摘要： A tool for the machine working of workpieces is more particularly provided for universal machines, which automatically work very small workpieces by different lathe working operations. A cutting insert (13) can be fixed in a tool holder (14) by means of a fixing screw (19). The cutting insert (13) is constructed as a reversing plate and has two conical receptacles for the conical gripping head (25) of the fixing screw (19). This reversing plate has several use possibilities, such as grooving, plunge and turn, threading, front turn, back turn and cut off. The central opening (30) in the cutting insert is connected by means of a slot (36) to the narrower trapezoidal surface (35) of the cutting insert, the slot (36) being sufficiently wide to fit over the shank of the fixing screw (19). Thus, after loosening the fixing screw, the cutting insert can be removed laterally and correspondingly fitted again. The screw (19) is captive and can also be operated from the back (48) of the tool holder (14).

摘要： A rotatable tool includes a rotatable body defining an axis of rotation. The body forms a seat configured to receive a cutting insert. The seat includes a bottom surface and a radial support upstanding therefrom. The bottom surface includes a screw-receiving hole which intersects the bottom surface to form a port therein. The screw-receiving hole includes a female screw-threaded portion spaced from the port by a non-threaded portion. A fastening screw secures the cutting insert to the body. The screw includes a shaft having at one end thereof a male screw thread connectable to the female screw threaded portion, and at an opposite end thereof a head. The shaft also includes a non-threaded portion disposed between the male screw thread and the head and sized to be received in the non-threaded portion of the screw-receiving hole. The port and the non-threaded portion of the screw-receiving hole have a non-circular shape that is elongated generally in a radial direction relative to accommodate bending deflection of the non-threaded portion of the screw when the screw is tightened.

摘要： A boring bar tool for use with a tip is disclosed which has a tool body. The tip is mounted to one side of a forward end of the nose of the tool body. A neck is formed at a proximal end of the nose, and a shank in the form of a shaft is formed at a proximal end of the neck. The neck has a cross-sectional area in a plane perpendicular to an axis of the shank which is larger than the cross-sectional area of the shank in the plane.

摘要： A boring bar assembly having a symmetrical carbide tip holder for turning a brake drum and which can be rotated 180 degrees for facing either or both sides of a rotor of a disc brake. A hexagonal bar provides a housing for receiving a depth of cut mechanism including a dial at one end of the bar. A movable dial rod is connected to the dial mechanism and extends through the housing and engages a tool bit holder at the other end of the bar. A carbide tip is positioned and clamped in one of two undercut pockets on opposite sides of the flat head of the bit holder. The holder includes an angular surface engaging the dial rod so that the holder is moved toward and away from the axis of the housing in response to the dial rod. A spring-loaded tool retractor is provided in a bore of the housing and includes an angular end surface which is yieldably urged against a portion of the angular surface of the holder. When the dial rod is retracted and moved away from the holder, the end surface of the retractor slides along the angular surface of and into the holder which retracts the holder toward the axis of the housing.

摘要： A cutting tool assembly comprising a cutter body which mounts at each of its opposite sides on one end and at the proper cutting angles a relatively narrow rectangular shaped cutter blade and a triangular shaped cutter blade. These cutter blades are maintained in an operative position in engagement with each other by a clamping element that is releasably joined to the cutter body at an angle that is related to the cutter cutting angles. Support and locking provisions further facilitate maintaining this operative position. Between these cutter blades a holder for another cutter blade is supported on the cutter body. This latter cutter blade and the triangular shaped blades are aligned along with the rectangular shaped cutter blades so as to machine a plural surface profile on a work piece.

摘要： A double sided V-shaped cutting insert includes insert front and back surfaces and a peripheral surface extending therebetween. The peripheral surface has a forward surface, a first planar converging surface, and a first rake surface extending between the forward surface and the first converging surface. A second planar converging surface forms a convergence angle φ, 30°≤φ≤45° with the first converging surface. A second rake surface extends between the forward surface and the second converging surface. In a view perpendicular to the insert front surface, the cutting insert exhibits mirror symmetry about a bisector plane passing between the first and second rake surfaces. The first and second rake surfaces each face away from the bisector plane. The first rake surface tends towards the bisector plane more than the first converging surface, and the second rake surface tends towards the bisector plane more than the second converging surface.

摘要： A non-indexable, one-sided cutting insert includes opposite insert side surfaces which define an insert width therebetween, opposite insert front and rear surfaces which extend between the insert side surfaces and define an insert depth therebetween and opposite insert top and bottom surfaces which extend between the insert side surfaces and the insert front and rear surfaces. The insert top and bottom surfaces define an insert height therebetween. The insert further includes a main cutting edge formed at an intersection between the insert top and front surfaces. A maximum value of the insert width is smaller than minimum value of the insert height, and a minimum value of the insert depth. The insert includes a deep opening which opens out only to the insert bottom surface and defines an opening depth. A depth ratio defined between the opening depth and the insert height is greater than 0.3.

摘要： In an embodiment, a cutting insert includes an upper surface, a one or more side surfaces, and a cutting edge. The upper surface includes a first corner portion, and a first side that is adjacent to the first corner portion. The one or more side surfaces are adjacent to the upper surface. The cutting edge is disposed on at least a portion of a section where the upper surface and the side surfaces intersect. When viewed from directly above, the cutting edge includes first, second, third and fourth cutting edges. The first cutting edge is disposed at the first corner portion and has a convex curved shape. The second cutting edge is next to the first cutting edge, and has a linear shape. The third cutting edge is next to the second cutting edge, and has a convex curved shape. The fourth cutting edge is next to the third cutting edge on the first side.
