Seco Duratomic CVD Coating Technology Explained: Al2O3 Layer Architecture, Grade Selection, and Steel Turning Parameters
CVD (Chemical Vapor Deposition) coatings have been the workhorse of steel turning for decades, but the deposition of aluminum oxide (Al2O3) layers has long presented metallurgical challenges. Seco Tools’ Duratomic technology represents a fundamental shift in how these layers are engineered—not merely deposited—at the atomic level. This article breaks down the Duratomic coating architecture, explains …
Inconel 718 Milling Best Practices: Tool Selection, Cutting Parameters, and Troubleshooting for ISO S Superalloys
Introduction: The Inconel 718 Machining Challenge Inconel 718 (UNS N07718) is a nickel-based superalloy that has become the material of choice for high-temperature, high-stress applications across aerospace, power generation, and chemical processing industries. Its exceptional mechanical strength at temperatures exceeding 700°C, combined with outstanding oxidation and corrosion resistance, makes it indispensable for turbine discs, combustion …
Iscar vs Seco Stainless Steel Turning Inserts: Grade Technology, Coatings, and Cutting Parameters Compared
Introduction: Why Stainless Steel Turning Demands Specialized Grades Stainless steel—particularly austenitic grades like AISI 304 and 316L—remains one of the most challenging workpiece materials in CNC turning. Its combination of low thermal conductivity, high work-hardening tendency, and built-up edge (BUE) susceptibility places extreme demands on cutting tool grades. Heat concentrates at the cutting edge instead …
