20080253847 | Adjustable Machine Tool Cutting Insert Holder Apparatus - An adjustable threading tool assembly. A cutting insert holder is adjustably held in a pocket in a toolholder. The cutting angle of the insert can be set by selecting a precision ground washer that sets the position of a retaining bolt that holds the insert in the pocket such that the desired angle is provided. | 10-16-2008 |
20090087268 | Tool Holder System - In a tool holder system having a base support plate ( | 04-02-2009 |
20100189520 | Cutting Tool Having a Clamping Mechanism - A clamping mechanism includes a male portion and a female portion. The male portion has a forwardly extending locking protrusion, and an alignment protrusion extending forwardly of the locking protrusion. A rear of the female portion has a forwardly extending locking bore and an alignment bore extending forwardly from a front end of the locking bore. The locking bore has an insertion bore portion which merges with a gripping bore portion. The insertion bore portion has an insertion bore axis while the gripping bore portion has a gripping bore axis that is spaced apart by a non-zero first distance from the insertion bore axis. In a clamped position, the alignment protrusion abuts a portion of the alignment bore and the locking protrusion abuts the gripping bore portion along a gripping angular extension, thereby forming a circumferential interference fit. | 07-29-2010 |
20100254774 | Cutting Tool Assembly and Tool Holder Therefor - A cutting tool assembly for boring and internal grooving operations includes a tool head having a removably secured cutting insert at a forward insert receiving end and a rear mating end with a male or female type tool holder coupler in the form of an engagement protrusion or cutting holder receiving pocket. The tool head is fixed to a tool holder with a front mating end having a female or male tool head coupler in the form of a tool head receiving pocket or engagement protrusion. Following assembly, at least three abutting wall surfaces and an adjacent support surface of the tool holder coupler are in contact with at least three non-coplanar abutment surfaces and an adjacent supporting surface of the tool head coupler, respectively, and a fastening screw member extends through a through bore in the tool holder coupler engaging a threaded screw bore in the tool head coupler. | 10-07-2010 |
20110110732 | Cutting Tool Assembly - A cutting tool assembly includes an exchangeable adapter releasably secured to a holder. The adapter is provided with a side plate. In a bottom view of the holder, a portion of a front surface of the holder adjacent a first side surface of the holder forms an internal acute angle α with the first holder side surface and in a bottom view of the adapter, a rear surface of the adapter side plate forms the acute angle α with an inner side surface of the adapter. | 05-12-2011 |
20130034393 | Modular Cutting Tool Holder and Clamping Mechanism Therefor - A modular cutting tool holder portion for a metal-working machine includes a first engagement face configured for clamping engagement with a corresponding second engagement face of a complementary modular cutting tool holder portion. The first engagement face includes a base surface and interlocking elements in the form of exactly four projecting protrusions or exactly four recesses. Each interlocking element includes a non-contact surface spaced from the base surface. The non-contact surface includes two opposing edges between which it extends, and two abutment surfaces each extending from a respective one of the two opposing edges to the base surface and being configured for the clamping engagement. | 02-07-2013 |
20130279995 | Cutting Tool Assembly With Removable Tool Head - A cutting tool assembly has a tool holder, a tool head and a tool head fastening member. The tool holder includes holder front and top ends, with a holder mating surface extending therebetween. A holder clamping portion is located rearwards from the holder mating surface. The tool head has a tool head bottom end provided with a tool head mating surface. A tool head clamping recess extends upwards from the tool head bottom end, rearwards from the tool head mating surface. In an assembled position of the cutting tool assembly, the tool head mating surface forms a dovetail connection with the holder mating surface, and the tool head fastening member clamps the tool head clamping recess, thereby externally clamping the tool head to the tool holder. | 10-24-2013 |
20130294854 | CUTTING TOOL ASSEMBLY - A cutting tool assembly has a cutting insert, an insert holder and a tool shank. The insert holder has an insert receiving slot, a plurality of through holes and first and second recesses. Clamping screws pass through the through holes. The first and second recesses are located at an edge of a rear surface of the insert holder and are opposed to each other relative to an orientation of the slot. The tool shank has a plurality of threaded holes and first and second flanges. The clamping screws engage the threaded holes. The first and second flanges are opposed to each other and engage the first and second recesses, respectively. The insert holder is removably mounted to the tool shank by the clamping screws. The through holes are offset from the threaded holes when the insert holder is mounted to the tool shank. | 11-07-2013 |
20150336177 | DIAMOND TIP CUTTING TOOL - A diamond tip cutting tool adapted to be positioned in a cutter includes a polycrystalline diamond (“PCD”) chip and a cartridge defining an opening. The opening is adapted to receive the PCD chip. A wedge clamp is removably coupled to the cutter to secure the PCD chip in the opening. | 11-26-2015 |
