Jet 13x40 CNC lathe conversion with Acorn Control and DMM servos

Post by gt40 »

Just a few short clips of my Acorn cnc lathe build.

The machine is a Jet GHB 1340a that has been converted to CNC, using DMM Dyn2 servos and drives, ground ballscrews. I recently upgraded it to an Acorn controller.

I added a Omron 2000 ppr encoder with 3d printed gears to avoid plugging the back end of the spindle..



Enclosure with sliding door:



Threading 6061 at 1500 rpm:



I previously used Mach 3 and 4 and the Acorn is such a massive improvement.

As an instructor at a small non profit teaching facility, the Bainbridge Barn, we are adding a slant bed lathe from dynamics and liked the Acorn so much, we are retrofitting it with a second Acorn to replace the aged Fagor control.

Are you running a servo spindle, VFD, or DC?

Loved the 1500RPM video!

I am running a 3hp Lincoln 3 phase with a Westinghouse vfd. The centroid spindle control is really nice...
