It's bathroom remodel time. Is it possible to use a cnc router to cut the ceramic floor tiles or would it be wiser to rent a wet cutter ? Rotozip offers a dry cutter that claims to do the job.

Hi,
i'm not the best user to give an opinion since i don't have a cnc yet and don't know what type of machine you have, BUT based on the experiences on ceramic cutting, i really don't think that using cnc is a good idea. Ceramic is very hard to cut, but the worst is the dust it makes, very thin and abrasive... may ruin some moving parts of your cnc... Wet cutting is always better.

Just my opinion.
Cheers

yeah, that dust looks nasty. My router can't tolerate liquid and my mill can't spin fast enough for diamond tools. On to plan B or possibly C.

It will rip through a ceramic tile in seconds. Even if you had a Bavelloni CNC router equipped for wet cutting of stone and ceramic, I'd still recommend the tile saw; it's the right tool for the job. And forget about the roto-zip - it's okay for the occasional fancy curved cut, but it will fill your house with dust very quickly, and works very slowly, at least on stoneware tiles. Use your CNC router to make some fancy woodwork details; it's great for that sort of thing.

Why not vacuum up the dust by holding the nozzle close to the bit?

Most diamond incrusted blade only need about 3600 rpm to be used. After looking at Rotozip seems they use 15000-30000 rpm on their tools.

I know. I know. Two years too late, but I saw this thread, and then found this video. It is possible with heavy flood coolant to cut granite with a rotary cutter on a CNC. I couldn't imagine trying to do it dry though. Skip to about the 6 minute mark where they have it on the second machine.
