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
