Any ideas what that "timer" looking unit that was above the lubricator that you removed did?

Good catch!  Its an addjustable pressure switch to let the control know that Air is available.  

I removed it from the system as only the ATC and Draw Bar needs shop air and these faults are captured and mitigated in the ATC software control by insuring each Home and Extend operation completes before the next step.  Just trying to keep the fault logic simple.

Thanks

Can you add a picture of the way cover between the table and Z axis? I need some ideas for my mill.
Great work as always!

Wow, that's a lot of work! :o I can't imagine the man-hours that have gone into it!
Just curious, how does your tool changer go to the correct tool if it's only a simple AC motor that can go forward and reverse? How does it know how far to rotate if the next tool is say, 5 tool spaces away?
Thanks

Thanks!   

All the ATCs that I have seen have a Geneva Mechanism for this reason including this one.

Hope that helps.



Thanks

The disadvantage of Geneva type ATCs is them being rather slow. It drivers one crazy watching the turret stopping at each position when setting up tools.

This is Rear Y axis way cover.  This was the hardest one to repair as it was all smashed up.  So far it seems to be working good.

Thanks

Looks good, Joel.

Question for you, do these have a "wiper" in them of some kind, or are they just metal -to- metal scrapers?

Dave,

There is thin rubber wiper between each cover.  The goal with it is to keep out the all the coolant too.  

Thanks
