Show"N"Tell ( Your Machines) / Khadgar's DIY CNC machine
« on: December 16, 2012, 05:05:58 AM »
Hello everybody, i signed to this forum yesterday cause i decided it's a bit time to consult with people who have build their own cnc machines and not just look pictures of cnc machines and consult with only myself about design. 
I have changed 3-4 different designs from really complicated ones to simpler and easier to make and hopefully this last one will be really last before i start to order some parts. Good thing is when you are a bit limited with money you do thinking first and work later so i'm hoping i avoided most stupid mistakes from earlier designs.
Here is latest and i'm hoping last design i made,worktable is fixed while tool will be moving,so that X axis motor will break a lot of sweat to start moving gantry. I made this in CATIA and calculated weight is around 20kg's.
So faar i got only linear bearings cause i was lucky to find them really cheap. Every other part especialy ballscrews won't be that cheap...
This little machine is supposed to have working area around 450x650x200mm. Plan is make it for cutting wood,plastic,aluminium maybe some other metals but i doubt. And last but not less making PCB's. As you can see it should be all-rounder cause i love DIY stuff and i'm building my own hi-fi audio stuff for hobby/fun and i just like to do everything from scratch so all-rounder is needed.
This is for start, i'm hoping in next couple of weeks i'll place order to some small company that makes cnc machines to make me aluminium parts for X,Y axis so finally some assembling will be done.
