Advancements in laser engraving technology to reduce material stress and vibrations are helping to expand and increase the potential for future marketable applications.

The material stress in rolling contact results from the external loading of a bearing under contact pressure as well as from additional stresses of a mechanical, chemical or thermal nature.

Increases the leveling hoop quantity, is eliminated most greatly the material stress, after the leveling, raw material smoothness is more ideal, causes the rate of finished products enhancement.
