    摘要: A cutting tool used for grooving and turning operations where a cutting insert is releasably securable in a tool holder. The cutting insert includes insert upper and lower surfaces, at least one of which includes an insert engagement arrangement having two converging insert engagement wedge surfaces. The tool holder includes an insert receiving slot having a clamping jaw surface and a base jaw lower surface, at least one of which includes a slot engagement arrangement having two converging slot engagement wedge surfaces. When assembled, the cutting insert is releasably clamped in the insert receiving slot. The at least one insert engagement arrangement abuts the at least one slot engagement arrangement only at the insert engagement wedge surfaces and the slot engagement wedge surfaces.

    摘要: A cutting tool includes a two-way indexable cutting insert clamped in a transversely oriented insert receiving pocket of an insert holder. The insert holder includes a forwardly located insert mounting portion that includes upper and lower jaws which together define the insert receiving pocket having a pocket front opening. The lower jaw includes a pocket lower clamping surface. The upper jaw includes a pocket upper clamping surface which faces mutually towards the pocket lower clamping surface and a pocket stopper surface facing generally towards the pocket front opening. The pocket stopper surface is closer to the pocket lower clamping surface and further from the pocket front opening, than the pocket upper clamping surface. The pocket stopper surface is further from the pocket rear opening than the pocket lower clamping surface.

    摘要: A cutting insert includes opposing insert first and second side surfaces. The insert first side surface includes a first mounting arrangement. The first mounting arrangement includes a) at least one first side abutment surface facing away from the insert second side surface, b) a first stopper abutment surface oriented transversely to the at least one first side abutment surface and c) two opposite-facing first wedge abutment surfaces oriented transversely to the at least one first side abutment surface and converging forwardly. An insert holder has a corresponding pocket mounting arrangement for engagement with the first mounting arrangement.

    摘要: A double-ended parting cutting insert. The cutting insert includes two cutting portions at opposite ends thereof which are oriented at 90° to each other. The cutting insert includes a pair of rake and support engagement grooves, the rake and support engagement grooves of each one of the pair converging in a direction away from a respective cutting portion. An insert holder includes a clamping portion having a resilient upper clamping jaw having an upper engagement ridge and a lower base jaw having a lower engagement ridge. A gap therebetween forms an insert receiving slot that has a slot opening. The upper and lower engagement ridges converge in a direction away from the slot opening. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the cutting insert is located in the insert receiving slot and resiliently clamped therein.

    摘要: A slotting tool body includes a disc-like cutter portion including opposing forward and rearward cutter portion side surfaces and a cutter portion peripheral surface extending therebetween and a shank portion projecting rearwardly from the rearward cutter portion side surface. The cutter portion includes a number N of angularly spaced apart clamping portions, each having a peripherally disposed insert receiving slot. The cutter portion further includes a flexibility recess recessed in the forward cutter portion side surface and extending to each of the insert receiving slots. A cutting insert is releasably and resiliently clamped in each insert receiving slot to form a rotary slot cutting tool.
