the Heidenreich 540 lathe was produced in Hamburg till 1987. Then they closed lathe production and only built Makino machines. In Moelln is the H&H foundry till now.
The film you mentioned is really interesting. There is also a film from 2002, who shows the devolopment of H&H and tells the story of 3 former employees, who worked there at different times. This film was produced by Jürgen Kinter und Geschichtswerkstatt Hamburg Barmbek. If you only speak english or french it is also hard to understand.
Would it be possible for you to send me your contact information? We are looking for the "Orange Book" that seems to be the holy grail for servicing the Dialog 11 control. We have another issue but we have a good person working on the machine. We need to find a source of information.
Do you still have that information on the FP33 - even if it is in german ?
I would appreciate if you email it to me to [email protected]
(Else, could you send a photocopy to Geneva, Switzerland ?).
Altough swiss, I live in Perú and it's quite difficult to obtain techhnical info.
Best regards, and thanks in advance,
