industrial blade failure analysis

  Industrial Blade Failure Analysis: Diagnosing Chipping, Cracking and Premature Wear   When a blade fails early, the first explanation is almost always the same: the steel was not hard enough. Acting on that answer is how a plant ends up replacing the same set twice in one season. Chipping, cracking, accelerated wear and deformation are four different damage mechanisms with four different causes and for two of them, raising hardness makes the failure arrive sooner, not later. This guide works backwards from the damage: how to read a failed edge, which measurable parameters to check before you blame the material, and where the line sits between regrinding and replacement.   Start with the damage, not the steel. Classify the failure — chipped, cracked, worn or...
