US source of Panzerholtz?

Why not order to spec from BDR?

It is fairly miserable to CNC, as well. A bit eating monstrosity it is... with a very narrow range of functional feed and rpm ranges. Delrin is similarly miserable to CNC.

One of the worst combinations, it is: Your sharpest finest bits, with the highest level of bit wear, in the most difficult to achieve ’quality result’ cutting set up. Instantaneous flow of the moment.. feed rate and rpm, stepover, etc, all become critical in the given moment --and the range is small. So you have to change everything in the cutting program to reflect this. Mastering a quality CNC’d shape in panzerholz is an achievement.

Dear chakster, How can different name change the properties
of whatever material? Each language has different names for,
say, the same objects. That is why logician state that names 
have only referential function. Then there is the logical rule that
names miss predicative function. That is to say that names don't
say anything about is bearer. Sorry but I need  for 66 times , as
you pointed out, use as example Vienna. Whatever is true about
Vienna is also true about Wien, Wenen , Bec, etc.  names.
This is called ''substitution  salva veritate''. Each of those names 
refer to the same city. 

@nandric it's a German name for the material as far as i know, in Russia nobody use such name, but we have something similar under completely different name, unfortunately the difference is not like Vienna and Wien (i love that city BTW). It is similar to bakelite plywood ?

Dear chakster, There are to many objects in our universe. We don't
have names for each of them. So we invented the so called ''descriptive names''. Say ''iron horse'' for the first seen locomotive. 
Those are like ''x +2''. We know that this is about numbers but we
can't know which one. We need some name in '' x position'' in
order to know which number is meant. Those are called ''functional
expressions'' because they entail an  variable (x) . So such expressions are not complete. They need a name in place of the
variable x to get determinate meaning. ''The teacher of Alexander'',
''the author of Das Kapital'' , etc. Those who know that Aristoteles
was teacher of Alexander will ''feel in the gape'' and those who
know that Marx wrote the mentioned book will complete the
descriptive name with the ''argument'' Marx. 
So you are referring to ''descriptive names'' which entail only
a part of an  predicate. The other part needs  addition with 
other part of predicate to be complete. There is, so to speak,
one missing part. Aka with ''iron horse'' we in Russia mean an
locomotive (gin).
