Thread: Hone cutting vid

What kind of stone? What kind of blade? What surface speed? Why dry?

Those are all very valid questions, but the vid is not mine and I can't answer them.
I thought that the dry cutting of the stone would be interesting for people to see. I somehow imagined this would be done with water for lubrication.
I'll see if I can get more info.

I used to work at a quarry and we used water to cut everything. My cutting blade was approx 8ft across, we ran 2 in parallel, and it wasnt the largest we had. A friend of mine still working there says in years gone by they used to makes hones there but its all building stone now with the occasional piece used for sculptures. It was, without a doubt, the loudest place i've ever worked

Great vid!

Even more interesting is where the off switch is located. I certainly hope there is no emergency.

I been there! He was out of town on business though, so all i could do was look. His wife's very nice, though.

I'd take one of those Aotos in a heart beat.

Wow, those stacked tubs of stones is about ready to topple over. He should send them to me for safe keeping.

I would wager that the teeth of that saw blade are diamond impregnated. Due to the extremely slow speed that the blade is turning I don't imagine that heat build-up is a problem which would explain why there is no water cooling. Aiding that would be the wide gullets which would allow the stone dust/grit which is ground away from the cut to easily move away from the cutting point. Again, this eliminates the need for flushing the cut with water.

There was mention of the cut surface of the stone being slightly rough and in this I can see a last advantage in that would make for slightly larger stone dust/grit coming off of the cut, which when combined with the slow stone cutting speed would probably allow most of that junk to just fall down quietly within the saw instead of swirling around the operator in a lung-choking cloud.

Of course, this is all mere conjecture from watching the video.

here an interesting link, of a blog about stones, same dry cutting done.
