Diamond belts

I've heard about one someone was making years back but it was $150 for one belt so I wasn't interested lol
 
Still the same price. 95€ for thin resin belts and 150€ for thicker electroplated ones. I'm considering it because VC are going on my nerve.
 
No experience, but the knifemaking guys here in Austria were selling off some rests at 25 euro/belt, apparently new price was 50 euro/belt, but only if you take a full package (20 belts).
 
Apparently they came from 1a abrasives gmbh. If you contact them, let me know, I would be interested to try a couple, maybe we could split with others if there is interest.
 
Diamond won't be good for grinding steel, the carbon it's made from wants to combine with iron at high heat. Cubic boron nitride is what you want.

Water cooling. CBN's are way more expensive.

Unless you have 1000 psi coolant you wont get away from the localized heat of the diamond cutting through the steel. N navasky is correct, diamond is not ideal for cutting steel when any kind of high heat is present. It will break down and get stripped away quickly. So I doubt heavy grinding (sparks) would work at all.
 
I tried something on Apex ultra and Z-wear. I used an 800 grit cork belt and used my stroping mixture of 5000 grit diamond powder and hand sanitizer gel. It was very messy, but worked. Luckily both those were only San mai I wouldn't want to do a whole blade that way. I would have used a lower grit if I had it on hand. Messy.

Finishing only.
 
Might work well then. The struggle would probably be keeping them from plugging up and not really seeing any extended life.

In the world of machining, diamond coatings and PCD inserts are only really used for very abrasive materials like carbon fiber, wood or some aluminums.
 
So, it's good for carbides but the softer matrix will clog them up. Good to know. Seems like ceramic Trizact is the way to go.🤔
 
I have been using the ceramic Trizacts for a while on S90V and Magnacut at 64 HRC and they work pretty well and last a while. Norton also has the U936 as well that are ceramic, too.

After the A16 Norton Ceramic U936's, damn those pesky deeper scratches in S90V!

Looks like it time for diamonds :D
 
Talked to a maker at blade a couple years ago that made beautiful stone handles and he said he used diamond belts to grind and shape the stone.
