A milling tool for an angle grinder has a supporting body, in the shape of a disk and able to be rotationally driven in a direction of rotation, which has an upper side and an underside. The supporting body is formed as a composite body of fiber-reinforced plastic. Cutting element chambers are formed in the supporting body, open to underside, in each of which one cutting element is replaceably arranged.

Disclosed is a tool for processing an engine block. The tool for processing the engine block includes: multiple cutting inserts; and main cutting edges which are formed at end portions of the inserts, respectively, in which the main cutting edge has a positive axial inclination angle and a radial inclination angle of 5 degrees to 0 degree.

A low profile peripheral cutter (18) with stick blades (6). The cutter has a cutter body (30) and a flexible clamping disk (20) to clamp all blades. The flexible clamping disc includes a slot (24) between each cutting blade (6) in order to provide a plurality of blade clamping web wings (26) each of which acts like a deflection beam to hold the blades in position. Preferably, each web wing (26) covers one stick blade (6) and each web wing has two contacting pads (36, 38) to press each blade into its seating surface (44, 46) thereby holding the blade in position.

A cutting insert and a gear milling cutter is disclosed. A first major side portion of an insert body of the cutting insert is provided with a first recess having a first bottom surface (24a) and a second major side portion is provided with a second recess having a second bottom surface. The first and second bottom surfaces extend substantially in parallel with a longitudinal axis of the insert body. A first minor side portion is provided with a third recess having a third bottom surface and a second minor side portion is provided with a fourth recess having a fourth bottom surface, the third and fourth bottom surfaces extending across the longitudinal axis. Thus, the cutting insert may be supported in a relevant gear milling cutter against one of the first and second bottom surfaces and against one of the third or fourth bottom surfaces.

An indexable cutting insert for milling of a root between two cogs of a cog wheel includes a top surface forming a chip surface, a bottom surface, a side surface forming a clearance surface, a first and a second curved cutting edge formed at an intersection between the top surface and the side surface for milling of the root between the two cogs. The bottom surface includes a first planar abutment section and a second planar abutment section. A first groove extends in the first abutment section and a second groove extends in the second abutment section, each along an axis parallel to a virtual line connecting the apexes of the first and second cutting edges. A first and a second stop section extend across the virtual line, wherein the first stop section protrudes above the first abutment section and the second stop section protrudes above the second abutment section.

To provide a gear machining device and a gear machining method which achieve machining of tooth flanks having different torsion angles with high degree of accuracy. In a gear machining device, a side surface of a tooth of a gear includes a first tooth flank and a second tooth flank having a different torsion angle from the first tooth flank, a cutting blade of a machining tool has a blade traces having a torsion angle determined based on a torsion angle of the second tooth flank and an intersection angle between a rotation axis of a workpiece and a rotation axis of the machining tool so as to allow the second tooth flank to be machined on the pre-machined first tooth flank.

The invention relates to a milling tool for gear milling. The tool body is equipped with tangentially mounted milling inserts having four cutting edges and two holes, only one of which is utilized for a fixing screw in two of totally four index positions. By locating a screw hole in the seat of the milling insert at a distance from the radial support surface of the seat that is greater than the distance between an individual hole and a distal end of the milling insert, a clamping force is provided by means of the inherent elasticity of the fixing screw. In such a way, the milling insert is pressed against the radial support surface. By means of a transversal eccentricity, the milling insert is also pressed against a tangential support surface in the seat. By means of this construction, the two holes in differently long milling inserts can be formed with equally large distances from distal ends. Thereby, one and the same tool body can be equipped with differently long milling inserts.
