6.5 metre Travel.

[Firetrap]

Hi all..

Im in need of help..I am trying to design and build a 6.5 metre ( X Travel ) 100mm (Y Travel ) and 100mm ( Z Travel ) Drilling machine .. I am needing to drill a series of holes along the length of a Aluminium Extrusion. I need help with basically everything ..

I have done some reading and am thinking of using R&P . But have know idea about motors or controls..
Can anyone help or point me in the right direction ..

All advice welcome..

Well, you said all advice, I'm pretty green, but I'd look here as a start.

And the owner ?! of cncrouterparts, Ahren sorry if I'm misrepresenting you.

There is an extremely detailed build log that gets converted to R&P using these parts.

Here
CarveOne's Work Table CNC Router Build

no where near the length of what you want to build but might be a good place to research.

Good Luck.

Wow.....6.5M x travel. You will have to go R&P. As mentioned already Ahren has excellent quality items for use with 8020 aluminum extrusions. I would say this would be your best bet. The Y and Z can easily be done with basic lead screws and nuts.

Take a look around the zone to get the juices flowing.

You are going to want a gantry type machine since you probably don't want to make 6 meters of room on either side of the machine to move the material/table back and forth.

If the holes are in a row and not all over the place it may be easier to use a drill press with a fixture with stops that flip up in position to bank the part for each hole. I'm not saying not to make such a big CNC machine but something like this would be a lot simpler and cheaper. You sure need a lot of room to run a machine like this.
