(SOLD) Deublin ltd pneumatic chuck for Mirac PC

[dhop125]

I have recently pruchased a Mirac PC with pneumatic chuck fitted, however for my needs a manual chuck would be much easier.
Deublin Ltd is stamped on the back of the chuck.
4" 3 jaw chuck, 4000 rpm max, 6 Bar max pressure.
I have the back plate and all the solenoids etc to make this work.
chuck appears to be in good conditions, although one of the jaws has taken a thump at some point.

Ideally I would like to swap for the appropriate manual chuck set up for a mirac pc. Failing that I may be open to offers.

Open to offers?

I have now sourced a manual chuck, so yes! I would be open to offers.
I have some more info on the chuck too, I will post later tomorrow.

Very cool! I really have no idea how to price a chuck let alone sight unseen lol, do you have an idea what price you would be happy with? You mentioned it has been bumped, so I'm not super confident I would want to pay an arm! Could you post pics?

So a little research has told me that Deublin is the company that made pneumatic coupling on the back of the chuck.
It is actually a leader chuck systems brand air chuck - although their website is pretty terrible as all the technical info is missing so I can't be sure what model it is.
At some point somone has hit one of the jaws (seen in the pics). could easily be replaced, but it holds a good tolerance as is anyway.
I have attached some pics of the chuck and control solenoids.
Top two lines are for the door actuator. The bottom line is for the chuck. Air supply comes in at the top.
Unit is wired to the crontol board, so that it operates from the appropriate M codes.


If you need any more dimesnions let me know.

What is the diameter of the rotary union behind the chuck? I would like to know if I can pass that through my spindle. That bump is definitely concerning. if you have an opportunity to mount an indicator on the chuck body and tip on the jaw, how much can you wiggle it? I am in the US in Wisconsin, where about are you based?

[dhop125]

Union: 28.40 dia x 35.30 to the register.
Brass fittings are 19.20mm
The jaws don't wiggle as they're under tension.
The jaw can still be repositioned as you would normally.
I'm in Scotland. International fedex would be around £75.

[dhop125]

The chuck jaws are soft jaws designed to be machined to hold a specific bar size. You could still buy soft jaws for them.
