Each flex beam is .073in wide x .125in thick. .073in x .125in = .00913in^2. There are 9 of them. .00913in^2 x 9 = .0821in^2.How’s does that equal 1/0?
Also it’s only flexing at the first joints.
For sure, use what you got though right? Cycle time is about 14min, but if optimized and higher spindle speed(machine only has 6000rpm) I could see that it down to 4-5 mins. I only have to make 8.Man that took a long time to mill those little slots in gummy copper. Production would be better served by water jet.
The crazy thing is how abrasive that copper is , even on carbide. Gets a little dull, stops throwing chips, packs the flutes and click?For sure, use what you got though right?

Yeah as long as the chips are being ejected, you're golden. 1/16" EM is only running about 100 SFM at 6000 max rpm spindle. .0004" chip load per tooth feed. .02" depth per pass full slot.The crazy thing is how abrasive that copper is , even on carbide.

Love to see how the current is shared with each beam under load with a thermal imager.Each flex beam is .073in wide x .125in thick. .073in x .125in = .00913in^2. There are 9 of them. .00913in^2 x 9 = .0821in^2.
1/0 has a solid diameter of .325in. Divide that by two gives a radius of .163in. Square that and multiply by pie gives us .0830in^2.
Each flex beam is flexing the same amount, you just don't notice it because they stay parallel.
I've never heard of copper belt.copper belt

Unfortunately when you carry a lot of amps through thin laminated copper the ends (bolt area) must be resistance welded together(make solid) or the first layers can bast away. This is what’s done to quality flexible buss barsEnglish is not my first language so maybe i am missing the keyword for it.
They sell thin strip sheet copper in coils. You can choose the thickness and how wide you want it and buy by the meter.
You can find it in aliexpress.
this looks quite niceMy favorite part is when I get to tin copper?View attachment 162485View attachment 162486View attachment 162489
i bet you can sandwich the ends of the laminated bunch with two thicker pieces just at the ends and bolt it all together all it will be fine.Unfortunately when you carry a lot of amps through thin laminated copper the ends (bolt area) must be resistance welded together(make solid) or the first layers can bast away.

You could if the two plates are very flat and you could really tighten it, but most terminals are only 6mm with 4Nm torque. You could probably get away with it, but I’m the guy that never has that kind of luck. If it can go wrong the karma gremlins will find me so I don’t tempt fate.i bet you can sandwich the ends of the laminated bunch with two thicker pieces just at the ends and bolt it all together all it will be fine.
Wow, that's a product I didn't know even existed. I was thinking of regular sheet metal, but I've never seen it anywhere near as thin as you mentioned.English is not my first language so maybe i am missing the keyword for it.

i think is his take on a flexible busbarwhat does this hair comb thing do actually?
