cnc for marble

[yasser]

You will not do much good with the type of bolt together frame that you are showing.
You do NOT need higher speeds, but you do need a RIGID machine and plenty of water, rough out leaving 4 to 6 mm for finish cut, using Diamond and carbide cutters depending on the type of stone your cutting, marble / limestone is soft and will cut well with carbide, for granite use PCD (poly crystal diamond ) cutters, sandstone use brazed diamond tooling or pcd.




Head being cut is Limestone and cut with carbide to a depth of 16mm, the eyelet is in sandstone and is cut with PCD.
