Hard-coated brake discs become a hot topic

Alongside tire wear and the combustion of fossil fuels, brake abrasion contributes to the high particulate pollution caused by vehicles with combustion engines and electric or hybrid drives. The automotive industry needs innovative technical solutions to reduce this contamination.

A series process, in which. laser cladding provides brake discs with high-quality corrosion protection and a wear-resistant hard coating, is now available to reduce brake-related particulate emissions is available. This innovative hard coating process leads to high-quality anti-corrosion and wear-resistance.

Coating and grinding process

JUNKER offers brake disc coating and grinding innovations, allowing optimum friction pairing and reduced particulate emissions. During the grinding process, the brake disc is simultaneously ground on its parallel sides with two opposing grinding wheels. This state-of-the-art manufacturing process achieves perfect flatness and precise axial runout, and the coating thickness deviation is significantly reduced.

Maximum benefit for customers is achieved with the world’s first series-produced grinding machine JUDISC, a machine specially developed to grind hard-coated brake discs.
