  • Patent number: 11806791
    Abstract: A tool system for machining includes a tool body that has a first end for connecting to a machine tool and a second end having an end face on which a seat for an interchangeable cutting insert is formed. The cutting insert has an underside formed as an abutment surface, a top side formed as a rake face, and an encircling side face formed as a flank, and a cutting edge is formed at a transition from the top side to the encircling side face. The cutting insert is arranged on the seat such that the top side extends perpendicularly to the longitudinal axis of the tool body and the cutting edge protrudes beyond the outer circumference of the end face of the tool body in a radial direction with respect to the longitudinal axis with two usable cutting corners and cutting-corner portions adjoining the latter on both sides.

  • Patent number: 11745269
    Abstract: A peeling plate has upper and lower sides, lateral faces extending between the upper and lower sides, and primary and secondary cutting edges at the transition from the lateral faces to the upper side. The peeling plate in a plan view of the upper side has the shape of a substantially regular n-gon, n being five or six, and n lateral edges lying between the n lateral faces. A primary cutting edge and a secondary cutting edge are formed at the transition from at least one lateral face to the upper surface, wherein active primary cutting edges and active secondary cutting edges are spaced apart from a lateral edge. The lateral edge at the transition to the upper side forming an active cutting corner to the respective active primary cutting edge and active secondary cutting edge.

  • Publication number: 20230015428
    Abstract: A tool system includes a machine-proximal shank configured to be introduced into a driven tool receptacle and containing a device for transferring a rotating movement to be picked up from the driven tool receptacle. A tool-proximal shank is configured as a tool holder or to have a tool holder releasably connected thereto. A gear mechanism disposed between the machine-proximal shank and the tool-proximal shank is configured to transfer a rotating movement transmitted by the device in a reduced manner to the tool-proximal shank. At least one insert seat configured on the tool holder for receiving an interchangeable cutting insert is provided on an end face of the tool holder extending transversely to a longitudinal axis of the tool holder. A method for machining a workpiece is also provided.

  • Patent number: 7374372
    Abstract: 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.
