Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
BTW, I ocassionally come across Spanish-language articles, which I can more or less decipher with my minimal Latin (and emerging French) knowledge. But I always wondered about the easy Spanish name of TBMs - tuneladora[sp?] -, how was that word formed and what does it mean literally?

Tuneladora is a neologism, I believe.

Túnel is a tunnel, obviously.

Tunelar is "to drill tunnels". I am not sure it was standard Spanish (now, post Ruiz-Gallardon, it is!).

Tuneladora is "she who drills tunnels". This is because máquina is of the feminine grammatical gender in Spanish.

By analogy, a drill is taladro or taladradora (a drill bit is not taladro but broca, don't ask me why). Taladrar means to bore a hole. So, TBM does translate as taladradora, but those are hand-held so I suppose it's good they came up with a new term.

Another word for "boring holes" is trepanar, and trépano is the instrument used.

"Hole boring" can also be translated as aburrir a los agujeros, but that's just a snark.

Broca may perhaps relate to "broach" a five sided tapered reamer once used in metal working (now in clockmaking)
