摘要： The invention relates to a method for determining a working depth of a tool. The method includes arranging a tool and a depth determination device on a depth setting device; and applying a predetermined compression force in axial direction to the depth determination device, such that at least a part of the depth determination device is elastically compressed by a certain compression amount against a contact surface, obtaining a compressed state of the depth determination device. The method further includes securing a mounting device to a clamping region of a shaft of the tool in the compressed state of the depth determination device such that the mounting device is firmly mounted to the clamping region, whereby a tool assembly is formed; releasing the compression force from the depth determination device, and removing the tool assembly from the depth setting device.

摘要： A milling head for a ball track milling cutter includes an imaginary center axis, a first, working-side end and a second, clamping-side end opposite the first end when viewed along the central axis, and comprising at least one geometrically defined cutting edge, extending along a cutting edge profile of the cutting edge from a first cutting edge end facing the first end of the milling head in the direction of the second end of the milling head up to a second cutting edge end facing the second end of the milling head, wherein at least one cutting edge is formed as an intersecting line between the rake face associated with at least one cutting edge and a first flank face associated with at least one cutting edge, wherein at least one cutting edge is assigned a negative rake angle, a first clearance angle and a wedge angle. It is provided that a value of the negative rake angle in the region of the first cutting edge end has a different value than in the region of the second cutting edge end, that the first clearance angle in the region of the first cutting edge end has a different value than in the region of the second cutting edge end, and that the wedge angle along the cutting edge profile is constant.

The guiding element and the guiding receptacle extend perpendicularly to the center axis of the main body of the tool. The guiding device of the tool has a single guiding element and/or a single guiding receptacle, and the guiding element has an elongated elevation and the guiding receptacle has an elongated recess.

摘要： A drill bit has a tool shank, a center axis, a first cutting region with at least one geometrically defined first cutting edge, the same having a cutting face arranged at a radial distance from the center axis of the drill bit. The first cutting edge forms a countersink angle with the center axis. The drill bit having a chip shaping stage functionally assigned to the first cutting edge formed by the cutting face of the first cutting edge and by a shoulder surface adjoining the cutting face and forming a shoulder angle with the same, wherein the shoulder angle is greater than 90°, and preferably greater than 100°. The cutting face runs at a radial rake angle with respect to an imaginary radial line which cuts the first cutting edge, the same functionally assigned to the cutting face. The radial rake angle is positive.

摘要： The invention relates to a tool for the machining of bores. The tool includes a tool body with a centre axis and a tool end face. At least two secondary cutting edges are formed on the tool body; each secondary cutting edge of the at least two secondary cutting edges, starting from a cutting corner corresponding with the secondary cutting edge on the tool end face, extending in the direction of the centre axis towards a shaft end of the tool in a helical manner with a specific twist pitch. A support collar adjoins each of the secondary cutting edges at a distance, measured in the direction of the centre axis, of at least 0.18 times up to at most 0.28 times the specific twist pitch from the corresponding cutting corner, which support collar extends in the circumferential direction at least up to 1700 to the corresponding cutting corner.

摘要： An expansion clamping device includes a base body and an expansion socket. The expansion socket is inserted into the base body to form a pressure chamber. The pressure chamber can be applied with a hydraulic medium while elastically deforming the expansion socket, in order to achieve a clamping effect in a receiving space which is open in the axial direction of the base body towards a face side and is surrounded by the expansion socket in the circumferential direction. The expansion socket has an elastically deformable clamping section and a collar projecting outwardly in the radial direction on the face side. The expansion socket bears with a bearing surface of the collar in the axial direction against a contact surface of a contact shoulder of the base body and, at least in the region of the bearing surface, is firmly connected, in particular by a material bond, to the base body. The clamping section transitions into the collar in a transition region, a recess being formed in the expansion socket in the transition region in such a way that the transition region overlaps over the contact shoulder of the base body in regions, the bearing surface of the expansion socket bearing against the contact surface in a radially outer contact region thereof, and the contact surface having a radially inner free region adjacent to the contact region, in which free region the expansion socket does not bear against the contact surface.
