Transcription

1 / Cermet Solution for High Speed Steel Turning The next generation coated cermet with higher wear and chipping resistance in high speed machining High Resistance to Welding and Oxidation Improved welding and oxidation resistance due to a reaction inhibiting coating film Excellent Surface Finish Preventing chemical reactions between inserts and object materials decreases surface roughness. High Toughness and Wear Resistance High Welding Resistance Excellent Surface Finish

2 / High Performance Coated Cermet Grade for Machining Carbon Steel, Alloy Steel and Sintered Ferrous Alloy For high speed and continuous, the new P15 coated cermet grade, was engineered to provide improved stability in continuous turning applications at high speeds and low depths of cut. Wear resistance has been significantly improved and crater wear(kt) on the rake surface of insert is largely prevented in the continuous machining of carbon steel and alloy steel. Its highly lubricative coating layer shows excellent wear resistance and extended tool life. For high feed and interrupted To expand on the excellent performance of at high speed and continuous of a wide range of steels, was developed for machining forged steels and sintered ferrous alloy at high feed and interrupted., the new P25 coated cermet grade has a specially sintered uniformed micro grain matrix to improve stability even in the toughest machining conditions, like heavy interruptions, high feed or severe vibrations. A lubricative multi-layer coating results in largely prolonged tool life due to excellent wear resistance and toughness. The next generation cermet series / will consistently produce successful result without compromise. Minimum tolerance Stable tool life Optimal edge design Excellent surface finish Advantages Good balance of grade and chip breaker Successful in terms of geometric accuracy and tool life Applicable to carbon steel, alloy steel, bearing steel, sintered ferrous alloy, etc. Comprehensive range covering various workpiece materials 02 KORLOY TECH-NEWS
