摘要： A method for forming a stand-alone wafer or a coating on a substrate uses a composite of cubic boron nitride (cBN) particles and other materials, such as nitrides, carbides, carbonitrides, borides, oxides, and metallic phase materials. The wafer or coating may be formed of a thickness up to about 1000 microns for improved wear life. The density of material within the wafer or coating may be varied according to desired parameters, and a gradient of particle sizes for the cBN may be presented across the thickness of the material.

摘要： A cutting insert enables a reduction in cutting resistance and stable cutting process. The insert includes a chip breaker groove formed inside corner cutting edges and a raised portion. The raised portion includes a top surface, a front raised surface, and side raised surfaces. The top surface intersects the front raised surface and each of the side raised surfaces. A first intersecting portion at which the front raised surface and the top surface intersect with each other extends linearly. A second intersecting portion at which each of the side raised surfaces and the top surface intersect with each other extends from a corresponding one of opposite sides of the first intersecting portion so that a distance from the corresponding side cutting edge increases gradually with a distance from the corner cutting edge. The front raised surface and the side raised surfaces are curved convexly outward.

摘要： The invention relates to an eight-edged rotatable and reversible cutting insert having two opposite, substantially square base surfaces which are twisted relative to one another about a central axis running perpendicularly to said base surfaces, and having four identical side surfaces. A main lip is formed between each base surface and each side surface and extends only over part of the length of the side surface. Each side surface has two diagonally opposite corner edges which are of circular or curved design and form a secondary lip adjacent to the respective main lip. In addition, each side surface has two chip pockets which are drawn into the side surface and which, starting from the respective corner edge, extend along the main lip assigned to said corner edge up to a rear chip pocket end.
