Berkenhoff has built on the pioneering technologies of its previous high-performance wire generations such as cobracut, topas and boline, to develop a new electrode and coating technology in Trimpac, featuring a zinc-enhanced coating.
“We are extremely excited about this new wire and how it can benefit the UK market,” comments Brendan Kelly, technical sales engineer at Erodex UK. “As well as dramatically increasing speeds by 40% - 60% compared to standard brass wire and typically 10%+ compared to our Boline H product, users will also see a significant increase in feed rates.
“This increase is achieved in both rough and skim cuts, without necessarily adjusting current settings. A further benefit is the reduced wear of wire guides and power contacts, minimising downtime and ultimately cost. Thanks to the newly developed Trimpac coating, an accuracy to Ra 0.25µm can be expected, as well as increased stiffness and excellent straightness for auto threading.”
From stock, gapstar One will be available in 900N and 500N tensile strengths. It is compatible with all brands of machines and is available in most spool sizes. The wire has been received extremely positively in early customer trials.
“As with its predecessors, whilst gapstar One is more expensive than brass wire to purchase, dramatically increased wire speeds and its ability to achieve the desired surface finish means more throughput and increased efficiencies. Users can expect savings of up to 40% when compared with the topas Plus H 2.0 range for example,” Mr Kelly explains.
He concludes: “Simply using gapstar One will enable these benefits to be realised, but we are also able to work with customers to optimise their machine settings to generate even better results.”
Erodex UK’s strong working relationship with bedra (Berkenhoff) and vast experience within the EDM industry has cemented the company’s position as a leading authority in the UK for all things EDM wire.
