CNC Crash

Hello everyone,
I had a minor crash from which it resulted a big problem.
The sub-spindle collided with a tool post and now it is not centered with the main-spindle.
I've checked with 2 calibrated bars of 4 mm diameter and set them apart by 0.25 mm but I managed to insert a 0.6 mm plate between the bars, so they are approximately 0.35 mm apart.
Is there any way I can reset the machine to its factory reference points? It's hard to imagine the sub-spindle head shifted from its place from the collision, or did it ?!
I have attached two pictures showing the unalignment between the sub-spindle and backwork toolpost.
The machine is a Tornos Swiss Gt13 with Fanuc 32i
Is this an mechanical problem or can it be solved by reseting something.

Mechanical issue if the two spindles aren't aligned. And yes any crash can do this. The sub spindle must be re-aligned.

Yup, you need a full alignment. This can be compensated with the Grid Shift (at least, on my Citizens it can), but I wouldn't recommend it, that's a kludge, and if you hit it hard enough to knock it out this much, an alignment is the best fix.

If it has any taper pins I would pull them and re-align. Most likely they aren't parallel to each other anymore either. I'm not familiar with this machine but I would also check the alignment of the tool post, as a crash on a turret machine can easily move the curvic coupling.

I believe the sub on the GT13 moves in 3-axes.

If you chuck up a ground pin and there's no angular misalignment, it's possible one of the motor/ballscrew shaft couplings slipped. John Grimsmo has this machine and mentioned something like this happening recently in his podcast.

I had something similar happen on a linear pallet changer where overhanging fixtures collided and the coupling slipped. In my case it moved a lot more than .35mmm. The coupling was checked for tightness but not reassembled, and the actual fix was done strictly in software, by setting a new home position in the parameters. Took 15-30 minutes.

I bumped the subspindle on a "regular" lathe as well. No parts needed replacing, but there was angular misalignment which required a full realignment. Took an entire day.

Thank you for the replies.
The sub-spindle has 2 axis, X and Z and there's a tool post which gives it the 3rd axis Y.
The collision was done on a short distance with the Y tool post, about 20 mm, its hard for me to imagine it made this much damage but apparently it did.
I will talk with the supplier tomorrow...

What kind of equipment would it be needed to do such a re-alignment ?
