Conic Tube

Conic Tube

(OP)
We're triying to find a company willing to make a 316 SS conic pipe 252mm long.
Too see the print please follow this link:

Thanks for any suggestions.

RE: Conic Tube

My suggestion would be to find a swaging company capable of the high diameter/length ratio.  This process is used in making ammunition cartridge casings, medical delivery tubes, and others.  Good luck.

RE: Conic Tube

I have two suggestions to make

1. Using a EDM machine and a pipe with a smaller inner dia. then 3.45 (outer dimensions - as drawing), the wire could give you the taper required and if done slowly can reach the surface finish tolerances

2. Make a conical bar with the dimensions of the inner part.
Then get a bar with a large inner and outer dia then the one required and press it around the conical bar (by using what I think is called a mandrial - not sure of name) to get the require shape.
