absolutely perfect.
Thanks for the suggestion.
Bob
I have years of precision grinding to my credit----
I learned something valuable today!
