turning .003 diameter brass wire

[camtd]

I have a long term project I am quoting on. It would be turning a cone point on .003 diameter wire swaging flats further in and then cutting off at .500 long.

Is a screw machine the right machine for the job? If so would one make be better suited?

If not a screw machine then what would do three operations like that?

Thank You

If anything would make those parts, it would be a swiss.... you will need something very small that can get your sfm up enough to do anything...
something like this would be ideal i bet:

I've never even thought about cutting parts that tiny, so i cant offer a whole lot of advice.

What type of volume/year is the production requirements?

Sound pretty "unmakable" on a swiss to me...at least economically.
The problem with the swiss will be the distance between the Collet and Guidebushing. You are "pushing" the material through the guidebushing and at .003 wire, this will be a tremendous up hill fight.

Sounds like you need a rotary transfer or trunnion machine. Maybe even some type of wire or spring forming machine could do this.

That being said, if your volume is low and you made it out of larger material, the above link to MCC's "R" would be a good bet.

Good luck with your quote.

Wow, that is an almost unimaginable task

First off, how much damage is 'swaging' going to impart to the shape of this wire? It's going to be nowhere near as round as it began, so will it have to be rounded again?

As for the cone shape, I think it could be lapped on, rather than turned on with a cutting tool.
