Hello and good morning to everyone.
I am new in edm sinking and i have a problem that i
Wanted to ask if anyone else has experienced also.
Many times i try to make calibrated holes, for
Example d3,d5.... That have tolerance 0.01.
The problem is that many times the holes becomes
Reverse conical(i dont know if i explain it correctly).
It comes out like that /\.
So if i try to make a d5 i try to be 5 on top and 5.01
At the bottom.on deeper holes though its more than 0.01.
Can anyone explain why this happens and how can i make a correct hole.
I tried external flushing/ spindle flushing.
I tried electrodes that are bought or i made myself in turning machine
It happens in through holes and blind ones.
In through holes most of the time its like a barrel.
I mean that its 5 on top.5.01 at the middle.5 at the bottom.
Any ideas will be appreciated.
