Patent number: 7641422Abstract: A cutting tool for parting and grooving operations of the kind including a coupling part, which is intended for mounting the cutting tool in a machine tool, and a tool head detachably connected to the coupling part. The tool head includes a basic holder part and, joined to the basic holder part, a blade part, in front portion of which an insert pocket is formed, in which a cutting insert is fastenable. The cutting tool also includes means for supplying cooling agent to the cutting insert. The cooling agent supplying means includes a tube member, which is mounted in a recess, which is transverse to the longitudinal direction of the blade part and arranged in the tool head. The tube member has an inlet for connection to a cooling agent source and an outlet for leading the cooling agent in a direction towards the cutting insert.Type: GrantFiled: February 22, 2005Date of Patent: January 5, 2010Assignee: Sandvik Intellectual Property ABInventors: Erik Berminge, Per Hansson

Patent number: 7419337Abstract: A parting blade having a flat, elongate body, which is delimited by two opposite side surfaces and has two opposite longitudinal edges which are mutually parallel and present chamfered surfaces for wedging the body in a holder, and which includes at least one insert seat formed adjacent to an end, the position of which seat in relation to a longitudinal edge determines the tip height of a turning insert mounted in the insert seat. An attachment part is formed on one of the side surfaces of the blade body. The attachment part is shorter and thinner than the proper blade body and has two opposite longitudinal edges which are mutually parallel and present chamfered surfaces for wedging the attachment part in another holder. In this way, the parting blade can be formed for robust, wide turning inserts and in spite of this be mounted in holders intended for considerably thinner parting blades.Type: GrantFiled: May 1, 2006Date of Patent: September 2, 2008Assignee: Sandvik Intellectual Property ABInventor: Erik Berminge

Publication number: 20080038072Abstract: In a first aspect, the invention is related to a cutting tool for parting and grooving operations of the kind comprising a coupling part (1), which is intended for mounting the cutting tool in a machine tool, and a tool head (2) detachably connected to the coupling part. The tool head comprises a basic holder part (8) and, joined to the basic holder part, a blade part (9), in the front portion of which an insert pocket is formed, in which a cutting insert (11) is fastenable. The cutting tool also comprises means for supplying cooling agent to the cutting insert. Characterizing for the invention is that said cooling agent supplying means include a tube member (24), which is mounted in a recess, which is transverse to the longitudinal direction of the blade part (9) and arranged in the tool head (2), the tube member having an inlet for connection to a cooling agent source and an outlet for leading the cooling agent in a direction towards the cutting insert (11).Type: ApplicationFiled: February 22, 2005Publication date: February 14, 2008Inventors: Erik Berminge, Per Hansson

Patent number: 7264424Abstract: A tool head, which is adapted to receive a cutting insert for chip removal machining, includes a basic holder which has a lower support part and an upper clamping portion defining therebetween and insert-receiving pocket. A slot extends through the basic holder at a location spaced from the pocket, wherein the clamping portion is joined to a remaining portion of the basic holder by a hinge portion about which the clamping portion is elastically displaceable toward the cutting insert. A recess extends through the basic holder parallel to the slot and in communication therewith for receiving a nut roll. A clamping screw extends through a bore of the basic holder and into engagement with the nut roll, wherein the clamping screw is operable to displace the nut roll into the slot to expand the slot and thereby elastically displace the clamping portion about the hinge and toward the cutting insert.Type: GrantFiled: November 19, 2004Date of Patent: September 4, 2007Assignee: Sandvik Intellectual Property ABInventors: Per Hansson, Erik Berminge
