The zinc-coated cobracut® type A electrode was developed in close collaboration with AGIE® and has provided outstanding results on AGIE® machines for years. It’s proven performance is due to its good cutting performance and high accuracy.
In scientific studies it has been shown that the thermophysical properties of zinc (low vaporization temperature means less gap contamination, a high affinity for oxygen and good environmental compatibility) in particular have an advantageous effect on efficient wire cutting. Zinc makes a constant discharge rate possible. Discharge peaks are avoided.
The use of cobracut® type A is especially recommended for cutting carbides and PCDs in order to minimize microcracks and produce the finest finishes.
Coated is not the same as galvanized
All wires are not created equal. There are several ways to coat or
plate EDM wire. bedra’s choice is electro-galvanizing.
This of course is not the least expensive method but the ability to precisely manage electro-plating provides better control over the purity, evenness and cleanliness of the layers.
For years our process has been proven very successful in the manufacture of precision wire electrodes.
Great straightness and accuracy
Due to its great straightness qualities, cobracut® type A is especially suited for machines with automatic wire threaders. In addition, with the diameter accuracy of the wire electrode of ± 1ìm per spool and 1.5ìm from spool to spool, makes it possible to achieve uniform part accuracy and repeatability.
