The invention relates to a machine tool for use in tool machines, comprising a cutting element which is preferably configured as a cutting ring and at least two insert seats that are provided in the cutting element at distance to each other in the circumferential direction. The insert seats are fitted with at least one group of at least two identical insert tips that are detachably arranged therein and that have one working edge each, the effective working edges of the insert tips of one group being cut to the same nominal size. The insert tips are configured as indexable inserts, every single indexable insert of a group being associated with a defined insert seat in all possible positions of adjustment, and the indexable inserts of a group having at least two working edges each, one of these edges being always in the effective and at least one other edge being in the ineffective position, depending on the position of the indexable inserts in the associated insert seats. The indexable inserts of a group assume identical positions of adjustment in which defined working edges of every indexable insert of a group have the same orientation in the associated insert seat, the working edges of the indexable inserts of a group being cut to a nominal size in all common positions of adjustment.
A machine tool for use in tool machines, comprising a cutting body (12), which is preferably realized as a cutting ring, at least two plate seats (16, 44) at a distance from one another in the circumferential direction in the cutting body, at least one group of at least one insert plate (18, 42) that is detachably arranged in the plate seats and that has at least one working edge (1 to 4), the at least one working edge of the at least one insert plate of a group being ground to a predefined nominal size, characterized in that the insert plates are realized as reversible plates (18, 42), each individual reversible plate of a group is assigned to a defined plate seat (16, 44) in all positions of change, the reversible plates of a group each have at least two working edges (1 to 4, 1′ to 4′), of which, depending on the position of the reversible plates in the associated plate seats (16, 44), in each case one is in an operative position and at least one other is in a non-operative position, all reversible plates of a group having a plurality of reversible plates assume mutually corresponding positions of change, in which defined working edges (1 to 4, 1′ to 4′) of each reversible plate (18, 42) of the respective group have the same orientation within the associated plate seat (16, 44), and the working edges (1 to 4, 1′ to 4′) of the reversible plates of a group are ground to nominal size in all common positions of change.
A cutting ring for a machine tool, comprising at least two plate seats (16, 44) at a distance from one another in the circumferential direction, and at least one group of at least two insert plates of like realization that are detachably arranged in the plate seats and that each have at least one working edge, the working edges of the insert plates of a group being ground to the same nominal size, characterized in that the insert plates are realized as reversible plates (18, 42), each individual reversible plate (18, 42) of a group is assigned to a defined plate seat (16, 44) in all positions of change, the reversible plates (18, 42) of a group each have at least two working edges (1 to 4, 1′ to 4′), of which, depending on the position of the reversible plates in the associated plate seats (16, 44), in each case one is in an operative position and at least one other is in a non-operative position, all reversible plates of a group having a plurality of reversible plates assume mutually corresponding positions of change, in which defined working edges (1 to 4, 1′ to 4′) of each reversible plate (18, 42) of the respective group have the same orientation within the associated plate seat (16, 44), and the working edges of the reversible plates of a group are ground to nominal size in all common positions of change.
