i have been asked to give a chamfered edge to a piece of marble.Could you give me some giudence.?

Question

It is to remove the sharp edge of the cut marble and give it a chamfered edge instead.

could you tell me what the chamfered edge should look like - the piece of marble is 20mm thick ?

Answer 1

Diamond discs for tooling stone are about
$120 a piece and you need about 6 different grits and a wet sander, and the skill to use them. The tools needed will run you a minimum of $800. I think this is a job to sub-out to a stone finishing/manufacturing shop.
A chamfer edge is a flat bevel at 45 degrees the depth of the bevel can vary depending on the look you are looking for.

Answer 2

Marble is a soft stone and is worked generally the same way that wood is worked. A strong router would do it if you can get the proper bit that you want.

If it is small enough to handle, you can get a diamond blade for a table saw and do it that way if all you want is a slight 45 degree cut. If it is a little rough, sand it like wood.

Marble is pourous and easily stained so whatever you do, you will have to seal it with something to keep chemicals in the air and cleaning chemicals from the surface of the marble. regular vinegar will etch it and probably windex with vinegar would also. I would recommend a hard carnuba was and some heavy polishing after cutting.

Answer 3

This is not the type of job for an amateur. A pro should have the correct tools to use. Care must be taken because the marble could crack plus it is extreemly heavy. Good luck

Answer 4

Marble is soft limestone. I use a carbide file on it, that works very well. Then i use a sanding block and start with 600 grit wet dry paper using it wet and then final polish it with 2000 grit wet dry paper using that also wet.

Answer 5

use the same tool than you have to sharpen a knife if you are not a professional. Go very slow and smooth, because it may break.
