OKI EDM Wire 

OKI wire is available in two different tempers: High-tensile and Half-Hard.

The High-tensile wire (OKI type "P") works extremely well on Automatic Wire Threading (AWT) machines and provides a fine surface finish. Some of its unique qualities are straightness, cleanliness, uniformity and packaging.

The Half-hard wire (OKI type "B") is ideal for use on machines that run low tension on the wire and when taper cutting is required

Hitachi EDM Wire 

Electrical discharge machining wire by Hitachi is non-paraffin and manufactured and quality controlled in Japan.

If paraffin wire is used on the W-EDM machine that is specifically calibrated for non-paraffin wire, the characteristics of electrical discharge machining may be adversely affected since the wire travel system will become unstable due to sliding, etc.

Sufficient care must be taken when selecting wire, as cutting seams (called wire marks) are frequently formed, particularly on the cutting surface.

Wire with excessive paraffin or contamination can result in:

  • Wire may easily slip on rollers, etc.

  • Extraneous matter may remain on rollers, etc.

  • Degraded contact detection accuracy and positioning

  • Unstable discharge with respect to weak discharge and a shorter service life of power feed dies

  • Unstable travel of the wire and degraded surface accuracy

  • Trouble in automatic threading and stoppage of the W-EDM machine triggered by guide dies being blocked
