<p>A device for drilling or boring openings, primarily deep openings, comprises a cutter head (1) with guides (5), (6), said head being equipped with a device (7) for displacing the cutter (8) in the radial direction from the drive (10). The input of the drive (10) is connected via a control signal transmission circuit (21) and a transducer (20) to the output of a system (19) for digital programming control (DPC). A sensor (15) for checking variations in the wall thickness of the component, a sensor (16) of the angle of rotation of the component, a sensor (17) of the angle of rotation of the cutter head (1) and a sensor (18) for checking the wobbling of the component (22) are connected to the DPC system (19). The drive (10) of the device (7) for displacing the cutter (8) in the radial direction is in the form of a linear drive and is mounted on the cutter head (1). The technical result is expressed in an increase in the accuracy of machining deep openings while ensuring that said openings can be corrected during the process of machining the openings.</p> |
