09/06/2020 – Spark erosion
Berkenhoff has developed a new brass wire
The wire manufacturer Berkenhoff has applied for a patent for a new technology in the field of bare brass wires with “betterbrass”.
The wire achieves significantly higher cutting performance than all other brass wires for spark erosion manufactured by Berkenhoff under the umbrella brand bedra – while at the same time offering high cutting precision.
Bedra has made targeted further developments in its key technologies of continuous casting and heat treatment. Through this, the engineers have succeeded in generating a wire electrode with a new type of alloy, thus increasing performance. In doing so, Berkenhoff uses its competitive advantage of its in-house foundry, which is what makes further development in this area possible in the first place. The innovative alloy and casting technology provide “betterbrass” with the basis for high process performance and stability right from the original forming stage.
A specially developed heat treatment controls the development of performance-enhancing elements. This allows the cutting performance to be increased by 10%. This means that less wire is used, material is saved and therefore costs are reduced. Reliability and precision remain the same. This electrode combines a lean production process with a previously unattained performance characteristic:
– Absolute process reliability
– Plug-and-Play on all machine types
– 10% more cutting capacity
The wire type betterbrass ONE.9 is a brass wire for all EDM machines and standard applications. It has a tensile strength of 900MPa and an elongation of 1%. Wires of the betterbrass ONE type are supplied on spools K160, K200, K250, K355, P5, P10 and P15, with a wire diameter of 0.20mm, 0.25mm or 0.30mm.
