Stuart, sadly this is not documented. Traub keep these things very close to their chest - it's like getting blood from a stone. I'm absolutely sure that they have internal documentation that would have helped hugely over this resurrection, but they only seem to want to respond to specific points :)

Congrats on the wedding anniversary - we're coming up to 40 this December

Steve, good to see you back - good holiday?

lordedmond:
thanks for the Congrats as with you Lathe keep at it and hang in there for the long term

Yes sir. Went in a boat in an underground lake in a cavern, good friends, etc. fun for 7 year old daughter. 38 hours of driving for me :loco:. Good to be back, too, though.

So to fit that rather nice chuck, I need a flange to convert from its 140 mm recess to "Din55026 A6" which is what the main spindle of the machine is.

Options were a/ Make one from scratch b/ Buy an A6 backplate and machine it to fit or C/ Buy the correct one from Schunk

To get the precision necessary I drew back from a scratch built one, and the only A6 backplates I could source were cast iron not steel, and the supplier couldn't quote their maximum speed.

So I went (the expensive) option C and got one sent from Schunk in Germany - duly delivered by UPS this luchtime

awemawson:
Phew - it fits the chuck at least ! Just as well as it cost me somewhat more than the brand new chuck and about 15 sets of brand new jaws :bugeye:

Now the next issue is that power chuck use a pulling motion on the hollow hydraulic cylinder that operates them, whereas the collet chuck currently fitted uses a pushing motion. :bang:

No problem - there is a reversing valve on the hydraulic manifold specifically for this situation. Ah - a drawback - that also reverses the direction of the 'opposing spindle' hydraulic cylinder. :bang:

Quick bit of nagging to my Traub mole reveals that there is another valve on the opposing spindle to reverse the direction back to original - well I think that's what he's saying - sent me reams of info and a broken English explanation (inifinately better than my smattering of German)
