Good morning All:
I just finished up a job making stainless steel micro injectors for a miniature plasma sprayer.
25 parts; the 3 wires on the end in the third picture are 0.015" diameter and 0.150" long welded to a 1/16" diameter tube
The back end with the orbital weld is an 0.093" OD tube with a 0.125" OD tube slipped over it and a 1/16" long step.
This was a super fiddly job but it came out pretty good, so I'm pleased with it.
Positioning the little wires to tack them onto the 1/16" tube was the whole trick, so I made a little jig to hold them in place and clamp them.
Lots of fun fiddling the wires into the jig under the microscope...there's dropped wires EVERYWHERE!
So; what do you think an assembly like this is worth?
- 3 wires tacked at both ends.
- Two annular welds with a positioning tolerance for the tubes of +/- 0.005"
- Overall length 18"
The customer was crying a bit about the price, but they couldn't find anyone else who would take it on in these low quantities, so they kind of had to suck it up.
Now they want a quantity discount because there's MORE!
Cheers
