Milling Durastone material using CNC

[arazelan17]

Could anyone help me to calculate the right RPM and Feed Rate for different size of endmill for durastone milling purpose?

If you find the answer elsewhere, could you post it here? I need the information myself. Where can you get the durastone at a good price?

[arazelan17]

OK...


Sorry, I got the material via my local vendors, which I don't know their sources.
you should know also that there are many types of durastones available in the markets.

there was someone on here making turrets for model ships out of that artificial stone thing, I think? he should be able to help. there are even pictures but I don't know the thread off the top of my head. it might be worth you while sifting through the threads in either diy routers or diy metalworking machines. good luck!

but it's "synthetic granite", does that count?

[arazelan17]

em, I dont think that it is a synthetic granite material, but it is an epoxy glass material (if I am not mistaken)...

What type of tooling are you using? We mill most natural stones and Cambria Quartz Surface in our shop using different types of tooling and feeds & speeds for each.

Durastone is some of the nastiest material i have ever worked with , first of all i will suggest using a mask and long sleeve shirts and don't do anything to try to get the fiber glass out of your body... take a cold shower and sleep it off. after some years of working with it you will get used to it. lol. well i think about 150 SFM its the recommended. but i got my own theories. if using a 1/2 carbide endmill try 450rmp at a 25-35 ipm, but it all depends on how you are holding your material. 1/4 endmill 950rmp with 15ipm that should give you and idea. if you have any more questions be more specific in what you need to know and ill see if i can guide you in the right direction
