ISO P/M/K/N/S/H Carbide Turning Grade Classification: Complete Cutting Parameters and Grade Selection Reference Explained
Understanding the ISO Turning Grade Classification System Every machinist who reaches for a turning insert faces the same fundamental question: which carbide grade will deliver the best tool life, surface finish, and productivity for this material? The ISO 513 classification system provides the universal language that answers this question. By sorting workpiece materials into six …
Korloy Turning Grade Technology Explained: NC9025 CVD vs PC5300 and PC9030 PVD Coatings, Architecture and Cutting Parameters
Insert grade selection is often reduced to a single question: which box is cheapest? In practice, the coating system on a turning insert decides whether an edge survives 12 minutes or 30 minutes in the cut, and it dictates the cutting data you can actually run. Korloy’s turning portfolio, built around NC-series CVD grades and …
Kyocera MEGACOAT NANO Coating Technology Explained: PVD Grade Selection, Cutting Parameters, and Applications for Steel and Stainless Steel
Introduction: Why Coating Technology Decides Insert Performance In modern carbide turning, the coating is no longer a protective afterthought — it is the performance ceiling of the entire cutting edge. A well-designed substrate can only express its full toughness and deformation resistance when the coating on top of it delivers low friction, high hot hardness, …
