Precaution and corrective action against wire tangling
When handling wire. “Please do not release wire-end and loosen wire winding.”
When storing wire. “Please do not put spool as shown in Fig.1.”
Precautions when handling EDM wire
(1) When setting spool and wire in the machine
①Please do not detach wire-end label and anti-rust paper when setting spool in the machine.
②Please hold wire (near wire-end label) by your finger when detaching wire-end label.(Fig.2)
③Please do not release wire-end when setting wire in the machine.
(2) When detaching spool from machine.
①Please do not loosen wire winding.
②Please hold wire-end on spool flange by tape.(Fig.3)
(3) When storing wire
①Please rewind anti-rust paper on the spool, because it is necessary for preventing discoloration of wire.
②Please put spool into Hitachi EDM wire carton box.
③If you store wire for a long time, wire straightness become big, therefore we recommend you to use wire as soon as possible.
- *If discoloration and rust happens to wire, it will be a cause of wire breakage.
- *If wire straightness becomes big, it will be a cause of AWF error.
(4) When changing spool and using wire feeding machine(Autoloader)
①Please pay attention to wire tension setting.
Wire tangling check method
If you find loose wire winding or released wire-end, please check the wire winding status and make a corrective action.
①When wire winding become loose or complicated tangling, please hold the wire with your finger and cut tangling area.(Fig.4)
②Unwind wire until wire-end will be single.
③Turn spool and unwind wire slowly as shown in Fig.5.
④In case wire is tangled, you can find a point where wire is crossing.
Wire tangling corrective action
①When you find a point where wire is crossing, please hold it with your finger and push the wire-end to make slack of wire.
②Hold slack of wire with your finger and withdraw wire-end from where wire is crossing.(Fig.6)
(In case wire-end is far from a point where wire is crossing, please cut slack of wire.)
③Please confirm that wire tangling is resolved.
④If tangling is not resolved, please continue the corrective action again.
