Definition of CrN (Chromium Nitride) PVD coating for industrial blades: a corrosion-resistant silver-grey coating, the standard for food-contact and wet applications.

Definition of dead zone in industrial slitting: the area immediately around the cut where the substrate is unsupported and can wrinkle, tear, or lift.

Definition of DLC (Diamond-Like Carbon) PVD coating for industrial blades: the lowest-friction coating available, eliminates built-up edge on stainless, aluminium and sticky polymers.

Definition of dressing in industrial blade grinding: the process of re-sharpening or re-shaping a grinding wheel to expose fresh abrasive and restore geometry.

Definition of edge rollover in industrial cutting: deformation of the edge where the substrate pushes the steel over instead of cutting it, common on a too-soft knife or a too-sharp edge.

Definition of fatigue wear in industrial cutting: loss of knife material by sub-surface crack propagation under repeated thermal-mechanical cycling, common on high-speed lines.
