Hello
I been thinking about building a cnc for my business,which is monument business.
the main engraving will be on soft marbles and if it can just make small touch engraving on black granite its great.
1)please let know what spindle rpm is recommended for engraving on marbles-should it be slow rpm or fast?
2)do u think a 2.2kv spindle is strong or we need a stronger one?
3)what typ of rails and motors recomended?do u think a round rails with step motors is ok?or i need gear rails?with servo motor?
4)what bits i need to engrave on marbles?and where is a good place to buy?shoud it be tungsten carbide blades or hss or vidia blades for marbles?
5)should we use water when we engrave on marbles?
6)whats the speed recommended for engraving stone and down rate?
7)any recomended structure is welcome
thanks in advance
