A rear wall formed at the rearward end and connects the first and second side walls. The tool head also includes an insert retaining portion proximate the forward end, and a coupling portion which extends in the direction of the rearward end and includes vertically spaced apart top and bottom coupling arms separated by a coupling recess opening out to the rear wall.

A method for producing a metal cutting tool component and a metal cutting tool component. The method includes the step of producing a front module having a main body and a front module interface at a rear end thereof, providing an intermediate element and building, using an additive manufacturing process, the main body on the build surface of the intermediate element. Further, a rear module including a coupling part at a rear end thereof and a rear module interface at a front end thereof is provided, and mounting the front module on the rear module by immovably connecting the front module and rear module interfaces, after the front module has been mounted on the rear module, machining at least one surface of the main body, and heat treating the intermediate element with the built main body, wherein at least the main body is hardened.

A shank for a tool bit employing an offset arrangement is provided, the shank being able to respond to various types of machining through replacement of heads and having a structure to save time and steps necessary for such replacement of the heads. A cutting tool having such shank is also provided.

A shank 53 of a head-replaceable cutting tool has at least one head attaching part 53A, 53B that is arranged off-center relative to an axis 53X of the shank 53. The axis 53X of the shank 53 corresponds to an axis extending in a longitudinal direction of the shank 53, and the head attaching part 53A, 53B may be arranged so as to be off-center in a direction perpendicular to the axis 53X.

Provided is a tool head in a head replaceable cutting tool configured on the basis of a novel idea so as to allow external measurement to be easily performed, while allowing cutting performance to be maintained. The tool head in the head replaceable cutting tool has a substantially cylindrical shape, and can be fastened to a shank held on a machine tool, and moreover includes an insert mounting seat on which a cutting insert is to be detachably mounted, the tool head further including a point, a line, or a surface that defines a reference surface from which a cutting edge of the cutting insert has a predetermined length to a predetermined portion thereof.

Tool holder for a tool for machining workpieces, with a tool holder body, which defines a longitudinal axis, on which a tool mount for securing a tool is formed and on which a tool holder interface for fixating the tool holder to a holder shaft is formed, wherein the tool holder interface comprises: a tool holder plane surface oriented transversely to the longitudinal axis, against which a holder shaft plane surface can abut to establish a defined relative position in longitudinal direction between the tool mount and the holder shaft, a tool holder cone section, which is polygonal in a cross-section and which can engage with a correspondingly polygonal holder shaft cone section to establish a defined relative position in tangential direction between the tool mount and the holder shaft, and a tool holder cylinder section which can act together with a corresponding holder shaft cylinder section.

The invention relates to a device and method for a tool change in a driven or stationary tool holder using at least one industrial robot. A drive device for clamping and releasing the tool in a tool holding fixture of the tool holder prevents incorrect operation and can be operated manually or by the handling robot and can be actively locked to the tool holder.

A cutting tool assembly includes a first tool part and a second tool part. The first tool part has a forward end portion including a cutting edge and a rearward end portion having a conical section and an engagement section. The second tool part includes a conical recess and a clamping device rearwards the conical recess. The clamping device is provided in a transversal cavity of the second tool part and has a first clamp block, a second clamp block and a differential screw engaging the first and second clamp blocks. The first and second clamp blocks engage the engagement section of the first tool part to pull the first tool part into the conical recess when the first and second clamp blocks are moved towards each other by the differential screw protruding rearwards from the first and second clamp blocks.

A cutting head attachment assembly for a cutting tool includes a body forming an axially forward part of the cutting tool attachable to a cutting head via a clamping element and a fixation element. A guide surface provided at the body or cutting head extends in both a radial and an axial direction to support movement of the clamping element in both the radial and axial directions via actuation of the fixation element to force and clamp together axially the head and body.

A machine tool comprises a tool carrier, e.g. in the form of a turret disc (7) that is provided with receptacles (8) for tool holders (9), wherein each tool holder and tool carrier comprise support surfaces associated to each other and devices for fixing the tool holder at the tool carrier. At least one clamping element is provided at the tool carrier (7) that is adjustably supported between a clamping position and a release position in a direction transverse to a tie rod of a tool holder arranged on a slider (22) receptacle of the tool carrier. The clamping element is provided with a first clamping surface (24) that can be brought into engagement with a second clamping surface (35) at the tie rod of the tool holder in a self-locking and releasable manner.

A cutting tool for turning includes a coupling portion, an intermediate portion and a cutting portion. The intermediate portion extends along a longitudinal center axis thereof between the coupling portion and the cutting portion. The cutting portion includes a first and a second nose portion. The first nose portion has a first cutting edge, a second cutting edge, and a convex nose cutting edge connecting the first and second cutting edges. The first and second cutting edges form a nose angle less than 90°. A longitudinal center axis of the coupling portion defines a tool rotational axis. The cutting portion includes a top surface, the top surface facing away from the coupling portion and the first and the second nose portions each form free ends of the cutting tool.
