Abstract

An apparatus for sharpening objects (2) comprises abrading means (6) arranged for abrading an end portion of said objects (2) and for creating tip means (2a) in said objects (2) and support means (7) connected to rotation driving means (8) and arranged for supporting said abrading means (6), said abrading means (6) being fixed to said support means (7) by magnetic coupling means (15); the projection of the longitudinal axis of each object (2) on a plane containing an active surface (10) is tangent to a circumference the center of which lies on a rotation axis (X) of said abrading means (6); moving means (33) for moving said objects (2) are provided, the moving means (33) being arranged for driving said objects (2) to interact with regions of said active surface (10); in addition, transfer means (5) rotates each object (2) around the longitudinal axis thereof and moves each object (2) along said longitudinal axis towards said abrading means (6).
