A tool for machining a groove of a rotation-symmetric component, preferably a piston of an internal combustion engine, is provided. The machining is carried out by a rotation of the tool around an axis of symmetry of the rotation-symmetric component to be machined. The tool includes at least one arm disposed in such a way that a circumference of the rotation-symmetric component can at least be partially enclosed. Also, a machining device for machining of the groove is provided on the at least one arm. At least one adjusting device is provided to adjust a contact force of the at least one machining device on the rotation-symmetric component, and to adapt the tool to different diameters of the rotation-symmetric component.

Device for producing tooth replacements, which device has a milling cutter (36) for shaping the front face of the tube portion (16), which milling cutter (36) has at least one abutment face which is intended to bear at least indirectly on a surface of the abutment (10), in particular on the collar (14) of the abutment, and via which milling cutter (36) the length or height of the tube portion (16) of the abutment (10) can be fixed, in particular the tube portion can be shaped. Tool set consisting of a milling cutter (36) and of a sleeve (42), wherein at least one abutment face (76) is formed on the milling cutter and extends towards the sleeve (42), and wherein the sleeve (42) has a supporting face (78), in particular for supporting on an abutment (10).

The milling cutter according to the present invention consists of insert holders where these insert holders project from a carrier disc which is adapted for clamping onto the spindle of a machine tool, and the individual holders are connected with one another by braces. Arms are provided between the holders and the carrier disc,

A cutting insert for a milling tool including an upper side having a central surface, a lower side, a peripheral side surface, and a cutting edge formed between the upper side and the peripheral side surface. The cutting edge having a positively inclined main cutting edge projecting at least partly above the central surface. The upper side includes a rake surface extending inside of and along the at least one cutting edge, sloping downward toward the central surface. A plateau, elevated with respect to the central surface and extending along the main cutting edge, is formed inside the rake surface. A transition between the rake surface and the plateau extends at an angle .sub.2 with respect to an upper extension plane, wherein .sub.2>0.

An indexable roughing end mill capable of suppressing generation of chattering is provided. When the positions of cutting inserts (40) arranged in each spiral groove (28) are defined as a first segment to an n.sup.th segment (where n is an integer of 2 or higher) from a leading end surface (22) side of a tool body (20) toward a base end surface (21) side, all of the angles (1 . . . m (where m is an integer of 2 or higher)) between lines connecting a rotational axis (O) and the cutting inserts (40) in the first segments of the respective spiral grooves (28) are different from each other, as viewed from the leading end surface side of the tool body (20), and an angle (t) between the cutting insert (40) in the first segment and the cutting insert (40) in the n.sup.th segment (the uppermost segment) in a spiral groove 28 is different from any of the angles 1 . . . m (where m is an integer of 2 or higher) between the lines, as viewed from the leading end surface side of the tool body (20).

Various components of an electronic device housing and methods for their assembly are disclosed. The housing can be formed by assembling and connecting two or more different sections together. The sections of the housing may be coupled together using one or more coupling members. The coupling members may be formed using a two-shot molding process in which the first shot forms a structural portion of the coupling members, and the second shot forms cosmetic portions of the coupling members.

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 plurality of slots formed in the outer surface. The plurality of slots arranged in a staggered row between the first end and the second end of the body. The milling cutter also includes a plurality of cutting insert removably secured to the body. Each cutting insert is positioned at least partially within one of the plurality of slots and includes a cutting profile defined by rounded peaks and pointed valleys to cut a tooth form into a saw blade. The plurality of cutting inserts are staggered such that the plurality of cutting inserts are circumferentially offset from each other along a longitudinal axis of the milling drum.

The milling cutter according to the present invention consists of insert holders (2) where these insert holders (2) project from a carrier disc (1) which is adapted for clamping onto the spindle of a machine tool, and the individual holders (2) are connected with one another by braces (3). Arms (5) are provided between the holders (2) and the carrier disc (1).

A cutting tool may include a circular columnar body extending from a first end to a second end along a rotation axis. At least a part of the columnar body may correspond to an insert including a cutting edge at the first end. The insert may include therein a flow path extending from a side of the first end toward a side of the second end. A width of the flow path along a radial direction of the circular columnar body may be smaller than a width of the flow path along a circumferential direction of the circular columnar body in a cross section orthogonal to the rotation axis.
