Silent Cut

Plasma cutting with reduced sound pressure level

Kjellberg Diagramm Schalldruckpegel Vergleich

Due to the high energy density and flow velocity during high-quality plasma cutting the sound level can amount to more than 100 dB(A) depending on the cutting task. With Silent Cut, Kjellberg Finsterwalde offers a solution to reduce the noise exposure significantly which is perceived as disturbing particularly in the upper frequency range. Silent Cut thus contributes to decrease one of the most common dangers in the working environment.

Silent Cut reduces the sound pressure level by up to 15 dB (A) during plasma cutting of mild steels with a material thickness between 4 and 30 mm in the current range from 60 to maximum 170 A. A reduction of the sound level by 10 decibels is already perceived by human hearing as a halving of the loudness. Thus, Silent Cut makes an important contribution to health and safety at work – with high cut quality comparable to the Contour Cut technology.

Silent Cut is available as standard for the machines of the HiFocus neo, Smart Focus and Q series. In order to benefit from Silent Cut only the nozzles in the plasma torch have to be replaced. All necessary cutting parametres can be found in the Silent Cut database.
