Seco’s Secomax CS300 inserts speed HRSA machining

According to Seco Tools, the combination of its new Secomax CS300 ceramic inserts and RN/RP cutter bodies can increase productivity by up to 800% (in comparison with standard milling counterparts) when machining nickel-based heat-resistant super-alloys (HRSAs). Target markets include aerospace and power generation.

CS300 SiALON ceramic inserts are designed to provide high notch wear resistance, toughness and reduce the effects of thermal shock. They also optimise flank wear resistance when higher cutting speeds are employed, and facilitate feeds from 0.05-0.15 mm per tooth.

The company’s new RN/RP cutter bodies are hardened and nickel-coated for increased reliability. Moreover, wedge clamping ensures secure insert locking and optimises chip evacuation, while internal air cooling channels contribute to long tool body life.

Included in the range are cutter bodies with RP 1204 (pocketing) inserts in diameters from 32 to 50 mm. Cutters with RN 1207 and RN 1204 (facing) inserts are available in diameters from 32 to 125 mm.
