<p>A process for producing conical bores on a work piece by means of a honing tool (1) which has a central carrying body (2) and is arranged, by means of said body, on the spindle (41) of a honing machine. Said process makes possible the production of continuously smooth cone surfaces by the honing surfaces being guided, essentially on spiral paths, in accordance with the predetermined cone inclination until the predetermined cone profile has been achieved. The average cutting speed is held at an essentially constant value by a computer-aided control of the displacement speed, of the speed of widening in the radial direction and the circumferential speed. A honing tool which is particularly suitable for carrying out the process has, distributed symmetrically on the carrying body (2), segments (5) which are mounted such that they can pivot in radial planes, carry radially outwardly pointing honing elements (20) and the pivoting movement of which can be controlled by means of a widening device (21). As drive of the widening device (21) there is provided a push rod (48), extending through the honing spindle (41), designed as hollow shafts, and drive rod (42), with a circulating-ball-screw mounting (50) in the region of the drive by an electric motor (56) and a reduction gear mechanism (52). <IMAGE></p> |
