摘要： A cutting tool includes a cutting head and a tool shank, each having an axial abutment surface. One of the two includes a coupling pin, while the other includes a pin receptacle and a clamping through bore that opens out to the pin receptacle. The coupling pin has an engagement groove and the pin receptacle has an engagement ridge. The coupling pin is received into the pin receptacle. The cutting head and tool shank are releasably attached together by a fastening member that passes through the clamping through bore and acts on the coupling pin so that the engagement groove abuts the engagement ridge and the axial abutment surfaces on each part abut each other.

摘要： A rotary cutting tool has an insert receiving pocket with a cutting insert removably secured therein and an adjustment recess rearward thereof having a radially outward facing recess side surface and an adjustment tongue spaced apart therefrom by a first inner passage. The adjustment tongue extends rearwardly from a tongue root to a tongue tip and includes a tongue through bore. The tongue root has a shoulder surface facing in the forward direction and the cutting insert is in contact with the shoulder surface. An adjustment screw extends through the tongue through bore and engages the recess side surface, and rotation of the adjustment screw causes axial displacement of the cutting insert in a forward direction. An imaginary straight line in the first inner passage intersects a recess rear end surface formed on a first body sub-portion of the cutting body which is integrally formed with the adjustment tongue.

摘要： A cutting tool includes a cutting insert resiliently clamped in an insert holder. The insert holder includes a forwardly located insert mounting portion that includes an insert receiving recess which extends along a recess axis. The insert holder includes a fastening member through hole opening out to the insert receiving recess. The insert receiving recess includes an insert orientation projection. The fastening member through hole has a through hole angular extent about the recess axis. The insert orientation projection has an insert orientation projection angular extent about the recess axis. The insert orientation projection angular extent at least partially angularly overlaps the through hole angular extent about the recess axis.

摘要： A double-ended parting cutting insert. The cutting insert includes two cutting portions at opposite ends thereof which are oriented at 90° to each other. The cutting insert includes a pair of rake and support engagement grooves, the rake and support engagement grooves of each one of the pair converging in a direction away from a respective cutting portion. An insert holder includes a clamping portion having a resilient upper clamping jaw having an upper engagement ridge and a lower base jaw having a lower engagement ridge. A gap therebetween forms an insert receiving slot that has a slot opening. The upper and lower engagement ridges converge in a direction away from the slot opening. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the cutting insert is located in the insert receiving slot and resiliently clamped therein.

摘要： A method for cutting a thread on a rotating workpiece by means of a cutting tool having a cutting edge. The method includes sequentially performing a number of passes, each pass includes simultaneously moving the cutting tool and/or the workpiece relative to each other along and oscillating the cutting tool towards and away from workpiece rotational such that the cutting edge exits and enters the workpiece forming an air cut. The air cuts performed in a final pass are longer than all the other passes.

摘要： An elongated tool holder includes a mass housing portion having a housing peripheral surface, an outer sleeve having a sleeve hole wall surface, and an anti-vibration arrangement. An elongated groove is formed in one of the housing peripheral surface and the sleeve hole wall surface. In an assembled state of the tool holder, the groove, which is located at a common interface of the housing peripheral surface and the sleeve hole wall surface, forms a groove coolant channel. The groove coolant channel forms part of an overall tool holder coolant channel which is spaced apart from the anti-vibration arrangement, and thus isolates the coolant from the anti-vibration arrangement. A cutting tool incorporates the tool holder.

摘要： A tool holder having a holder body, an opening of the holder body having opposing upper and lower jaws respectively defining upper and lower pocket surfaces of an insert receiving pocket, and a resilience slot extending away from the insert receiving pocket. A first plane intersects the upper and lower pocket surfaces, and an actuating member extends from the upper jaw along a first axis in a downward direction and traverses the resilience slot. The lower jaw includes an access bore, and a locking member occupies the access bore and engages a locking portion of the actuating member. The upper jaw has a top jaw surface facing in an upward direction, and the first axis intersects the top jaw surface. A cutting tool is configured with the tool holder and a cutting insert removably secured in the insert receiving pocket.

摘要： A cutting tool assembly having a longitudinal axis establishing upward and downward directions, includes a Y-axis parting adaptor mounted onto a holder. The parting adaptor has an insert pocket including a base jaw configured to support a cutting insert. The holder has a holder head portion and a shank portion. The holder head portion has an adaptor pocket in which the parting adaptor is mounted. If the holder shank cross-sectional shape is square or rectangular the forwardmost cutting edge is directly above the forwardmost holder shank surface, and if the holder shank cross-sectional shape is round and a centrally extending holder shank axis extends to the forwardmost cutting edge.
