Straightness and wave measurement

TBK also offers straightness measuring equipment for rounds, tubes, sections, and rails. This is typically done after straightening or finishing. Rails are one of the most demanding sections with regard to waviness and represent a good example of the contact-free, continuous measuring system PROwave.

Measurement principle
Ultra-precise laser sensor images are taken of the head contour of rails over the whole rail length, and the waviness of the surface on the exact center line of the head and in a horizontal direction 14 mm below on the side of the head is determined. The display forms, derived from traditional specimen measurements, are expanded to include a graphic representation of the real surface over the section length, providing direct information on the current straightening process. The recognition of trends enables reliable production within tolerance limits and proactive corrections on the finishing line.
