Hi all,
A Deckel FP1 MK2 (1960) issue.
As the threads title indicates, i managed to hit the bottom of the z axis because i forgot to reinstall the autostops after cleaning. Happened after moving the machine with the table in its lowest position, wanted to raise the table the lazy way, but hit the shifter to wrong direction. In a fraction of a second I realized what happened. But too late, too stupid.
Good thing, the shear pin snapped, so no damage there.
Bad thing, the table was stuck at the bottom. I released the bolts and tapered pins on the block that holds the elevating screw and bevel gear, and some gentle taps, to release a bit of pressure. And turned with some force (no tooling, but turned the handwheel with two hands to get the table loose.
It worked, but the z-axis handwheel turns not smooth anymore. It feels like a constant friction in the elevating mechanism... The powerfeed turns ok by hand.
1) Could It be possible the z axis nut has been deformed because reaching the end of the threads on the rod?
2) Or worse, did I bend the handwheel axis because to much force?
3) Or... could it be possible something happened on the z axis elevating screw rod? Misaligned bushing?
I read some threads on 'hitting the bottom', but none says anything on a z axis handwheel with friction afterwards...
