But wouldn't they hold the camera upside down there too?
Shirley their camera's may use gravity - and not a compass?
Actually that tool doesn't look to have a top or bottom.
Must be more for an arbor style horizontal maybe - for slotting? (planing?)

Hello VR6, welcome to the forum.
Would that be a Corrado or Jetta?
Please tell my old friends Derek D. and Tommy H. I said Hi

Good guess. I should have known you get this one easy.
Yup rod pin internal millling cutter. Rough pin dia, undercuts, and cheeking
American GFM crankshaft machine.
A different design in that the crank is held stationary and the mill "orbits" around each pin journal in space.
Being an internal mill with that type cutter's design advantages of less air time between teeth, wicked fast.
Once a star in high production but yet now not the most popular machine in auto as it can't do lots of other things in the same clamp.
In the big boy field on the new stuff I was not allowed to bid a design against Ingersoll and others because I had no representation in China.
That hurt as we had been in automotive crank machining and leading since the late 70's.

Well, that would be a bulky tool for bone screws, so ...
(same principal as whirling)

Yes the same in a most sense but most threads are not 6 inches tall from root to crest and other considerations but yup it is like thread whirling without any side feed.
I only respond as the two, while both internal, are so very different designs.
Yes you are 100% right in the how it works.
This can be done on any 3 axis milling machine with the steps or any form included.

There is no carbide insert ever made that you can not get a rough mold blank for.
The exception maybe is molded chip breakers where the first part will cost you $3000 for the die.
This however does not have that problem.
In the day these would have been pressed by Carboloy in Detroit for Ingersoll so yes that die is long gone but one can still buy preforms from a lot of places.

obviously before my time. he is cutting copper with this cutter. i looked up the carbide info from Ingersoll germany. the carbide substrate is not available in the "L" in their system. they have inventory and have blanks for the "R" which he needs too for the cutter body. he's already asked for inventory in Europe which is where i went looking for inventory
now in the usa market. it's a different story,we have blanks to accommodate his needs but he'd still have to get a quote started with his local tooling rep. there are minimums and a 16 week lead time here in the states
