As to Japan making better machine tools than the U.S. I'd have to call BULL SH*T on that.
MOORE JIG BORES, MONARCH LATHES, PRATT WHITNEY, BROWN & SHARPE , AMERICAN, HENDAY, RIVETT, AXLESON, and to many more to name, Mills, Grinders, Lathes , ect, ect.
The MOORE JIG BORE was GUARANTEED for TEN years..greatest error in any inch ....30 Millionths, Greatest error in 18"... 90 Millionths.
Monarch's 10EE were GUARANTEED ..Spindle accuracy both Radial & Axial run out -.000030 .
Most of the big lathes made in the early 40's were run HARD 24/7 earlier in their life and are still around nearly ....70 years later.
Though it would be hard for me to prove I doubt very much if Japan will be able to say the same.

Hal, I don't know anything about your background but most of the machine tool companies you mention, I have been in their factories. I have been in the homes of many of the CEO's.
The Moore Jig borer would not be a pimple on the butt of a CIP. All conventional jig borers position by standard rods. All their accuracy is Dependant on the accuracy of those standard rods.
Monarch EE's, I've bought several and had several rebuilt at Monarch/Sydney. I remember the last two I had rebuilt, cost was about $65,000 or so and a spindle bearing pac was about $18,000 or so.
Now then, just go to a Mazak plant and see what they have as a spindle bearing pac that cost $45,000 and operate at over 15,000PRM!! Yes, I know Terry Yamazaki too. (ya-MAZAK-i) He has a Ming Dynasty tea pot in his foyer that is insured for $2,000,000. I've seen it up close.
Monarch/Sydney, Monarch/Cortland, American Tool, Cincinnati-Gilbert, Cincinnati-Milacron, Cincinnati-Greeves, Van Norman, Kearney & Trecker (been to Ted Treckers house too), Giddings & Lewis, Mazak, Hitachi-Seiki, Pratt & Whitney, King, Bullard, DeVleig, Lodge & Shipley, Jones & Lamson, Gisholt, Edlund Drill, Grey Planer, ad nauseous. I Been there dude!!! Don't tell me Bull Sh*t when it comes to machine tools!!!
