Thanks for the update.
And all points you noted re: exp., re: toolholders, re: work done are 100% positive.
50+ work hours free from HAAS, plus parts !
That IS excellent customer service.
Sometimes, problems are hard. Rare, but it does happen.
The best anyone can hope for is a manufacturer who responds, pays attention, pays for service, is willing to change parts.
It seems, to me, HAAS did all that.
It also seems to me, that You were very justified in asking for all above, and received it.
You are of course right that the manufacturer of a major capital goods product like a CNC lathe must respond -
and from all You said they have done so.
From my POV HAAS did great - with a difficult, unusual, non-recurring problem.
I am sorry You were the one to face this.
Your latest post(s) were also much more detailed, factual, and useful than the first ones.
No offense meant, none.
If You really think HAAS did no do well ...
My personal opinion, based on lots of experience, is that 90%+ of other manufacturers would do much worse.
About 90-95-98% of all new modern machine tools work well.
From all brands. Within their limits/range of course.
Sometimes stuff happens.
Don´t blame HAAS.
Be really happy they were willing to support the product through seemingly intractable problems, with expensive stuff, at their expense.
Imo.
