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 machine tool includes a cutting unit and multiple quick-release elements. The cutting unit includes a handle including two lateral facets, an upper facet, multiple bores made in the upper facet, and multiple cutouts made in at least one of the lateral facets. Each of the cutouts is in communication with a corresponding one of the bores. Each of the quick-release elements includes a cam including an operative portion located further from a rotational axis than an idle portion. Each of the cams is inserted in a corresponding one of the bores. The idle portion of each of the cams is located in the corresponding bore when each of the cams is at a first angle. The operative portion of each of the cams extends from the corresponding bore through the corresponding cutout when each of the cams is at a second angle.

A Quick-Change Tool Holder (QCTH) centerline-position adjustment device is provided herein which is characterized by a device which provides for a plurality of distinct and variable position settings to be selected individually. The individual settings are selected by rotation of an indexable ring which contains a plurality of set screws which can be individually adjusted. The rotation of the indexable ring is about the central shaft which is mounted to the Quick Change Tool Holder.

A tool unit includes a base that is mountable on and demountable from a first turret, a slider that is disposed on the base, holds a cutting tool in a state in which a direction of the linear cutting blade of the cutting tool is inclined with respect to a Z-direction by a predetermined angle when seen from an X-direction, and is able to move in a Y-direction perpendicular or substantially perpendicular to both the X-direction and Z-direction, and a drive transmission that is disposed on the base and is connected to a tool drive unit to move the slider.

Methods, systems, and/or the like are provided for an adapter. An adapter may include a block having a top surface, a bottom surface, and four sides; at least one adapter pocket configured to receive at least a portion of a toolset adapter for a toolset, wherein the adapter pocket is disposed on the top surface of the block; a plurality of fastener holes, each of the plurality of fastener holes being configured to receive one or more fastening devices, wherein the plurality of fastener holes are disposed annularly around the at least one adapter pocket; a plurality of machine attachment holes configured to receive one or more fasteners and thereby secure the adapter to a machining device, wherein the plurality of machine attachment holes are disposed on the top surface of the block; and a fluid hole being configured to receive one or more fluids.
