I'm looking into the practicality of adding capability to create custom springs to our R&D department.
The lead time, and cost to iterate is very high using vendors. I am wondering about both the complexity of operating a machine, and the cost of getting one.
We do not need new springs often, but when we do, they always require more iterations than desired, which gives us a longer than desired development time.
2nd question: is there a cheaper method to make springs to high tolerances (but in low numbers). I saw (google, so I can't tell accuracy) a claim that with minimal tooling, a lathe could be used to wind compression springs. How accurately? We have a machine shop, so if true, this woudl be great.
If a spring takes an hour to make, that's fine. right now, we are ordering 1000 to test 1 spring, which then needs a design change...so we re-order, and wait 6-8 weeks for the next one. I'm dying over here.
