ABSTRACT:
A workpiece holder, particularly adapted for holding eyeglasses lenses (L), comprises a support (12) on which there are arranged two clamps (14, 17, 117) for clamping each a portion of a lense. Each clamp defines an axis (A) which is substantially perpendicular to the portion of lense clamped thereby. Each clamp is positionable and lockable with said axis (A) oriented in any direction at the interior of an ideal cone (A1 - A2) having a vertex through which the said axis (A) is passing. Positioning means (3, 4, 40) are provided for displacing the said support (12) along a horizontal plane with respect to a fixed tool (28).
