I operate Agie Innovation 3 die sinking machine and I have a problem eroding pockets (aprox. 25x55mm) for area inserts (into main insert).
Pockets are blind and 150-200mm deep and must be absolute square and in tolerance +0.01/+0.02mm.
I have problem with machine stopping becuse of short/contact and erosion times are huge (30hours/pocket). I am using Tokai Carbon graphite HK15
and 2 electrodes with undersize -0.15/side and -0.07/side (I want to have sharp edges).
What can I improve and many thanks for your support.
