I'd appreciate it if some one could give us some EDM data.We're going to make some cavities in aluminum, .75x.375, Depth 2.5 inches.
We are completely new to this.
Machine is a Hurco EDM.
We need:
On Time
Off Time
Amp.
Work time
Up Time
Voltage
to get it done as fast and as accurate as possible.
Do you have to do a rough run before finishing the hole?
Thanks in advance.:withstupi
I would rough then semi finish and finish use negitive polarity... is machine cnc/ what type of control...the negitive polarity will burn very fast but will wear trodes fast....
Thanks.
It's a TRM-39, manual in X ,Y and the control is a Futaba.
How about these values?
On Time-050
Off Time-015
Amp.-15.0
Work time-05
Up Time-15
Voltage-80
It took me 25 min. to get a .5 depth.
With predrilled holes,16 min.
Good or Bad?
