摘要： Provided is a cutting tool in which one end side of a protruding cutting edge is sharpened while wear resistance is improved. The cutting tool of the present invention includes an end surface, a peripheral side surface that intersects the end surface, and a cutting edge in an intersecting ridgeline portion between the end surface and the peripheral side surface. When first and second points (A and B) are set on the cutting edge, the first point (A) protrudes further toward an outer side of the cutting tool than the second point (B). The cutting tool has a coating film on its surface. The cutting edge has a portion in which the thickness of the coating film gradually increases toward the second point (B) from the first point (A).

摘要： A solid-lubricated metal cutter and processing method relates to the technical field of metal cutters. A surface texture morphology is worked out on a metal cutter, a solid lubricant is filled into the surface texture morphology, and a convex dam is arranged on the cutter surface on which surface texture morphology is located at a chip flow side. The surface texture morphology has micro-pit and micro-boss features, and can exert antifriction effect of a solid lubricant and anti-adhesion effect of micro-protrusions. The convex dam is arranged at an end of the micro-texture region away from the cutting blade, so that a part of the solid lubricant flows back to the texture region and thereby the utilization efficiency and retentiveness of the solid lubricant are improved.

摘要： A turning insert includes a top surface, an opposite bottom surface, side surfaces connecting the top surface and the bottom surface and two opposite nose portions. Each nose portion includes a convex nose cutting edge, a first cutting edge and a second cutting edge. The convex nose cutting edge connects the first and second cutting edges. A bisector extends equidistantly from the first and second cutting edges. In a top view the first and second cutting edges on the same nose portion form a nose angle (α) of 70-85° relative to each other. Each nose portion includes a third convex cutting edge adjacent to the first cutting edge and a fourth cutting edge adjacent to the third cutting edge. In a top view the fourth cutting edge forms an angle (β) of 0-34° relative to the bisector.

摘要： The present invention relates to a cutting insert having a cutting edge which is provided with a corner section that forms a convex arc shape when seen in a planar view from the direction facing the rake face and a pair of linear sections that are in contact with the corner section at the both ends thereof. The cutting edge is provided with a first region along the corner section, a second region along the linear section and a third region positioned between them, and a cross-sectional area of the insert main body on a cross-section orthogonal to the cutting edge in a range of width which is a radius R (mm) of the corner section is made largest in the third region, smallest in second region and between them in the first region in terms of size.

摘要： A double-sided, indexable, polygonal turning insert includes a plurality of corners, a peripheral clearance surface, and identical upper and under sides. Along the upper side and underside, primary cutting edges, which individually include a nose edge situated in a corner and two main edges, converge toward the same and transform into auxiliary cutting edges, which separate each pair of primary cutting edges along one and the same side. Chip-directing guide surfaces are placed inside the chip surfaces of the cutting edges. The primary cutting edge has a generally positive cutting geometry such that a wedge angle of the cutting edge between the chip surface and the clearance surface is acute in arbitrary sections along the nose edge, as well as along the two main edges. In such a way, the primary cutting edge produces chips that can be guided in a careful, although distinct, way by the guide surfaces.
