Abstract (en)

[origin: EP0657248A1] The invention discloses a lapping head comprising a casing (22), supporting a plurality of lapping wheels (124; 224), supported by a central shaft (2) connected with a driving element (50) and containing bevel pinions (13) caused to rotate by kinematic elements. Each of said lapping wheels (124) is attached to the end (123) of a pivot (122), eccentrically connected in the hole (16) of one of said bevel pinions (13), provided with a spheric body (125) suited to allow, during the rotating motion the rotation of said lapping head, a conic motion of revolution of the longitudinal axis (129) of said pivot (122) and of the lapping wheel attached to it in relation to the longitudinal axis of the corresponding bevel pinion (13), and a simultaneous motion of revolution of said lapping wheel in relation to the axis of rotation (100) of the lapping head itself. <IMAGE>
