It's one of those stupid/crazy CNC lathe projects.  If I could turn back time, this project would not exist.I will try to upload more pictures but not everything is documented ..

We bought an old machine probably 2 tons of iron and immediately begins disassembly, washing and painting  

 

 

 

 

I threw out a lot of parts from the gearbox

 

 

This is the first layout of the electrical cabinet

 


 


I have reached the maximum number of files allowed .I will continue in the next post

Here I am sanding the back end of the spindle.

 

I made two parts that grip the spindle Pulley V-groove .This part has a cone from the outer part, the second part (not in the pictures)  presses the first part to the axis of the spindle.

 

 

I keep the original oil pump. It was necessary to make several parts.

 

 

We put linear guides. They had to be level and make holes for threads.

Here is the new version of electric box. Parker Hid8 servo drivers are locked. They no longer communicate with the computer and the manufacturer does not say how I can unlock them. That's why I bought new motors and drivers from China.

 

 

 

Here is the laser cut control panel

Looking nice.
And i need help, professional help, i was looking at pictures and started thinking "hey i could do this to my manual lathe"... i have to go past the Mazak to get to manual lathe, Mazak being already CNC and retrofitted and working, sans the hydraulic chuck! :)

Thanks!
Yes, we all seem to have a professional distortions :) :)

A few more pictures of the control panel.

 

 

 

 

 

It's not perfect but I like it :)
First there is a primer, then a paint base and clear varnish. Then I engraved it on the router. I used a white paint base for filling. But it would be better with a white body filler

Great project, and nice workmanship! The control panel looks great in the photo!

Is the board with the orange heat sink an HDMI to LVDS board for the display?

Yes, this is the display board. By modern standards the display is very small 10.1" :) with 2k resolution .

My CNC lathe is a converted manual, but I kept it a lot more original in some ways, and much less so in others (I had a bunch of custom castings made to replace the apron and the feeds gearbox, for example)
For the kind of projects I do the layout of a conventional lathe, without full enclosure, makes more sense.
