The invention relates to a boring head ( 100 ), comprising at least one guide element ( 140 ), arranged on the periphery thereof, and at least one cutting insert ( 150 ), also arranged on the periphery, whereby the guide elements ( 140 ) as well as the at least one cutting insert ( 150 ) are supported by cassettes ( 200, 205 ) which are guided in grooves ( 160, 165 ) in a sliding manner. Said boring head is characterized in that an adjustment means ( 400; 410; 460; 470 ) is provided for adjusting and aligning the projecting end of both the at least one guide element ( 140 ) and the at least one cutting insert ( 150 ) on the periphery of the boring head housing ( 110 ). Said adjustment means is adjacent to the cassettes ( 200; 205 ), on the sides thereof which are opposite to the at least one guide element ( 140 ) or to the at least one cutting insert ( 150 ). The shape of the adjustment means, in the peripheral direction, is adapted to the radial distance between the cassettes ( 200; 205 ) and the axis of symmetry of the boring head ( 100 ), so that the projecting end of both the guide elements ( 140 ) and the at least one cutting insert ( 150 ) is adjusted and aligned simultaneously with the mounting of the adjustment means ( 400; 410; 460; 470 ) on the boring head ( 100 ). |
