Hello all, Here are some pictures of my recent Emco 120p rebuild. I changed all the electronics mostly for the ease of being able to get new components readily. The old stuff was just a pain to get.

The lathe is driven by a 4 pole, 4 hp inverter duty, 3 phase motor. I use a Huanyang vfd to run it on 220 volts.

I used the original encoder housing and wheel, to hold my index pulse setup. Here you can see the notch on the wheel…

As of last night, I have everything running. The pneumatic chuck and tail stock work. Speed control works (it does suffer from the Mach3 issue of over speeding slightly before settling in). I control the tool turret with an external switch.
This is my first attempt at anything that has to do with CNC. It took a bunch of time, spent many a long night searching the web, reading posts, etc. But, it kept this old man’s brain working. Now, I just have to learn this g-code, cad and cam stuff to be able to use the machine…lol

Nice looking job you've done there Pete.
What sort of parts do you plan on making ? Hobby stuff ?
The Code, CAD and CAM is a lot of fun to learn .. and very rewarding.
Some real CNC gurus here, just ask away, they are brilliant.
Looks great,
Russ

Russ, I built the lathe to make parts for a linkage system I developed for older VW's and Porsches. Last night I ran my very first program in g-code. Nothing special just a couple of passes ...cutting air. It kinda brought a tear in this old mans eye...lol

What a great looking project you've got there, Pete.
Looks like you're in the same boat as me (my cnc lathe isn't near as nice as yours). I did the same thing, build the CNC lathe first, then learn to use it :D
Thanks for sharing-

I know the feeling, the satisfaction of seeing the machine respond precisely to your every command ... well, usually. ;D
Mine does exactly as I say. I get into trouble when I tell it wrongly. ::)
Have fun and be safe Pete.
Regards,
Russ

I like the look of these wee Emcos, have been looking out for one myself for messing around with but have ended up with a different make.
Look forward to seeing the video of it cutting metal :)

Hi Pete,
Congratulations on your first machine rebuilt. Looks like you did well. This is a very good machine to own. I have an Emco C5, which I like, and have been looking at acquiring one of these larger versions with automatic chucks.

I posted a video of the machine running my first ever CNC program (Gcode)...here...

Looks like its working great, going to have to make a turret for mine :)
Like the auto collet and taistock, very handy, just have to rig up a bar puller now ;)
