Hi In copper wire enameling process what type of lubricant is suitable for high speed winding machine? The diameter of our enameled wire is reduced in some areas when it used in high speed winding machine.
You lubricate the wire when you spool it. Most coil winders I've seen are not that careful about tension, wired line, quality of guides and rollers, etc. therefore they often stretch the wire when processing it. If it is correct when you make it and is correct when it enters their coil winder it would seem like their responsibility if it comes out wrong. However if the are consistently stretching the wire you might make it on the high end of the spec so that when they stretch it, it is still within spec. Do they also check resistance before and after winding?
