Seco Tools offers Secomax CS300 ceramic inserts and cutter bodies to boost productivity in milling and turning operations with heavy interrupted cuts on nickel-based heat-resistant superalloys (HRSA). The new cutters increase productivity by up to eight times over standard carbide milling and are ideal for machining a range of components for aerospace and power generation turbine segments, according to the company.

CS300 inserts are SiAlON-type ceramics that offer high notch wear resistance, toughness and thermal shock resistance. The inserts provide optimum flank wear resistance at higher cutting speeds ranging from 1,970 to 3,940 feet (600 to 1,200 meters) per minute and enable feeds from 0.002 to 0.006 inches (0.05 to 0.15 mm) per tooth. Combined, these attributes reduce machining cost per workpiece, increase output and lower energy consumption.

The new R220.26 and R217.26 cutter bodies are hardened and nickel-coated for high reliability, reduced chip friction and better resistance to high temperatures. Wedge clamps provide more secure insert locking and feature internal air coolant channels that ensure optimum chip evacuation and heat control. The metric range includes cutter bodies with RP 1204 inserts for facing and pocketing in diameters from 32 to 50 mm. Cutters with RN 1207 and RN 1204 inserts for facing are available in diameters from 32 to 125 mm. The imperial range includes diameters 2.0", 2.5" and 3.0".
