Does it make a difference,whether a wire guide that is not genuine charmille,is of different quality.I have found guides from other edm supply companys at a considerably less cost.Has anyone switched & had success.
There are certain aftermarket parts I use for my EDM's, but wire guides are not one of them. It's one of the most critical items in terms of accuarcy, so I always use OEM guides. If you do any tapering, this is even more important.
Of course, you could always try a set, and decide for yourself.
