AT-300

Hi ya'll

I am new here.

I have an AT-300, its an older machine. I am interested in converting it over to cnc, to help run simpler parts at work. The work the machine is doing right now is mostly threading and turning wooden taper plugs. I have heard a few things about ELS and that may work. Where can i find info or parts to complete this project.

Although it would be cool if it could make more complex parts.

Thanks,
Tyler

Hi,
I have a AT300 that I have converted to cnc.

send me your email address and I will send you some photos.

Cheers,

Here are some pictures of my AT300 CNC conversion.

I Used 3x 282oz in steppers which seem powerfull enough however I think 2:1 ratio is the the best for all gears.

This mill has 2 weak points.
1. The brass Y-Axis nut on the treaded shaft is prone to wear.
2. Back lash on the Y-Axis shaft bearing.

Future plans will be to improve this some how.

The Modifications I made didn't damage/alter the Lathe so I can remove the motors later if I decide to sell it.

Thanks for the pictures, nice work.

tt-boy, old thread but do you have any updates? Locking into doing something similar with my machine :-)

Tony,
I had several attempts at trying to convert this machine to CNC but it was never very accurate.
The limitation I had was the Y-Axis had to much backlash in the bearing and the Z-Axis was difficult to drive through the rack and pinion gear.

Later I replaced the X & Y-Axis with a lead screw but eventually converted the lathe back to manual control and move the electrioncs over to a CNC router I have amost finished.

Maybe all the issue I had was because my machine was second hand when to got it and it was all a bit worn out.
