    Reverse engineering

    Hi
    I'm trying to figure out how this steel umbrella head button is manufactured (see photo).
    It doesn't look to me like it's been conventionally headed due to the wide diameter of the head in relation to the thin rod.
    The surface suggests that some kind of spinning has been applied, but i haven't been able to match a likely manufacturing process to it yet

    All suggestions are welcome

    Turning (lathe) likely on a swiss screw machine..
    Tell me and I forget. Teach me and I remember. Involve me and I learn.

    Thanks for the answer
    I taught about turning to begin with, but it just seemed like an awfull lot of waste material for a big production (10 mil.+ units). Is turning that the only way to do this?

    What does the part do? Loading, etc.. If it has light duty one could turn the small diameter, punch the large diameter then combine and swage..

    It's for at waterproofed button, so no large force is applied. I'll link a sketch of the system below. The large diameter is 10 mm and the small rod is 2 mm. I'll have an analysis of the steel type soon.

    The steel composition is:
    Si Cr Mn Fe Ni Cu
    0.72 18.52 2.41 68.54 8.16 1.65

    That's very likely to be 303 cu stainless steel, which is perfect for the automatic lathe.
    Thanks Kelly!
