Ceramic Inserts, Cutter Bodies

Seco Tools now 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 8x over standard carbide milling and can machine a range of components for aerospace and power generation turbine segments.

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 1,970fpm to 3,940fpm (600m/min to 1,200m/min) and enable feeds from 0.002" to 0.006" (0.05mm to 0.15mm) per tooth. Combined, these attributes reduce machining cost per workpiece, increase output, and lower energy consumption.

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 32mm to 50mm. Cutters with RN 1207 and RN 1204 inserts for facing are available in diameters from 32mm to 125mm. The imperial range includes diameters 2.0", 2.5" and 3.0".
