Hardened Steel Hard Turning Tool Selection Guide: CBN and Ceramic Insert Recommendations for HRC 55-65
Introduction to Hard Turning of Hardened Steel Hard turning replaces cylindrical grinding for finishing hardened steel components in the 55 to 65 HRC range, delivering shorter cycle times, greater flexibility, and comparable surface integrity when the process is controlled correctly. The technology is widely applied in automotive gearing, bearing races, hydraulic valves, and transmission shafts …
Iscar vs Vargus Threading Inserts Compared: ISO Metric Thread Turning Performance and Grade Selection
Introduction: Why Threading Insert Selection Matters Thread turning is one of the most demanding metal cutting operations. Unlike conventional turning, the insert follows a helical path with a continuously varying depth of cut, and the cutting edge must form a precise profile while managing chip evacuation across a narrow groove. For CNC machine shops producing …
