At last month’s EMO 2025 exhibition in Germany, Bedra says it set a new milestone in the world of EDM with Blac technology (Bedra lattice amplified coating). According to Bedra, this innovative coating takes EDM productivity to an unprecedented level – without requiring any adjustments to existing cutting technologies.

Blac combines a micro-structured surface with a lattice-like embedding of semiconductive materials. The result: each spark discharge is coupled into the workpiece more efficiently, allowing a greater portion of the available energy to be converted into material removal.
 

Users benefit from higher cutting performance – both in the main cut and in the first three trim cuts – while maintaining high levels of process. In addition, Blac contributes to energy efficiency in production. By making better use of spark discharges, users consume noticeably less electricity per finished workpiece – a tangible contribution to CO₂ reduction and sustainability strategies in industrial manufacturing.

“With Blac technology, we’re not only delivering a new coating generation, but making a technological statement for greater efficiency in production,” says Dr Tobias Nöthe, CTO. “Anyone who wants to future-proof their manufacturing will not be able to ignore this technology.”

Launched now is Topas Blac G and Blacspark H, representing the first product innovations based on Bedra’s Blac technology. Both products are designed to translate the advantages of the new coating into measurable benefits in everyday use.

For more than four decades, Bedra says it has been shaping the development of wire EDM and setting standards in precision and performance. Its innovations have continuously advanced the technology, making processes more reliable and productive for customers worldwide.
