Abstract: Reaming tool includes a head and one or more detachable cutting inserts fixed in seats. The seat includes radial, tangential and axial support surfaces, while the cutting insert has a mirror-symmetrical polyhedron shape comprising six limiting surfaces, viz. two chip surfaces and four clearance surfaces, a number of alternately usable identical cutting edges formed in the transitions between the chip and clearance surfaces. The cutting insert has a rhombic cross-sectional shape with four clearance surfaces, which meet each other in pairs at obtuse angles in two opposite corners, and which, along each individual chip surface, form two cutting edges alternately usable by indexing the cutting insert. The seat additionally includes a slope surface forming an obtuse angle with the radial support surface, suitably of the same magnitude as the obtuse angle between the clearance surfaces of the cutting insert. Tool head and reaming insert for the tool are disclosed.

Abstract: A gyratory crusher outer crushing shell. The outer crushing shell comprises an upper contact surface region that is divided into a plurality of elongate circumferentially extending shoulders. The shoulders are separated by recessed gap regions adapted to accommodate a suitable backing material to structurally reinforce the shell. A channel extends circumferentially around the shell in the outward facing surface to axially separate the upper contact surface region from a lower contact surface region. The channel is also adapted to accommodate the backing material.

Abstract: The present disclosure relates to a polygonal turning insert having primary cutting edges, which individually include a nose edge and two main edges, which converge toward the same. Behind the nose edge, chip-directing guide surfaces are formed, on one hand, with a breast surface included in a knob situated behind the nose edge along a bisector between the main edges, and, on the other hand, with a pair of flank surfaces included in a land there behind. At a distance behind the knob, there is formed a second breast surface, the upper part of which is situated on a higher level than the upper part of the first breast surface. In such a way, it is guaranteed that thin chips, which tend to pass or jump over the first breast surface without being affected by the same, will impinge on the second, higher breast surface and be subjected to guiding by the same.

Abstract: 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.

Abstract: A drill of the loose top type, which is composed of a basic body and a replaceable loose top. In the front end of the basic body, a jaw is formed, which is delimited by two elastically bendable branches and an intermediate axial support surface, and in which the loose top can be securely pinched by inner support surfaces of the branches being resiliently pressed against side contact surfaces of the loose top. The two side contact surfaces of the loose top extend rearward from clearance surfaces that are included in the front end of the loose top. By forming the diametrical dimension between opposite side contact surfaces greater nearer the front end of the loose top, the branches of the jaw securely pinch the loose top in the area of the front ends thereof, where the branches have their maximal bending capacity.
