Abstract:
1. A machine tool with a base member ( 12 ), with at least one pocket ( 24 ) formed in the base member ( 12 ) and with at least one cutter carrier ( 20 ) carrying a cutting insert ( 18 ), wherein the cutter carrier ( 20 ) lies with two side surfaces ( 30 , 32 ), enclosing an angle with one another, against a respective side supporting surface ( 34 , 36 ) and with its bottom ( 38 ) against a bottom supporting surface ( 40 ) of the pocket and is releasably clamped in the pocket ( 24 ) by a clamping element ( 28 ), and wherein the cutting insert ( 18 ) protrudes with an effective cutting edge ( 23 ) in the outward direction beyond the cutter carrier ( 20 ) and the base member ( 12 ), wherein the bottom supporting surface ( 40 ) forms a wedge surface, which is arranged on an adjusting member ( 58 ) that is displaceable with respect to the base member ( 12 ) along an axis of displacement ( 56 ) and encloses an acute angle with the axis of displacement ( 56 ) and against which the cutter carrier ( 20 ) lies with its bottom ( 38 ) formed as a complementing wedge, and wherein the two side supporting surfaces ( 34 , 36 ) form guiding surfaces for the cutter carrier ( 20 ), aligned substantially perpendicularly in relation to the axis of displacement ( 56 ) of the adjusting member ( 58 ), during a displacing operation performed by displacement of the adjusting member ( 58 ), characterized in that, on a third side surface ( 42 ), the cutter carrier ( 20 ) forms a wedge surface ( 44 ), which encloses a respective angle with the two side surfaces ( 30 , 32 ) lying against the side supporting surfaces ( 34 , 36 ) and with the bottom ( 38 ) and against which there lies a complementing wedge ( 46 ) of the clamping element ( 28 ) that can be displaced in relation to the base member ( 12 ) by an adjusting member ( 48 ) while exerting a clamping force extending in the direction of the two side supporting surfaces ( 34 , 36 ) and the bottom supporting surface ( 40 ) and the axis of displacement ( 56 ) of the adjusting member ( 58 ) is aligned parallel to an axis of rotation ( 10 ) of the base member ( 12 ).
