A bevel gear manufacturing face cutter head (2) for face hobbing and face milling wherein the cutter head includes positive blade seating surfaces (16, 18) and the capability to clamp the blades (8) tight to the positive seating surfaces and to adjust the cutting blades radially after they are pre-clamped and axially located.

A clamping device is configured to clamp a cutting insert onto a holder of a cutting tool. The clamping device contains a clamping bolt and a locking bolt, wherein the clamping bolt is configured to be inserted into each of the cutting insert and the holder. The locking bolt is configured to be inserted into the holder, such that the locking bolt pre-strains the clamping bolt into clamping the cutting insert onto the holder. The clamping bolt is configured rotatable about a longitudinal clamping axis of the clamping bolt relative to each of the cutting insert and the locking bolt, such that the clamping bolt wedge engages with the locking bolt during a clamping bolt rotation about the longitudinal clamping axis.

In one embodiment, a holder includes a body part elongated from a first end part to a second end part along a rotation axis. The body part includes a first member, a second member, and a third member. The first member is located on a side of the first end part, and includes a pocket to receive a cutting insert. The second member is located closer to the second end part than the first member, and includes at least one cavity inside the second member. The third member is located closer to the second end part than the second member.

In a circular cutting insert of the present invention, the upper side surface and the lower side surface each include: a plurality of planar restraining faces which are disposed sequentially in a circumferential direction of the upper side surface and the lower side surface so as to interpose a joint portion between each of the planar restraining faces and each have a side disposed on the side surface-intermediate line (N); and a plurality of antivibration restraining faces which are each disposed between two planar restraining faces adjacent through the joint portion and each include an inclined face, and the restraining faces of the lower side surface are disposed so as to be shifted with respect to the restraining faces of the upper side surface by a predetermined angle () around a central axis of a screw insertion hole.

A cutting tool comprising a cutting tool holder and a cutting insert adapted to be mounted thereon. The tool holder comprises an insert seat defined by a base and at least one side wall extending from the base to define an insert seat space adapted to receive therein the insert. The seat comprises a support element extending into the insert seat from the base, and a fastening member engageable with the seat. The fastening member is displaceable with respect thereto between a mounting position adapted to allow the insert to be mounted onto the seat and a securing position adapted for securing the insert within the seat. The insert is formed with a securing cavity and when the insert is mounted onto the tool holder and is in the securing position, a portion of the support element and the fastening member is received within the cavity of the insert.

A cutting tool includes a replaceable cutting insert and a tool body. The tool body includes a tool body surface and an insert pocket recessed therein. The cutting insert is releasably retained in the insert pocket. The tool body includes at least one coolant duct that has an outlet orifice that opens out in a coolant chamber. The coolant chamber is bounded on a side opposite the outlet orifice by a coolant deflection portion that is integrally formed with the tool body in a unitary one-piece construction and at least partially overhangs the outlet orifice in a direction towards the insert pocket. The coolant deflection portion has a chamber deflection surface configured to deflect a coolant in the direction of a cutting edge of a cutting insert seated in insert pocket.

A cutting tool includes a generally cylindrical tool body disposed about a central longitudinal axis, the tool body having first and second extending sides with respective first and second bores that pass therethrough, wherein a first longitudinal axis of the first bore and a second longitudinal axis of the second bore are configured to be non-parallel to a horizontal axis of the tool body that is perpendicular to the central longitudinal axis of the tool body. The cutting tool also includes a replaceable cutting insert configured to be removably attached to the tool body and first and second attachment elements configured for receipt in the first and second bores, respectively, and adapted to engage the cutting insert and secure the cutting insert to the tool body.

A cutter head (4, 6) having a lock spring (30) utilized with an adjustment screw (16) for preventing the adjustment screw from loosening during machining. Once positioned by turning the adjustment screw, a cutting blade (8) will not change position in a mounting slot (10) due to a loosening adjustment screw.

A method for assembling cable wrapping tapes. From an adhesive tape parent roll, strip-like adhesive tapes (11), each having two cut edges (12a) on the sides, are produced from a textile material which has an adhesive coating (12) on one side, by cutting in the drawing direction of the parent roll. The cutting is performed using an ultrasound-excited cutting tool (1) and wherein the cutting is performed using a cooled cutting tool (1). An adhesive tape (11), having a strip-like textile carrier material (13) and an adhesive coating (12) applied to one side and two cut edges (12a) on the sides. The cut edges (12a) are created by ultrasound cutting, and the textile carrier material (13) of the carrier is fused to its cut edges (12a). No adhesive coating (12) exists on the cut edges (12a); which are free of lint and threads.

A cutting tool assembly has a cutter body, a clamp pin, a cutting insert and a set screw. The clamp pin is inserted to the cutter body to secure the cutting insert to an insert pocket. The set screw is fastened to a threaded hole of the cutter body to press the clamp pin toward the insert pocket. A side surface of the cutting insert contacts a side wall of the insert pocket at a first contact portion. A head of the clamp pin contact an inner peripheral surface of a bore of the cutting insert at a second contact portion. The first and second contact portions are located such that a moment acts on the cutting insert toward the base wall of the insert pocket around the first contact portion.
