Very impressive indeed.

Started my third milling machine to replace my wooden one, I'm in about two days of the build and need to go hunting for some more bolts. This one is a light weight version of the big one, mainly it's going to be used for wood, foam and aluminum. I was wondering if it would machine steel if it wasn't pushed to hard, mainly to save cutting intricate parts out with an angle grinder, so precision wouldn't be critical. Any thoughts?

Attachment 311826 the table still has two steel box sections to go in the middle plus the mount for the ball nut, hopefully completed this weekend ;-)

Nooooooooo not round profiles!

Nooooooooo not round profiles!

At least they're supported round rails which isn't so bad.

Unfortunately when I began all this about a year ago I always intended on building a small machine. Anyway small machine ended up getting stronger build than the rails could take. Hence this one was its light weight equivalent! 😁

Even this one I'm seriously temped, getting some THK rails for this one too

Are you going to stress releive the (cut anything) frame?

Also you could fill the tubes with concrete to dampen the tubing, tubing tends to vibrate.

You could make this a serious performer.

Great build BTW

Thanks 69mach1,

it will be definitely filled with either concrete or oiled sand, not sure which yet. The frame will be rectified now that the extra steel is welded on, stress relieving I'm not sure where I would go to get it done

Finally got the plates welded on which will be skimmed, unfortunately other projects have slowed this one down but, hopefully it's back on track! Attachment 314264Attachment 314266Attachment 314268Attachment 314270Attachment 314272

I will have a look for HIWIN rails on aliexpress now, thanks for that! Does the pre load have anything to do with table weight?

The aim is that it will be ground and scrapped. Considered stress relieving it but not sure where in France I could take it.

Hi Sam
I am watching this thread from am a week ago and wanna wants to build similar type machine, can you give me the dimensions or any sample drawing?

[aarggh]

Out of curiosity have you checked the thickness along the length to see how much deviation there is?

cheers, Ian

Hi Sam, i think your build is awesome so far! How about an update? I am also about to get a gantry style mini cnc mill build going soon. Keep us poatsed! Doug

Hi sam, what is oiled sand exactly some kind of sand with epoxy?

[i_am_fubar]

Dude. Legendary build. If i ever get around to a gantry design, I'm going to be taking some inspiration from this thread

And yea, the round rails are a weak point. Not so much the rails themselves, but to have all that steel, then connect it together via the aluminium support beams the rails are on will give you a massive hit of accuracy under load.
