The mounting portion includes a frustoconical supporting surface tip portion and a frustoconical threaded portion. The present invention also relates to a cutting tool per se.

Abstract: The present invention relates to a tool and a male part for chip removing machining. The tool includes a male part and a holder for the male part. The male part includes a radial and axial supporting and positioning portion and a threaded portion. A largest diameter of the externally threaded portion is smaller than a smallest diameter of the radially and axially supporting and positioning portion. A transition portion is disposed along the axis of the male part between a radially largest portion of the radially and axially supporting and positioning portion and the externally threaded portion.

Abstract: The present invention relates to a tool head preferably for milling. The tool head is connectable to a toolholder. The tool head includes a cutting portion and a mounting portion. The mounting portion includes an axial stop surface and a radial stop surface. Dimensions and tolerances of the axial stop surface and the radial stop surface are selected such that the axial stop surface will abut an axial stop on the toolholder to prevent axial movement of the toolholder relative to the tool head beyond the axial stop surface and the radial stop surface will be disposed proximate a radial stop of the toolholder to limit radial movement of the tool head relative to the toolholder when an integral fastening portion of the tool head and an integral fastening portion of the toolholder are fastened directly to one another and the axial stop surface and the axial stop abut.

Abstract: An indexable insert includes an insert body including a plurality of cutting edge portions and an insert hole arrangement for permitting the insert to be secured to a toolholder. The insert hole arrangement includes at least one securing screw-receiving hole. The insert hole arrangement is configured to permit a securing screw to extend through the insert body along any one of at least two different axes through the insert hole arrangement, the insert hole arrangement including a screw abutment surface for abutting against the securing screw.

Abstract: A cutting tool for, e.g., dressing electrode tips includes a toolholder having an opening extending through the toolholder from a top of the toolholder to a bottom of the toolholder along a central axis of the toolholder, and a plurality of insert mounting pockets disposed around the opening for mounting replaceable cutting inserts, the plurality of insert mounting pockets including a center pocket, a top pocket, and a bottom pocket. The tool also includes a center insert removably disposed in the center pocket, a top insert removably disposed in the top pocket, and a bottom insert removably disposed in the bottom pocket. When a top electrode tip and a bottom electrode tip are disposed in a dressing position relative to a top and a bottom of the opening in the toolholder and the tool is rotated, the center insert and the top insert dress the top electrode tip, and the center insert and the bottom insert dress the bottom electrode tip.

Abstract: A milling tool includes a milling body and a plurality of cutting inserts. The milling body has fastening devices to hold the cutting inserts in a plurality of respective insert pockets each having at least one base surface. Each of the cutting inserts has at least one cutting edge. The tool has a rotational axis and a rotational direction, as well as a feed direction and an end surface. The milling tool is provided to cut a work piece substantially in an axial direction of the tool, which is substantially perpendicular to the feed direction.

Abstract: The present invention relates to a thread milling cutter, which includes a cutting head, having a holder with a number of cutting insert pockets, a number of threading inserts, which are received in the cutting insert pockets and an attachment integrated with the cutting head, which attachment is intended to be received in a tool coupling. The invention also relates to the holder per se and to a method for milling an external thread on a spigot. The holder is provided with an internal cavity, which has an extension both radially and axially with regard to a rotational axis of the thread milling cutter, and the cutting insert pockets are provided in the internal cavity.

Abstract: Felt changing device and procedure for changing an endless felt, in which procedure an endless felt is placed around rollers. In the procedure, an elongated lifting beam (4) with the endless felt (5) placed around it is attached to the first end (3) of a first roller (1). The fixtures holding the first end of the first roller secured are released and the first end of the roller, supported by the lifting beam, is raised. The felt around the lifting beam is passed under the first roller and around the first roller and the other rollers (2) and the first roller is lowered and secured.

Abstract: A tool for cutting machining includes a holder, a cutting head and a threaded fastener for fastening the cutting head to the holder. The cutting head is formed of injection molded cemented carbide and includes at least one cutting edge. The holder has a front surface and the cutting head has a support surface provided to releasably abut the front surface substantially in a radial plane. A central blind hole is provided in the support surface. An insert formed of a material softer than injection molded cemented carbide is secured in the blind hole. The insert includes a thread cooperating with a thread of the fastener for pulling the cutting head toward the holder in response to rotation of the fastener. By further tightening the fastener after the support surface abuts the front surface of the holder, the contact between the thread of the fastener and the thread of the insert forces the insert radially outwardly against a wall of the blind bore.

Abstract: A tool includes a cutting head and a holder, wherein the cutting head and the holder form two cooperating surfaces that are pressed together. The surfaces possess rows of alternating parallel grooves and ridges for locking the surfaces to each other. Each of the surfaces has two rows of grooves, one row oriented 90.degree. relative to the other row. On one of the surfaces, some of the grooves of one row are in non-intersecting relationship with the grooves of the other row. On the other surface, the rows extend completely across one another, whereby the rows together form a waffle-like pattern. The cooperating surfaces allow at least four separate relative positions between the cutting head and holder.
