Partnership between bedra and Makino

We have expanded our EDM wire range. The new highlights gapstar® ONE and betterbrass as well as topas® H.E.A.T. cover a wide range of applications and convince with high cutting performance.

gapstar® ONE - the new EDM high performance wire with TRIMPAC® technology

Introducing gapstar® ONE, the first wire with bedra’s TRIMPAC® technology. 
gapstar® ONE delivers unparalleled performance, up to 60% faster cutting than brass wire, while maintaining a competitive price. 
TRIMPAC® stands for Triple Impact Sheath - meaning that three major technology components are combined within one coating:
•    Thin oxidic films
•    an optimally elevated zinc content 
•    and a special surface structure
The new wire generation delivers significantly faster cutting speed than older generation wires such as cobracut, broncocut, and topas. gapstar® ONE raises your throughput up to 60% versus brass wire. When you take into account two important elements of staying competitive: wire consumption and hourly machine rate- your production cost will be lowered by more than 37%!

gapstar® ONE is available in 3 wire versions, which differ from each other only in terms of their strength and therefore also in their elongation behavior.

betterbrass - 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. 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.Faster eroding. Less wire consumption. Lower wire costs. This is exactly what you get with betterbrass - the revolution for plain brass wires.

This electrode utilizes innovative and efficient production processes to deliver performance never before seen in a traditional brass wire.

  • Extremely reliable performance
  • Plug-and-Play on all machine types
  • Cuts up to 10% faster than traditional brass wire
