I forgot to add the slot length is 28mm (1.10")
and slot deep is 1.00 mm (0.039")
Let me describe a little further
(1) The slit corner is important. The slit edge and the slit straightness from front to back is extremely important.
As the electrode burns the slit, it will create a funnel...
The challenge is applied the accuracy to both part (or feature) location and size. The EDM electrode is .007" width.
Electrode size / location placement fixture is already out of range for this application.
It looks like any optical component fabrication will have some technology transfer...
oops...we are sourcing hyperbola rod using invar (38% over steel). There is an ion ejection slot of .28mm (.011") width with +/-.02 mm, 20 micron (which is .0008") . The slot is being made via EDM. The slot size accuracy is less than .001" (NOT .001"). It can not have any radius at the corner...
anyone know how to measure and do micron / submicron machining.
If you know any shop, let me know. Our company works with a german company doing highly precision work. But our company need to develop US based supplier technical know how for our component supplier chain
Please help !!
we are...
