Wire won't Thread out of Pipe End

M. Roberts said:

What make machine is it? My first guess would be a plugged water/wire seperator...happens on my Sodick sometimes...

So I am about 75% sure that the long tube the wire enters after clearing the lower roller is at fault. I pulled it out and it is in pretty rough shape I am guessing it hasn't been touched since we got the machine. Wire seems to be coiling up inside and getting itself stuck due to debris and mainly poor condition of the pipe itself. If this is what your referring to Jim then you might be spot on. Is it best to just outright order a new one? I assume it'll be around $200-$300 to get a new one, or is there some way to work around it? I went ahead and tried cleaning it with a brush attached to some wire and just dragged it through, though it didn't seem to help much if at all.

Thanks,

Hey all,

We have MV4800 WEDM that is having a problem threading that I've never encountered before. The wire threads on its own past all the diamond guides, past the lower roller, and into the long tube that takes it back to the wire chopper. However, just before it can get out of that tube and into the pipe end block(the clear block that then threads it into the two rollers) it gets stuck. It feels like there is a wall preventing it from getting any further. I've tried manually threading it by hand, automatic threading, threading with and without wire collect on but to no avail so far. I've taken apart the wire chopper and cleaned everything out, took part of the ending of the tube out and checked to see if there was a blockage in the pipe(there wasn't one) verified that all the components are in good condition/where they need to be everything looked normal even compared it to our other MV4800 that is currently working, nothing seems out of place.

I manually threaded some wire through till I got to whatever is stopping the wire from threading and pulled the wire out and measured the wire. From the top of the bottom flush cup to whatever is blocking my wire it is give or take about 8ft and 3in.(+/- 1 in. maybe since it was kind of a pain in the ass to measure.) If anyone has had this problem before or anyone has any ideas please let me know I am not quite sure what to do next.

Thanks,

Had the same issue not too long ago on my Sodick AQ750LH. Took the clear resin box off, soaked it in CLR overnight and then rinsed it real good the next day before reinstalling it. No more issues. Also, make sure "wire run" is on when manually threading. I tend to have my guide open, water on along with wire run on when doing manual threading through the lower head.
