Thread: Some CNC machines

Hi all. First post, so be gentle!

Here is a machine that a friend and I built for a uni project a few years ago. I did the mechanical side, and my mate did the motor drivers. It now resides in my under size workshop, in which I don't get to spend as much time as I would like to. In fact, sadly it has not really been switched on for over a year. But i plan for that to change very soon.

Have a look here:

The steppers are just big enough to do the job, but we are in the process of converting it to servos. The lead screws are ACME with nylon lead nuts. Skate bearings all over. Steel and Ali welded construction (I am lucky to have access to a steel fabrication workshop with talented welding people). It has a spindle that I was very very very lucky to get hold of.

I hope to start building another machine soon for engraving and light milling of aluminium. that way the metal swarf stays away from the timber.

So many projects, not enough time....

Rod, you are making me drool

Tim, you have a great looking CNC machine there. It would be good to see a few more shots of the XYZ's mechanical setup. I have just received a set of 305oz steppers and am looking for inspiration to construct my own machine. Presently looking at fabricating home-brew linear slides so some detail pictures of your setup would be greatly appreciated.

I am just in the process of my first CNC router build, I have never taken a project of this size to date, and I am looking forward to the challenge.

I did purchase the 2006 kit from Joe, and according to him should be ready for shipping this week. My first thought was the Jgro but I felt Joe's would work fine for a first try.

I have a million questions in my mind, but some will be answered as I build and some I will have to ask the more experienced builders.

Thanks for posting your pics,
I feel like a youngster waiting for Santa.

Have a great day!
John

Hi Tim,
Great machine and good work on your projects.

Tim,

That is good CNC thanks for the link!

Gator3535 just little too big for most of us

sorry .. I forgot to make the picture smaller .. this is only a 4x8 machine .. anythings smaller is a toy!

heres a smaller one for ya

I have been working with these machines for a few years .. would love to hear from anyone who is working in a small production plant.

Wow gator you built these machines yourself

no .. this is an omnitech .. made by anderson .. is this forum only for home builds? Sorry

No its OK mate just start a new thread, I think one or two guys on this forum may work in that area but most of us do it for a hobby.
