Dismantling, cleaning and replacement of bearings in the ATC. A few photos of the process

 

 

 







 

 

 

 

 

We continue with X and Y . Disassembly, cleaning, replacement of guide balls and replacement of support balls. (took a long time to find the right size balls )

 

 

And already cleaned

 

 


To be continued  

I'll upload more pictures tonight
 

Each ball screw has 3 bearings 30TAC62 , the screw is secured with an additional body (grinding cylinder with dimensions of 40-60mm ).

 

New servo motors for spindle and axis 

The drive is with Etercat and mesa cards for spindle and I/o port. 
 

 

 



I decided to make a foundation as shown in the machine documentation.Because my foundation was too bad…
20 cm of gravel and 60 cm of concrete.  


 

 

 



 

Looks great! I am looking to do the same soon.
May I ask where you are sourcing all your replacement parts from?

Thanks.

Which part are you referring to?
Do you have the same machine?

The machine has been moved. All 6 screws fit well.

 

 

 
 

Hi,
Anymore updates?

I have an MV-40b with Fanuc 0m that might need converting soon

There's nothing new. I'm working on the lathe from the other topic.

This might sound stupid. Ive just done a similar job as you although I didn't bother with any mechanical parts as my jr has been used in a school and is still like new, only problem I have is I have one pice of metal I can't find out where goes.
Do you have any idea where this goes.
Thanks in advance for any help!
