Long Lasting Efficiency Machining heat-resistant alloys and stainless steel can present numerous challenges, including rapid insert degradation, deterioration of dimensional accuracy, poor chip control, burrs, increased cutting forces, and excessive heat generation. Kyocera is excited to unveil the PR115S/PR120S series, a comprehensive solution designed to tackle these challenges head-on. With outstanding heat resistance, wear resistance, and stability, this series ensures prolonged tool life and enables stable machining results in both heat-resistant alloys and stainless steel. Under the Surface The PR115S/PR120S series features the MEGACOAT TOUGH HRSA coating, offering exceptional endurance and maximum tool life for machining heat-resistant super alloys (HRSA). The inserts consist of four distinct layers. The first layer utilizes thick-film PVD coating technology, suppressing abrasive wear, and reducing notch damage with its ultra-fine grain structure. The second layer, a TiAlN coating, provides superior oxidation resistance and controls crater wear. The third layer serves as an adhesion layer between the carbide substrate and the main coating layers, enhancing adhesion and scratch resistance. The fourth layer is a unique carbide substrate, formulated specifically for heat-resistant alloy machining, with excellent thermal properties and high thermal conductivity. The PR115S employs a mixed structure of fine and coarse grain carbide for improved heat and wear resistance, while the PR120S utilizes a coarser grain structure for heat resistance and more stability.
