I'm pretty new at this forum, am on another forum more in the past for cnc milling.
I'm having trouble with my wire edm having slow cutting rates and a servo that wants to keep ramping the cutting speed and always just breaks the wire. I'm able to get like 1.1 to 1.5 in^2/hr by limiting the speed with the S parameter so the wire wont break.
have tried stratified and half hard brass, similar results in terms of cutting rates.
I'm not able to seal the nozzles to my parts due to the nature of the parts. The robofil 510 is supposed to cut at 20+ in^2/hr though (i assume with sealed nozzles and ideal conditions). Something is up with this machine, any experience out there to suggest what to look at?
the machine contacts upper and lower to the table measure 220ohm, the table to machine gnd measures about 60kohm. the water filters are pretty new / all 10 running, the upper head is in very clean condition I rebuilt it a few times already. The lower head has new pinch rollers. contact wetting is good in the upper head.
It seems that when the machine runs the %ST / protections strategy up higher like at 70%+ I dont get wire breakage right away and can cut faster, but as soon as that decreases the %machin. just keeps ramping and goes from 1 or 2 up to 12 to 15 and then the wire just breaks. Seems like a servo problem or .tec problem? maybe one of my boards is on its way out?
