1 / Solution for Steel Turning The leading cermet series for next generation with high wear & chipping resistance in high speed machining High Resistance to Chipping and Thermal Crack Equalized substrate improves chipping resistance and thermal crack resistance. Excellent Surface Finish First-class edge geometries increases surface roughness.

2 / High Performance Cermet Grade for Machining Forged Steel and Sintered Ferrous Steel Materials For high speed and continuous For high feed and interrupted Carbon steels are mostly used when with cermet tools, and machining them involves frequent troubles like crater wear on the rake surface of insert and chipping by built-up edge. That s because carbon steel has low hardness compared to alloy steel and high tensile strength, thus built-up edge is easily created on tools. This new ISO P15 cermetgrade,, was invented for stable turning application at high speed and finishing. Wear resistance and anti chipping have been improved a lot and above all, crater wear on the rake surface of insert would be prevented largely when continuous machining of carbon steel and alloy steel. This will lead to 30% increase of tool life compared to conventional tools along with the test result of 1.6 times increased surface roughness on workpiece. Following, which was proven with its excellent performance at high speed and continuous, was newly released for machining various workpieces such as cold / hot forging steel and sintered ferrous materials. This new grade is specially sintered to uniformed micro grain matrix, thus to improve stability even in tough conditions like highly interrupted workpiece, high feed, heavily vibrating equipment. The test result of surface roughness on workpiece was 1.4 times better with. The leading cermet series / 2500 will make successful result without compromise. Minimum tolerance Stable tool life Advantages Optimal edge design Excellent surface roughness 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
