Bench top CNC Mill. The introduction. This is just the beginning!!
Mike Makes It
I've been looking a buying a desktop CNC machine for a while but at Mikemakesit I don't buy it if I can make it so thats what I'm going to do. It will probably work out more expensive but I will be able to make it exactly to my spec. I'm looking at a working area of approximately 500x500mm. Plans are still being formulated so I've not got a figure for the Z height yet although I'm going to be using a Makita router as the spindle motor. To me the aluminium extrusion was a starting point and after a good search on the net a company called OOZNEST seemed to have what I was looking for. They cut the extrusion to the length you want which was great and the cuts are very precise. They need to be otherwise the build will be all over the place! I've got nearly all the parts I need so in forth coming videos you'll see the build from start to finish.
The OOZNEST site below is really quick to respond to questions and as I said in the video carry many parts I and perhaps you will need. Try them, you won't be disappointed.
Another site (USA) is OPENBUILDS. They have a section on their site dedicated to people sharing their builds.
