Publication number: 20240051042Abstract: A side milling cutter includes a main body extending along an axis from a first end with an interface for connection to a rotational drive to a free second end, receiving a bearing face for a disc-shaped cutter holder. The cutter holder is fastened to the second end and supported with a first main surface, facing the main body, on the bearing face, having an outer circumference projecting radially from the main body and a central through opening penetrating the cutter holder axially. Coolant feed channels feeding coolant to the second end are in the main body. Coolant distributing channels feeding coolant to the outer circumference of the cutter holder are in the cutter holder. At least two coolant distributing channels branch off from a common coolant distributing chamber between the main body and the cutter holder and into which at least two of the coolant feed channels open.Type: ApplicationFiled: January 31, 2022Publication date: February 15, 2024Inventors: Remus Venturini, Christian Göberl

Publication number: 20210308773Abstract: A turning tool holder includes a clamping portion for connection to a tool fitting of a machine tool and a machining portion having a seat for an interchangeable cutting insert. An internal coolant guide in the tool holder supplies coolant to the machining portion and has a first coolant inlet and first coolant outlet laterally of the seat. The first outlet has a bore laterally of the seat extending from a surface of the machining portion for receiving an interchangeable nozzle body with a shank region in the bore and a nozzle outlet region at an angle to the shank region on the machining portion surface. An internal coolant channel extends through the shank and nozzle outlet regions. The shank region has a periphery with a recess receiving a clamping element transverse to a longitudinal axis of the shank region fastening the nozzle body to the turning tool holder.Type: ApplicationFiled: June 27, 2019Publication date: October 7, 2021Inventors: MARTIN SENZENBERGER, REMUS VENTURINI, CHRISTIAN GOEBERL

Patent number: 9586271Abstract: A drill cutting insert has a cutting edge at a transition between a side surface and a top side which is formed with n identical cutting corners and n identical partial cutting edges —with n?{3, 4} —extending between the cutting corners. Each of the n partial cutting edges has: adjoining a first cutting corner, a main lip which is straight in plan view of the top side; adjoining the other cutting corner, a secondary lip which is straight in plain view of the top side, and a transition section, via which the main lip and the secondary lip merge into one another and which has a convex section adjoining the main lip and a concave section adjoining the secondary lip. The main and secondary lips enclose on the outside an angle a ?<180° in plan view of the top side.Type: GrantFiled: July 3, 2012Date of Patent: March 7, 2017Assignee: Ceratizit Austria Gesellschaft M.B.H.Inventors: Josef Prast, Remus Venturini, Uwe Schleinkofer

Patent number: 8702354Abstract: A cutting insert for a machining cutting tool. In a radial direction Q, which extends in a main plane H from the cutting corner to a center Z of the cutting insert, the following are formed in order: a falling cutting surface, a chip guiding stage base adjacent the cutting surface, a first chip guiding stage, which is adjacent to the chip guiding stage base and has a first surface rising from the chip guiding stage base and a first plateau adjacent thereto. A second chip guiding stage has a second surface rising from the first plateau and a second plateau adjacent thereto. A third chip guiding stage has a third surface rising from the second plateau and a third plateau adjacent thereto.Type: GrantFiled: September 30, 2010Date of Patent: April 22, 2014Assignee: Ceratizit Austria Gesellschaft m.b.H.Inventors: Uwe Schleinkofer, Remus Venturini

Patent number: 7374372Abstract: A polygonal indexable insert has cutting edges that run rectilinearly or in a curved manner in a plane perpendicular to a locating surface and that fall from cutting corners having acute angles to cutting corners with obtuse angles following one another alternately. The cutting edges have a rake face which first of all falls and then rises with a back region. The back region together with a center part of the indexable insert forms an intersection curve. The intersection curve lies at a distance a from the starting point of the associated cutting edge in the region of the cutting corners in each case at their intersection with the angle bisector. It is at a distance b from the end point of the associated cutting edge in the region of the cutting corners in each case at their intersection with the angle bisector. The distance b is greater than the distance a.Type: GrantFiled: September 11, 2007Date of Patent: May 20, 2008Assignee: Ceratizit Austria GmbHInventors: Rudolf Rofner, Harald Urschitz, Remus Venturini

Patent number: 7341433Abstract: A cutting insert includes a plurality of consecutively disposed, interlinked individual cutting inserts that can be brought into use successively through a respectively interposed predetermined breaking point by detaching a respectively preceding individual cutting insert in cutting use. The cutting insert has a blade-shaped construction with lower and upper bearing surfaces for being held in an elongated cutout with lower and upper opposing surfaces in a basic tool body of a grooving and cut-off tool or disk milling cutter. Each individual cutting insert is provided with a positioning device that cooperates with a complementary positioning device of the basic tool body. A grooving and cut-off tool or disk milling cutter and a wrench for the cutting insert, are also provided.Type: GrantFiled: August 9, 2006Date of Patent: March 11, 2008Assignee: Ceratizit Austria Gesellschaft m.b.H.Inventors: Dietmar Berger, Christian Göberl, Uwe Schleinkofer, Remus Venturini

Patent number: 7270503Abstract: The invention relates to a cutting tool for rotating and drilling into solid blocks, comprising a drill shank (1) and a cutting head (2) on one end. The cutting head (2) has a straight, front-face cutting edge (4) extending approximately crosswise in relation to the drill axis (3). The cutting head (2) also comprises a section (8) protruding from the shank of the drill (1) at a height (h) ranging from at least 5% to a maximum of 40% of the diameter (d) of the drill and at a width (b) ranging from at least 5% to a maximum of 40% of the diameter (d) of the drill. The section (8) comprises a straight, lateral cutting edge (5) which merges into a straight, rear-sided cutting edge (7) extending in an approximately parallel manner in relation to the front-faced cutting edge (4).Type: GrantFiled: August 12, 2003Date of Patent: September 18, 2007Assignee: Ceratizit Austria GES. m.b.H.Inventors: Dietmar Berger, Rudolf Rofner, Remus Venturini
