I have no experiance with this. any info on tooling,feed and speed, coolant or not.

in a machining center btw, 6000 rpm max.

and how hard is it to polish?

it will possibly be an outdoor item

thanks

pretty easy to cut. i suggest using highspeed cutters as they are sharper. other than that, until someone can give you specific speeds/feeds, try starting off with aluminum speeds/feeds. that will get you going.

thamks Trev.

how does that stuff hold up to the outdoor elements?

any idea.

I know they use it in marine apps but mostly cabin stuff

It lasts quite well outside. It is impervious to water, but I'm not sure about UV.

 

Ok, according to Duponts website, this stuff is pretty good. Scroll down to the technical specs.

i have seen fading on the darker tones. i was waiting to hear back from a friend, but he uses some king of sealant for his outdoor products, i just cant recall what it was.

 

i will keep digging.

Thanks Trev and Colin

Im trying to locate some drops from local carpenters to play around with

many years ago we had a large amount of corian donated to us and some small drops ended up outside in full weather for over a year. didn't see any ill effects.

 

for sanding the rep recommended a 3M product called Trizact. with wet sanding and some time you can get a very nice polished finish.

 

machines easily but i seem to recall it being abrasive on the cutting edge. also pretty brittle and chips out on corners and small parts. if 6000 is your max rpm, that is the area you should be running; and you will be slow. your feeds can also be faster than aluminum.

 

it is largely composed of Aluminium TriHydrate derived from bauxite, an ore from which aluminium is extracted and acrylic resin.
