    (54) Grinding head particularly for chamfering-profiling machines for glass plate elements


    (57) This grinding head particularly for chamfering-­profiling machines for glass plate elements comprises a supporting frame (10) which defines a cylindrical body (11) for accommodating and guiding a sleeve (12) which is axially slidable and rotatably supports the actuation shaft (13) of a grinder (14) which is rotated by a motor (19). The sleeve (12) may be moved with respect to the cylindrical body (11) so as to adjust the grinder position by virtue of a kinematic coupling (20, 22) extending between the sleeve and a control shaft (21), which is substantially parallel to the sleeve. The control shaft (21) is fixed in an axial direction and is rotated about its own axis by a positioning motor (30) controlled by a control and adjustment unit (40).
