Sadly as in "sadly it rarely says Made in Germany"!

Or Made in USA

Used to be, hopefully still is - hard to tell with so much stuff being made in China yet getting advertised as made in XYZ.

If you cut to the chase you really have no idea where it's made .

Out sourcing is world wide on just about everything no matter what it is .I made my living for over 40 years of a 50 year stint working on high speed metal working machinery in the automotive business .I've worked with machine vendors from all over the world .One company ABB from Switzerland now makes robotics in China .That's just one example of many .

This is that Tungaloy mill head at work, it is rated to be capable of taking a 7+mm deep bite in one pass processing steel and cast iron, and I admit in mild steel it is very capable.

1000+ countersunk threaded blind holes, I believe one tap broke (the hole most likely had chips in it bottoming the tap out!) and two or three got replaced preemptively.

Highest pureness copper, beautiful metal.
It is a reusable mold for pouring "test coin" casts.

ISO 12.9 grade bolt steel, my love/hate relationship!
Amazing steel alloy.

 

[Wilhelm]

Identical Solid-Carbide mill bits.
The left one was ran dry (no cooling!) in serial production grey cast iron (pig iron), the right one was ran in 12.9 grade bolt steel at lower rpm's, feeds and much shorter runtime WITH maxed out liquid cooling.

Hint: The right one is trashed!

 

[Wilhelm]

Identical Solid-Carbide mill bit as mentioned above in mild steel alloy, amazing performance, minimal cooling applied with a squirt bottle (info corrected!).

Except the 6 holes which have been drilled, everything else has been milled.

 

[Wilhelm]

And this is what it looks like almost done.

304 Stainless air knife I made for a raspberry freezing tunnel to remove snow from the belt as it exits the tunnel. -15F degrees while running product inside. -39F is as cold as I can get it running empty.
