Abstract: A milling tool has single sided and indexable milling inserts having a round basic shape. Each milling insert has a plurality of tangentially spaced-apart and alternately usable cutting edges, which individually fall archedly from a first end, situated closest to an upper reference plane, to a lowest point, from which it again rises toward a second end. A reinforcing chamfer surface included in the cutting edge is formed with an increasing width in a direction from the first end of the cutting edge toward the second end.

Abstract: A rotating cutting tool configured to rotate around an axis of rotation in a rotary direction, and a support pad for such a tool is disclosed. The support pad defines a central longitudinal axis and has a first longitudinal edge side, an opposite second longitudinal edge side, a first transversal edge side and an opposite second transversal edge side. The support pad includes a first support surface, which is convexly curved as viewed in a plane perpendicular to the central longitudinal axis and a first recess, which extends into the first support surface in a direction from the first longitudinal edge side towards the second longitudinal edge side. The first recess extends to a final position on the first support surface.

Abstract: A milling insert, including an upperside, an underside, and a reference plane parallel thereto. A plurality of indexable cutting edges are formed along a peripheral borderline in transitions between at least the upperside and a number of clearance surfaces. Each cutting edge includes a chip-removing main edge and a surface-wiping secondary edge. The main edge, from a first end of the main edge adjacent to the secondary edge, declines toward the underside of the milling insert and then, from a lowest part, rises toward an opposite second end of the main edge. The secondary edge is inclined at an angle (?) in relation to the reference plane as viewed perpendicularly to the clearance surface of the secondary edge, such that a first end of the secondary edge connected to the main edge is situated on a lower level than the opposite, second end of the secondary edge.

Abstract: A rock drilling shank adaptor includes an elongate body having an internal flushing bore and an entry hole through the sidewall of the adaptor in fluid communication with the internal bore. The flushing hole is optimized to reduce the likelihood of fracture at the wall of the adaptor and in particular includes straight sections at axially forward and rearwardmost regions of the hole.

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 percussive rock drill bit has a head and a shank in which a plurality of flushing grooves extend radially outward and axially rearward from a front face. The flushing grooves are configured to optimize the axially rearward flow of rock particles and fines entrained in the flushing fluid. In particular, each groove is generally convex relative to a longitudinal axis of the drill bit and is declined continuously relative to the axis from a first groove end to a second groove end.

Abstract: An arrangement for controlling the process of rotary chip removing machining of a work piece includes a monitoring system for monitoring the rotary chip removing machining. The monitoring system has at least one surface acoustic wave sensor and at least one first antenna mounted to a cutting tool. At least one second antenna is arranged for wireless communication with the second antenna. Each sensor detects at least one parameter of a group of parameters consisting of strain, temperature and pressure. The sensor and the first antenna transmit the detected at least one parameter to the second antenna in response to an interrogation signal received by the first antenna. A processing unit is connected to the second antenna and transmits the interrogation signal and transmission energy to the first antenna and to the sensor via the second antenna. A control system communicates with the monitoring system to control the machining of the work piece at least partially based on the detected parameter.

Abstract: A milling tool is equipped with milling inserts, below which there are disposed shim plates, the primary function of which is to protect the basic body of the tool in the event of insert breakdowns. The shim plate is formed with a protuberance, in which an auxiliary cutting edge is included, which, in the assembled state of the tool, is located along an inactive cutting edge, which is situated radially inside an active chip removing cutting edge. By means of the auxiliary cutting edge, the milling tool can be utilized for ramping operations without risk of the inactive cutting edge of the milling insert being damaged.

Abstract: A tool for cyclo-palloid gear hobbing includes a head and a plurality of milling inserts protruding from a front side thereof. The milling inserts are mounted, two by two, in chip removal units that are detachably connected to the head. Each milling insert is clamped by a wedge and a screw that are easy to access. The wedge acts tangentially against the milling insert behind which there is a tangential support in the form of a shoulder. By clamping the milling insert with a respective wedge the milling inserts can be mounted and dismounted in a simple way, and each group of wedge+milling insert+tangential support can be located tangentially and thereby efficiently carry the cutting forces acting on the milling insert. In further aspects, an insert holder intended for the tool, a chip removal unit of an insert holder and an insert kit are disclosed.

The shoulder has two knobs mutually separated by a central notch, via which cooling medium can pass from the flushing channel toward the rake surface.
