A Turkish service centre cutting 6 mm 304 stainless plate was getting 1,200 strokes from a D2 shear blade. The fix was M2 HSS at HRC 64, a 0.12 mm chamfer, a TiN coating and a tighter blade gap. 18,000 strokes. The case study walks through the audit, the trial, the result and the ROI.
Definition of burr in industrial cutting: the unwanted projection of material on the cut edge, how it is measured, what causes it, and how to minimise it on slitter, shear and granulator blades.
Plate shear blades see impact, work-hardening substrate and variable stock thickness. The grade, hardness and chamfer choice drive a 10× difference in service life between a mill-spec blade and a generic one. This guide covers carbon steel, stainless, high-strength and abrasion-resistant plate.
