Retrofit an Emco Compact 6P-CNC

Hi all!

I finally found an old

this isnt my machine

And now what i want to know is what do i need to retrofit this machine?
As an total noob all help is appricated. If you need to know something else pls tell me.

The most important, in my opinion, is to know the type of motors and drives that the machine currently have so that you would have an idea if you could re-use them. This would play an important role on the money that you will need to expend.
The type of motor that makes the spindle rotate is also important to know in the first stage.

What i really want to know is if we say that we replace all the old stuff (i havent got the machine yet but my boss wants to know how much it can be in maximum expenses to fix it)
So if i replace the old stuff can somone link too stuff that i would need?
new motors and so on. I am such a noob iit will be hard i just want to know what can be an maximum cost.

Thanx for all help i understand that it can be both cheaper and exepensive depending if i replace all stuff or keep some. But what if i keep stuff and they broke afterwards any suggestions?
Should i try to keep some old stuff and they might brake just too save some money or should i replace it all?

Okey AndyPugh ill trust you

I'm in a similar boat, right now. I have an Emco 220P that I'm ready to push out into the alley and set afire.
( I'm not kidding. The fire idea would be a nice little stress reliever from this thing ) I'm completely over this machine and its control.

That said, the machine itself is a wonderful little machine and very, very accurate. The control on the other hand, is a complete piece of sh|te...
I am contemplating a conversion for the machine, but have very little patience to undertake another project right now, as we are very very busy.

To answer the questions - they are stepper based, and 5 phase.
The original drivers are crappy, being tempermental and fragile.
The spindles are DC frequency driven, but HUGE for the machine's footprint.

I would very likely get rid of the spindle motor and throw a 3Ø motor in its place, controlled via VFD.
Either that or a servo of appropriate size. ( I would lean toward 3Ø and VFD )
I would likely replace the steppers as well, as 5 phase drivers are more expensive than necessary, too.

The biggest problem I can see coming is the question of controlling the tool turret. Has anyone done that on one of these?
Can the stock hardware be utilized or will something else be needed to be purchased and put in place?
