Application in ink stone, stone, marble, granite engraving.


A stone CNC router is a type of CNC router machine designed for marble, granite, artificial stone, tombstone, ceramic tiles, glass machining, polishing for arts and crafts, etc. The biggest difference between the different types of materials, is that you have to have certain “bits” or “inserts” to cut different materials. You wouldn’t use the same bit to cut stone as you would to cut wood. There is bit call as diamond tools with different diameter 4mm,6mm,8mm mainly used.For wood CNC working, you could use a softer metal bit, but for Stone CNC working, you would have to use a much harder metal bit. The bits/inserts have to be harder than the material it's cutting.
