Hi Dave.
I’m writing from Portugal.
The “Optimum range” as You wrote in reality is made in Chine like many others.
There is, however, a difference as they say: the machines are made under control
and guidance of German engineers.
I have an Optimum BF20 Vario milling machine for almost three years and, apart
some initial electronic problems (the control box was replaced three times)I have
no problems at all. I must say I am quite satisfied with this machine.
In the following URL You can download the full Optimum/Quantum catalog
and within it, at page 2, You’ll see the following text:
Production
Since 2003 OPTIMUM® produces a large part of its metal processing machines in
its proper factory at the Chinese Yangzhou with a German production manager and quality management representative.
Development, design and quality management mainly take place in Germany.
Best regards
