Patent number: 10875099Abstract: A turning tool holder with a turning tool holder shank and a turning tool holder head is described. In an installed position of the turning tool holder, a longitudinal extension direction of the turning tool holder head is a longitudinal extension direction of the turning tool holder shank which continues straight-ahead, at an angle, or over a radius. The turning tool holder head, seen in its longitudinal extension direction, thereby has two side faces, wherein a lateral coolant outlet is provided on one of the side faces, the lateral coolant outlet center axis of which lateral coolant outlet, in plan view, is predominantly oriented along the longitudinal extension direction of the turning tool holder head. In addition, a turning tool with such a turning tool holder is presented.Type: GrantFiled: January 14, 2019Date of Patent: December 29, 2020Assignee: KENNAMETAL INC.Inventors: Igor Kaufmann, Sathish Kumar Nagarajan, Manoj Krishnamoorthy, Anwar Sadat Mohideen Abdul

Patent number: 10300532Abstract: A clamp for a tool holder is disclosed. The clamping tool holder includes a body having an insert-receiving pocket and a threaded clamp-receiving bore with a coolant opening for receiving pressurized coolant from a coolant source. A clamp includes a threaded aperture extending from a top surface to a bottom surface and coolant passages in fluid communication with a coolant header. A clamp screw is threaded into the threaded aperture of the clamp. The clamp screw includes a plurality of coolant passages in fluid communication with the coolant opening of the body, and at least one coolant channel in fluid communication with the coolant passage. Coolant from the coolant source enters the coolant opening of the body, travels into the clamp screw, travels into each coolant passage of the clamp, and then exits the clamp in a direction toward a cutting insert-workpiece interface.Type: GrantFiled: June 26, 2017Date of Patent: May 28, 2019Assignee: KENNAMETAL INC.Inventors: Shi Chen, Qi Wang, Igor Kaufmann, Jason Won Goldsmith, Yingwei Wu

Publication number: 20190099811Abstract: A cutting insert includes a tool carrier having a body with a pocket, and a cutting tip affixed to the pocket by brazing. The pocket is defined by a vertical back wall and a horizontal support surface. A notch is formed at the intersection between the vertical back wall and the horizontal support surface. The notch has a non-planar first portion proximate the vertical back wall and formed with a radius, R1, and a planar second portion extending between the first portion and the horizontal support surface and formed at an inclination angle with respect to a plane parallel to the horizontal support surface of the pocket. The design of the notch significantly reduces thermal stress and eliminates the formation of cracks in the pocket of the tool carrier when using an injection molding process to form the tool carrier.Type: ApplicationFiled: October 2, 2017Publication date: April 4, 2019Applicant: Kennametal Inc.Inventors: Qi Wang, Neal Myers, Shi Chen, Igor Kaufmann
