blac technology – a new milestone in EDM, live at EMO 2025
At this year’s EMO Hannover 2025, we are setting a new milestone in the world of EDM (electrical discharge machining) with blac technology (bedra lattice amplified coating). This innovative coating takes EDM productivity to an unprecedented level – without requiring any adjustments to existing cutting technologies.
Innovation with system: blac technology
- A technological leap for maximum efficiency
blac combines a microstructured 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.
- More performance – without compromise
Users benefit from significantly higher cutting performance – both in the main cut and in the first three trim cuts – while maintaining the high level of process reliability they are accustomed to. In addition, blac contributes to energy efficiency in production.
- New possibilities for various applications
Thanks to precise bedra engineering, blac can be applied to different product categories.

Sustainability as an innovation driver
In addition to productivity, a second aspect takes center stage with blac technology: energy efficiency. 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 are 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.”
Experience it live at EMO Hannover 2025
Experience the new blac technology during live presentations at EMO Hannover 2025, the world’s leading trade fair for production technology. From September 22 to 26, 2025, bedra will showcase its expertise in developing and manufacturing high-precision EDM wire solutions for the metalworking industry.
