Definition of surface roughness (Ra) in industrial blade measurement: the arithmetic average of the absolute deviations of the surface profile from the mean, and the typical Ra targets for slitter and shear blades.
Definition of swarf in industrial cutting: the chips and particles generated by the cut, and how swarf handling affects knife life and line cleanliness.
Definition of ta-C (tetrahedral amorphous carbon) PVD coating for industrial blades: a harder, lower-friction variant of DLC, ideal for aluminium foil and medical cutting.
Definition of thermal fatigue in industrial cutting: failure by repeated thermal cycling at the edge, common on high-speed tissue and film slitting without active cooling.
Definition of TiAlN (Titanium Aluminium Nitride) PVD coating for industrial blades: a violet-black high-temperature coating for hot-work and foil slitting applications.
Definition of TiCN (Titanium Carbonitride) PVD coating for industrial blades: a harder and more wear-resistant variant of TiN, ideal for abrasive substrates.
