摘要： Milling tool holder which comprises a first holder part, a second holder part, and a locking mechanism. The first holder part comprises a first cutting insert receptacle for receiving a first cutting insert and a second cutting insert receptacle for receiving a second cutting insert. The second holder part which, for adjusting a milling width, is variably positionable with respect to the first holder part along a longitudinal axis, comprises a third cutting insert receptacle for receiving a third cutting insert and a fourth cutting insert receptacle for receiving a fourth cutting insert. The locking mechanism is configured to fix the first and second holder parts to the adjusted milling width. The first holder part and the second holder part are positioned with respect to one another in such a manner that the third cutting insert receptacle is arranged in the circumferential direction between the first cutting insert receptacle and the second cutting insert receptacle, and that the second cutting insert receptacle is arranged in the circumferential direction between the third cutting insert receptacle and the fourth cutting insert receptacle.

摘要： A milling cutter includes a front end part and a back end part. The front end part includes a disc-shaped cutter body having a front side, a rear side, a central axis, and a number of insert seats. A primary holding member extends from the rear side. The back end part includes a secondary holding member, which engages the primary holding member when the front and back end parts are mounted to each other. The disc-shaped cutter body has a central cylindrical aperture extending coaxially with the central axis and including an inner cylindrical surface. An outer cylindrical surface is provided on a front portion of the secondary holding member. The inner cylindrical surface abuts the outer cylindrical surface in an abutting region between the front and the rear sides to center the front and back end parts.

摘要： An internal milling cutter includes a carrier disk having a centre axis defining an axis of rotation of the milling cutter, a plurality of separated tool holder segments removably mounted at the inner circumference of the carrier disk, and at least one clamp for each tool holder segment mounted either on the carrier disk or on the tool holder segment. Each of the tool holder segments at its inner circumference includes at least one cutting insert seat with a mounting element for a cutting insert or at least one cutting edge. The clamp is located and arranged such that it generates a force in the axial direction pressing the axial contact surface of the tool holder segment onto the axial abutment surface of the carrier disk, and the clamp is mounted movably in a radial direction of the carrier disk between a locking position and a releasing position.

摘要： A hardware fastener with a movable threaded element suspended within a cavity formed in a body. The movable threaded element has an internal surface with threads for cooperating with a threaded fastener. The movable threaded element is suspended in the cavity by the one or more spring-like members such that an area, A, of reduced stiffness is created in the cavity proximate the movable threaded element, thereby allowing the movable threaded element to move a predetermined distance within the cavity when torque is applied to the threaded fastener. The one or more spring-like members store elastic potential energy to prevent the loss of pretension of the threaded fastener that can be caused by heat or vibration. The invention also eliminates the need for a torque wrench when tightening the threaded fastener to a specified torque value.
