Abstract:
Bell-shaped milling cutter for producing preferably profiled, arcuate grooves, has a main body in the form of a circular disk and a plurality of cutting edge carriers which extend substantially perpendicularly to the plane of the main body and which are arranged in succession in the peripheral direction along a circular path about the center of the main body and are mounted releasably to the main body. To provide a bell-shaped milling cutter having the features set out in the opening part of this specification, which permits simplified and less expensive production of arcuate grooves without having to forego the precise arrangement and orientation of the cutting bits of the known bell-shaped milling cutters, provided at the main body are positioning devices which permit mounting of the cutting edge carriers in a plurality of mutually different radial spacings on the main body.
Abstract:
A cutting tool includes first and second components, configured for differential coupling with each other. The first and second components each include peripheral and central coupling threads which each extend in a helical direction about a component axis of the respective component. Each component's peripheral and central coupling threads are axially offset with respect to each other. The first and second components each include a radial stop surface located at the respective peripheral coupling thread. In an assembled position of the cutting tool, the radial stop surfaces abut each other and the peripheral and central coupling threads of the first component threadingly engage the peripheral and central coupling threads of the second component, respectively, forming a differential tool coupling between the first and second components.

Milling cutter and method of operating same, and other machine tools, and an adjustment mechanism therefor. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.” The purpose of the abstract is to enable the Patent and Trademark Office and the public generally to determine quickly from a cursory inspection the nature and gist of the technical disclosure. The abstract shall not be used for interpreting the scope of the claims. Therefore, any statements made relating to the abstract are not intended to limit the claims in any manner and should not be interpreted as limiting the claims in any manner.
Abstract:
An insert attached to a tool body of a hole machining tool having an attachment seat and a pressing member for pressing the insert to adjust the position of a peripheral cutting edge in a diameter direction of the tool. The insert has a panel shape. One surface of the insert in a thickness direction provides a seating surface, the other surface in the thickness direction provides a peripheral flank surface. A surface facing the rear side of the insert in a tool rotation direction provides a pressed surface in a state that the insert is attached to the attachment seat. A side surface facing the front side in the tool rotation direction provides an inclined surface, and a peripheral cutting edge is formed at a ridge portion outside of the inclined surface in the diameter direction of the tool.
Abstract:
A metal cutting tool is provided with at least one cutting insert mounted in an insert pocket in communication with an adjusting mechanism, the cutting insert comprising at least one insert adjusting slot extending between two opposing major faces thereof and opening out to each major face at an adjusting aperture and the adjusting mechanism comprising at least one adjusting member having an adjusting member top face underlying the cutting insert while being visible and accessible therethrough.

Abstract:
The invention relates to a cutting tool for metal removal. Said tool comprises a tool base holder (10), which can rotate around an axis and which comprises at least one recess for a cassette which is used as a tool support for a cutting insert (14), also comprising an adjustment device which comprises an eccentric pin (21) for radial displacement of the cassette. According to the invention, an adjusting wedge (18) is associated with the cassette recess and can be displaced in an axial direction by means of the eccentric pin.
Abstract:
The boring tool has an insert upon which one or two boring heads are slidably guided along a swallowtail track. For fixing the boring heads in position, set screws are provided which are adapted to bear against the clamping surfaces of the insert. To preclude radial sliding of the boring heads, even when the set screws are only partially tightened, the clamping surfaces are inclined relative to the longitudinal axis of the insert, and the spacing of the clamping surfaces from the longitudinal axis increases toward the ends of the insert.
Abstract:
A boring cutter which is adapted to be rotated about its central axis includes at least one insert pocket having opposed parallel leading and trailing walls, as well as a bottom wall. An insert seat of generally L-shaped configuration is provided, with the leading surface of the insert seat being in abutting relationship with the leading wall of the pocket. The opposed trailing surface of the insert seat includes both a leading and rear locating support surface adapted to receive an indexable cutting insert. A wedge is receivable between the rear surface of the cutting insert and the trailing wall of the pocket. The radial position of both the insert seat and the wedge, relative to the central axis of the boring cutter is adjustable. By this arrangement, the radial position of the cutting insert may be varied to thereby adjust the effective outer diameter of the boring cutter. In addition, the amount of overhang, or the difference in the radial position between the cutting insert and the wedge, remains constant thereby maintaining the structural support for the cutting edge of the insert.
Abstract:
A boring bar and drill stem insert for boring tools which are positioned at opposite ends thereof and has a transverse recess with a rectangular cross section opening toward the front face of the boring bar and extending at right angles to the axis of the boring bar to accept a drill stem insert of identical cross section. A clamping screw is provided at right angles to the transverse recess and is adapted to clamp the insert in the boring bar. A centering body, for centering the insert, engages a side face of the insert. A centering wedge is provided having a trapezoidal cross section and constitutes the centering body and is received partly in a groove in the front face of the boring bar insert. Both grooves are of a trapezoidal cross section and the wedge can be forced into the grooves by means of a screw extending in the axial direction of the boring bar.
