MC Machinery Systems’ ZT hybrid wire for EDMing features a baked-on external zinc layer for increased speed over conventional brass wire, improved accuracy and surface finish, and clean cutting.

According to the company, the zinc coating forms microscopic, precision pockets on the wire’s surface that allow more water to integrate in to the cutting process. This extra water is said to allow for maximum spark energy for faster, more accurate cutting as well as finer finishes.  The added texture also gets water closer to the brass core, allowing for more efficient off-time cooling, minimizing the risk of electrode breakage.

The baking process adheres the outer zinc layer to the wire’s brass base better than conventional coating, the company says, and this strong bond makes the hybrid wire more resistant to flaking, resulting in a cleaner cutting process that can reduce machine tool maintenance and extend its life.

The ZT hybrid wire is available in both hard and soft versions, P2 through P15, and K125- through K250- size spools.
