??? A gantry machine is not a planer. Nor is a planer mill. If there's new planers being made, I musta missed 'em.
I had a long and sordid history with aerospace gantry mills when I was in the machine tool rebuild biz. The Onsrud we did was good. Cincinnatis were prime, but I never got to work on one. The worst ones were Shin Nippon Koki. (SNK) Junk when they were brand new.
No, I lie. The worst ones were the first rebuild project I was ever put in charge of. Two 70' Farnhams. Gantry machines made during the Korean War by a company which was actually a specialist in woodworking machinery. Took me almost two years to get them sorted out. The fact that my predecessor had sold the Air Force on some insanely stupid modifications didn't help.

Kinda OT ain't we! From bench lathes to machines bigger than a railroad car!
