| 20080240880 | CUTTING INSERT, CUTTING TOOL, AND METHOD OF MACHINING - A cutting insert includes a body having a first surface, a second surface, and an intermediate surface. The intermediate surface includes a generally cylindrical main surface and at least one recess surface extending radially inwardly from the main surface, the main surface and the recess surface extending between the first surface and the second surface. Cutting edges are defined by intersections between the main surface and the recess surface. | 10-02-2008 |
| 20080240872 | CUTTING TOOL WITH REPLACEABLE INSERT SUPPORTING CASSETTE - A cutting tool includes a cutting insert, the insert including a cutting edge. The cutting tool also includes a cassette including an insert clamp for clamping the insert relative to an abutment surface of the cassette, and a generally cylindrical base portion. The cutting tool also includes a tool holder body, the tool holder body having a cylindrical opening in which the base portion of the cassette is disposed. A cassette clamp including a wedge is provided for clamping the cassette relative to the tool holder body. The cutting edge extends beyond a periphery of the tool holder body when the insert is clamped relative to the abutment surface of the cassette and the cassette is clamped relative to the tool holder body. | 10-02-2008 |
| 20080238000 | TOOL WITH REPLACEABLE TIP - A tool with a replaceable tip includes a tool body including a tip holding portion, a tool tip having a shank portion adapted to be disposed proximate the tip holding portion comprising a wall defining an axial opening, the wall having at least one radial opening, at least one locking element being disposed in the radial opening, and, as a clamping ring is turned about the longitudinal axis of the tool body, a locking element contacting surface of the clamping ring contacts the locking element and urges it through the radial opening and into the recess in the tool tip. A method of retaining a tool tip is also disclosed. | 10-02-2008 |
| 20080199263 | Cutting Insert for Turning with Chip-Breaker Arrangement Providing Room for a Cooling Jet - A cutting insert includes a polygonal body of a hard, wear-resistant material, which has an upper surface and a lower surface, and a plurality of edge surfaces uniting said surfaces. At least one chip-breaker arrangement is provided in at least one of the lower and upper surfaces. At least one rounded cutting corner, provided with a nose-cutting edge, is formed at a nose portion at the area of the intersection area of two edge surfaces. The cutting corner defines a bisector. The chip-breaker arrangement includes two elongate chip-breaker segments having an opening provided therebetween intended to give room for a cooling jet directed toward the opening. | 08-21-2008 |
