20180264562 · 2018-09-20 ·

A cutting tool includes a tool holder, having a holder pocket with a pocket opening, and a cutting member releasably retained therein. The tool holder includes an adjustment cavity that includes circumferentially merging threaded and guiding bore portions. The tool holder further includes an adjustment arrangement that includes an adjustment member including a wedge adjustment portion and a guiding portion integrally formed therewith. The adjusting arrangement further includes an adjustment screw. The wedge adjustment portion is located in the pocket adjustment region and the guiding portion is located in the guiding bore portion and partially protrudes into the threaded bore portion. The adjustment screw is threadingly rotatable between a first rotated position and a second rotated position, and in the second rotated position the adjustment member, and thus the cutting member, is located closer to the pocket opening than in the first rotated position.

GROOVER WITH PEENING FLANKS
20180141135 · 2018-05-24 ·

According to one aspect of this disclosure, a grooving tool is provided. The grooving tool has a body with a plurality of recesses. Plural inserts assembled into each of the recesses. The recesses include a cutting edge for forming grooves in an engine cylinder wall when rotated in one rotational direction. The insert also includes a peening surface extending in the opposite rotational direction from the cutting edge for deforming the upper edges of the grooves when rotated in an opposite rotational direction.

MILLING CUTTER

A milling cutter includes a milling drum having a body with a first end, a second end, an outer surface extending around a circumference of the body between the first and second ends, and a slot formed in the outer surface. The milling cutter also includes a cutting insert positioned at least partially within the slot and removably secured to the body. The cutting insert includes a cutting profile defined by rounded peaks and pointed valleys to cut a tooth form into a saw blade.

INSERT TYPE TOOL AND THREAD MILL
20180117685 · 2018-05-03 ·

An insert portion (3) of a thread mill (1A) is fixed to a leading end portion of a body (2A) using screws (8). The insert portion (3) is configured by overlaying an insert (4) for finish machining and an insert (5) for rough machining. On respective mating faces of the inserts (4, 5), convex portions and concave portions of the mating face of the insert (4) are overlaid with concave portions and convex portions of the mating face of the insert (5). The thread mill (1A) can cut a female screw in a hole formed in a workpiece by performing right-hand cut down-cut milling, for example. The inserts (4, 5) simultaneously cut an inner peripheral surface of the hole, and the rough machining and the finish machining can thus be performed in a single pass. By the convex portions and the concave portions of the respective mating faces of the inserts (4, 5) being overlaid with each other, the inserts (4, 5) partially overlap in their respective thickness directions. As a result, a protrusion length of the insert portion (3) can be shortened.

Cutter

A cutter includes: a cutter main body rotated; and cutting edges disposed on an outer periphery of a front of the cutter main body, wherein a mounting hole penetrating through the cutter main body is formed, an opening portion opening in a front of the cutter main body, a housing portion provided on a rear of the opening portion to house a head portion of a headed bolt, and a female thread portion are formed in the mounting hole, a mounting part including a male thread portion in an outer periphery is mounted to the female thread portion, the male thread portion screwable to the female thread portion, and a through hole having a smaller inner diameter than the head portion is formed in the mounting part.

Tool for the turning/turn broaching of workpieces

A tool for the turning/turn broaching of workpieces is provided, including a carrier which can be attached directly or indirectly to a machine tool with a plurality of segments which are fastened to the carrier. Each of the segments is provided with a plurality of tool bits. In addition, each of the segments is attached to the carrier by at least two fastening elements, which act obliquely to a plane (E) lying perpendicular to the rotational axis (R) of the tool.

Milling tool
09669478 · 2017-06-06 · ·

A milling tool has a tool shank and a cutting head fastened to the forward end of the tool shank by way of a clamping connection. The clamping connection has a protrusion with clamping faces, and a recess with centering faces that interact with the clamping faces. Each of the centering faces has a first region where the centering faces are spaced from a longitudinal axis of the tool shank by a first distance and a second region at a smaller distance. The first region merges into the second region. The clamping faces of the protrusion are introducible into the recess between the first regions of the centering faces and are movable, by rotation of the cutting head about the longitudinal axis, into a clamping position in which the clamping faces interact in a force-fit with the second regions of the centering faces.
