Latest Patents

Ishii's latest patents include a cutting tool and a surface-coated member. The cutting tool features a body with a rake face, flank face, and cutting edge, designed to enhance the efficiency of cutting operations. The rake face is positioned on the top surface of the body, while the flank face is located on the side surface. A key aspect of this invention is the region A, which is near the cutting edge and has a maximum height of the roughness profile Rz(A) ranging from 0.5 to 1.0 µm, with a negative skewness Rsk(A).

The surface-coated member is designed to improve durability and performance. It consists of a base body made from materials such as cemented carbide or cermet, coated with a hard layer that includes at least one TiCN layer and an AlO layer. The TiCN layer is characterized by stringer-like crystals that grow perpendicularly to the base body, ensuring excellent breakage resistance and high wear resistance during cutting operations.
