I hope someone can help me out or give me advice!!
I am making a rug using 2 colours of marble. The material I use is tumbled 15x15cm marble pieces.
I need to make a design which implies that I have to "cut" (Diamant water cutter) the 15x15cm tumbled marbles into smaller pieces. However it leaves a sharp edge when cut. How can I get rid of this sharp edge??? I want the smaller piece to also look tumbled through and through.
Do I need to use a sly machine? A tumbling machine? Or any other advice??
Thanks in advance!

Can you post pictures or provide a link to show what you are trying to make? Is this like a mosaic or like a chess board pattern? To just smooth the edges of pieces this size (hard to imagine you have 15x15 cm tumbled anything) you would need to gring them down starting with a coarse grind and working down to finer levels. A machine like this could do the job  It would help to answer your question if you could show us what you would like to do. There may be an easier way! |

I'm going to assume you are using tumbled marble floor tiles? If so, and if no one here has experience with flooring, I'd suggest you contact the manufacturer or the place you bought the tiles from to find out which is the best process for retumbling the marble tiles.

@ Eileen
I am indeed talking about tumbled 15mmx15mmx10mm tubled mosaic cubes used for flooring.
The small cubes are already tumbled (I also have them polished but will use tumbled this time).. but because I need to cut them into smaller pieces I can only use a diamant cutting machine.. which results in rough edges. I need to get rid of the sharp edges..
I will try that machine in the first answer.. hopefully it helps! thankssss

A diamond wheel will remove marble like it was butter, but that sounds like a massive amount of labor.
A Dremel or Foredom rotary tool would work, or even coarse grit sandpaper on a sanding block would break the edges.
Carbide router bits come in ever kind of profile you could want, but whether they'd be safe to use on stone... I'm not too sure about that, and you'd have to make some sort of jig to be able to use a router on a 15mm piece.
Faced with a problem like this I think I'd change my plans. Doing detail work on countless 15mm pieces doesn't sound fun.

Ah, a mosaic! I figured as such but wasn't really sure  Yah, I'd go with the machine that captbob posted. Just remember that the edges you do with the machine probably won't match the tumbled edges. Unless you are leaving only parts tumbled? Outer edges? A few years ago I did a small mirror mosaic with glass pieces and it was a hoot. I would love to see what you are creating. Eileen |

There is a file you can get at your flooring wholesaler that knocks down the sharp cut edges of your marble. Most times it is easier to put the file on the floor and hold it with your feet, then move the marble back and forth on it to knock the edge down. The file is relatively cheap if you dont have access to a grinding machine.

World of difference between 15 cm and 15 mm tiles!
A file and maybe some wet sandpaper or a dremel tool should work fine. How many of these you have to shape?
