bedraEDM – high-tech solutions for spark erosion

Increase your productivity and reduce production costs.

Since the beginnings of spark erosion, we have participated with great success in the continuing development of the technology and the associated improvement in manufacturing processes in the area of mold and tool making. With the functional coatings we’ve developed for EDM wire, enormous increases in the removal rate can be achieved. The resulting increase in productivity is enormous: In tough everyday use, this can lead to 40 percent shorter machine running times. And this does affect production costs. The use of coated wire in spark erosion has the potential to reduce production costs by up to 40 percent.

Further advantages are offered by the patented bedra spool. With its 12-corner design, the spool is effectively secured against rolling away. With this in mind, it’s not surprising that well-known customers in all regions of the world rely on our coated wire electrodes. Every day, bedra high-tech solutions for spark erosion contribute to our customers’ economic success.

blacspark

blacspark with new blac layer is significantly different than typical Gamma class wires. The blac technology is an innovative reconstituted structure that combines a microstructured surface with tiny aggregates of semiconductor materials, which are uniformly distributed and embedded into the surface. As a result, more energy is transferred into the workpiece with each spark, thus increases the amount of material removed with each spark. Combined with the consistency of particle distribution the coating promotes better stability and a higher percentage of cutting pulses to be directed to the workpiece. The result is a faster cutting speed.

    betterbrass ONE

    betterbrass ONE is the revolution for plain brass wires. bedra combines a better continuous casting process with better heat treatment methodologies to create an unparalleled new EDM wire: betterbrass ONE. Our engineers created a plain wire electrode comprised of a completely new alloy that delivers up to 10% faster cutting speeds than traditional brass wire.

    betterbrass ONE is available in 2 wire versions, which differ from each other only in terms of their strength and therefore also in their elongation behavior.

        Storage and changed direction of unwinding of our EDM spools

        The warranty period for all our EDM wires is 12 months after date of manufacturing. Please note the following information on proper storage and the changed direction of unwinding of our EDM spools:

        1. Always store spools in their original packaging in a dry area and in a horizontal way
        The spools are packed in shock, dust and oxidation-proof material to protect the wire from shipping damage and contamination. The wire should be stored in the original packaging until ready for use. This will ensure the highest quality for your EDM applications. The storage of the EDM spools should also always be stored in a horizontal manner to prevent loosening / falling of individual turns of wire and thus disturbances during unwinding. Warranty will lapse in case of improper storage.

        2. Used EDM spools handling procedures
        It is very important to properly secure the loose end of the wire on partially used spools. This will prevent the wire from shifting on the spool and becoming tangled. Improper handling and storage techniques can cause unwinding problems and unnecessary wire breakage. Figures 1 and 2 show two correct ways to secure the loose end of the wire. Figures 3 and 4 show incorrect ways and should definitely be avoided. Partially used spools should be stored in their original packaging material when not in use. This will minimize contamination and shifting of the wire on the spool.

        Figure 4: Do not thread the wire underneathitself so as to overlap.

        3. Changed direction of unwinding of our EDM spools.
        Please note that since December 2018 the direction of unwinding of our EDM wires has been changed, so that the spool label is directed towards the operator on the majority of EDM machines. Further information can be found here.
