Since the other topic was about the manual version - the P50, I thought it would be more appropriate to make a separate topic for this version of the machine, since there are quite a few differences, idea of the thread is to provide some reference material since there seems to be not much about these machines on the web
History of the particular machine, I bought it from an auction in Switzerland, just on a whim, out of curiosity more than a need (and because Milacron praised the quill of the P50 so high ), auction pics:
Fehlmann support were gracious enough to send me users manuals for the P51 and the TNC155P, and they also were able to provide me with machine parameters for the TNC, all of which are available here:
Fehlmann P51-CNC2 operators manual
Heidenhain TNC155 operators manual
machine parameters file
The machine has 2 CNC controlled axis (X and Y, feedback via glass scales - Heidenhain LS 903), quill has a digital readout only (via a rotary encoder Heidenhain ROD 456 5000ppr), but has the normal automatic feed modes (coarse and fine, 3 feeds each, min 0,02mm/rev, max 0,30mm/rev), "milling mode" with a fine feed hand wheel on the left side of the spindle housing, and screw thread tapping mode with spindle reversal
After some troubleshooting, mainly caused by me not wiring the 3 phase rotation correctly, and making sure everything on the machine works, it was time to take it apart for cleanup, in the next picture you can see why... X axis slide removed:
