Thread: new and hopeful
thought i would give a quick intro
for the last few weeks i have looked round various sites with a view to acquiring a cnc machine. i have no knowledge other than what i have gained over the last couple of weeks therefore i have much to learn. i started off by looking at evil bay and the imported versions and while looking into their reliability i was lead to this fine forum
the cnc machine will be used to make relevantly small plastic parts but i have read some comments to say its not good to cnc plastic ? i was thinking of a machine with a cutting area of about A3 size with a cutting depth of 2 1/2 to 3 inch if possible. i have no knowledge of the electrical side of things but have manufactured various things over the years in wood, metal and acrylic so building the main frame shouldn't be to much of an issue. couple this to some of the comments i have read about being able to build your own 'superior' machine for the same money as the imported ones is the reason i have decided to take this route. so i will carry on reading the forum for now but be prepared for lots of 'how do i' questions

i have no idea why anybody would think cnc'ing plastic would be a problem
so i will carry on reading the forum for now

hopefully you will ask alot of the questions that i need to ask aswell hey :D, if you want any information about ballscrews i suggest you look at this thread http://www.mycncuk.com/forums/showth...ned-ballscrews as i've just asked a few questions about them myself, i havn't got much further than this yet.

thank you for the link Wilfy. belts it is then, i have learnt something else already LOL
22-07-2012 #5something to do with the speed of the cutter melting the edge ? don't quote me as i could well have misunderstood the posting
Best advice is don't go rushing buying parts etc untill you have fully come to a design that suits your needs. If possible design it in Cad to ease the build and reduce errors from component clash's.!!. . . Call the first drawing V1 and when your at around re-vision V1.8 you'll just about be ready to think about whats needed component wise.!
Good luck and it's easy if your methodical doing it in the right order and treat it like eating an elephant.? . . Small pieces at a time.!!

thank for the welcomes BTW
Once upon a time in the deep dark recesses of time there existed.................................pencil and paper. Pre-cad we all did are designs this way. Give it a go, it may still be available.
Lots of info here. It is also possible to get plans at a reasonable price and get some one to print them out for you for you to modify to suit your self.
Of course you will eventually have to learn so that you can draw the components that you want to make.The more I know, I know, I know the less. (John Owen)
