摘要： A toolholder for holding a cutting insert, particularly for grooving and/or parting operations. The toolholder comprises a base and a clamping arm forming therebetween a pocket and a slot. The pocket is open at a front end thereof for receiving the cutting insert, and the slot extends rearwardly from a rear end of the pocket. A fastening screw extends through the slot from the clamping arm to the base for displacing the clamping arm toward the base in order to clamp the cutting insert within the pocket. A spacer is disposed in the slot for limiting an extent of movement of the clamping arm toward the base, thereby preventing overclamping of the clamping arm.

摘要： A metal-cutting tool comprises a holder, a clamp, and a metal-cutting insert. The holder includes a blade part which forms an upwardly facing seating surface extending in a front-to-rear direction. The holder includes a recess including a longitudinal axis extending in the front-to-rear direction at an angle relative to the seating surface, whereby an imaginary rearward extension of the seating surface converges toward the axis. The insert is mounted on the seating surface and the clamp has a rear portion which is slidable within the recess, whereby a front portion of the clamp pushes downwardly and rearwardly against a top surface of the insert. That top surface is shaped so that the front portion of the clamp is flexed upwardly relative to the rear portion when the rear portion is pushed rearwardly to the clamping position.

摘要： A tool includes a tool body and a cutting portion detachably mounted thereon, the tool being rotatable about a longitudinal center axis. The tool body includes flutes formed in an outer surface thereof, and a pair of forward projections at a front end thereof. The cutting portion includes front flutes formed in an external side thereof, and a pair of recesses extending circumferentially in communication with respective ones of the front flutes. To connect the cutting portion to the tool body, the cutting portion and tool body are converged longitudinally so that the projections enter the front flutes. Then, relative rotation is produced between the cutting portion and tool body to align the front flutes with the rear flutes while causing the projections to enter the recesses and form therewith a bayonet coupling.

摘要： A cutting tool assembly comprises a tool shank having a shank holding portion and an exchangeable adaptor. The adaptor has an adaptor mounting portion to be secured to the shank holding portion with clamping means, and an insert retaining portion for retaining a replaceable cutting insert, the insert retaining portion projecting outwardly from the adaptor mounting portion. The adaptor mounting portion has a side wall formed with a protrusion which has a protrusion abutting surface substantially parallel to the side wall. The shank holding portion has a face surface generally parallel to the side wall of the adaptor mounting portion and formed with a recess mating with and capable of receiving the protrusion of the adaptor mounting portion. The clamping means comprises an adaptor through bore formed adjacent a rear end of the adaptor and passing through the protrusion, a threaded bore formed in the shank holding portion and aligned with the adaptor through bore, and a clamping screw. The rear end of the adaptor is formed with a transverse slit merging with the adaptor through bore, and at least a portion of the through bore, which is disposed in the protrusion, tapers in the direction towards the protrusion abutting surface of the adaptor mounting portion, the screw head portion being capable of bearing against the tapered portion of the through bore.

摘要： Slot or track milling tool device wherein a number of inserts having an insignificant axial extension are arranged in seats at the peripheral portion of an essentially disc shaped tool holder body. The inserts, being of a per se known kind, have at least one abutment face arranged obliquely relative to the insertion direction of the insert. The abutment face in contact with an abutment portion at each seat of the tool holder body. Each such abutment portion being a tongue shaped portion integral with the tool holder body. For each tongue shaped portion, there is arranged a rotatable clamping device having a surface arranged in a cam or eccentric fashion. The rotatable clamping device is intended to displace the tongue shaped portions so that an abutment point thereon reaches an engagement with and remains in engagement with the obliquely rearwardly facing engagement surface of the insert.

摘要： A metal-cutting insert for performing cut-off and grooving operations and of the so-called self-gripping type. The insert comprises a front end with a cutting edge, first and second elongated straight grippable surfaces extending in converging relationship rearwardly from the front end and a rear end defined by first and second straight surfaces of approximately equal length that intersect each other in an included obtuse angle. The grippable surfaces each have a concave transverse contour. The first and second end surfaces extend respectively from the first and second grippable surfaces and intersect at a location to coincide with the intersection of a rear locating surface and a key-receiving aperture of a support blade when the insert is fully received within the support blade recess.

摘要： A throw away cutting tool comprising a holder formed with a wedge groove and a throw away insert having a cutting edge at one end thereof and a wedge portion at the other end, the wedge portion being adapted to be clamped in the wedge groove by elasticity of the material of the holder. The holder is at least partly made of cemented carbide for higher rigidity and cutting stability. Also, the radius of curvature at the deep end of the wedge groove is optimized for crack resistance. Further, the angle of the V-ridge on the holder is interrelated to the angle of the V-groove in the insert for more holding stability and crack resistance.
