The present invention relates to a positioning device for rotatably and rectilinearly positioning a card with respect to a treatment unit having an axis of treatment. The positioning device comprises a card holder for holding a card in a fixed position, wherein the card holder defines a virtual card surface plane coincident with the surface of a card facing the treatment unit once the card is placed in the card holder, and wherein the card holder defines a virtual card center point coincident with the intersection point of the axis of treatment and the virtual card surface plane. The positioning device further comprises a manipulator to which the card holder is attached, wherein the manipulator comprises: a cardanic element with a first axis of rotation and a second axis of rotation; and a virtual pivot point being the intersection of the first and the second axis of rotation.

A device for mechanically processing a workpiece is provided. The device includes a rotating device and a holding adapter which are mechanically intercoupled such that the rotating device generates a rotation of the holding adapter about a rotation axis, while the holding adapter holds a clamping part for the mechanical treatment of the workpiece such that the holding adapter rotation axis and a longitudinal axis of the clamping part enclose an angle of more than zero degrees.

A method for machining a workpiece which can prevent a reduction in machining accuracy and production efficiency. The method includes pressing a clamp part against a first portion of the workpiece, to clamp the workpiece in cooperation with a workpiece receiving part, causing the clamp part to move away from the first portion, to release the workpiece, which has been clamped by the clamp part, operating a robot to cause a robot hand to grasp a second portion of the workpiece, which is different from the first portion, to restrict the movement of the workpiece relative to the workpiece receiving part without a change in the posture of the workpiece, and operating a machine tool to machine the first portion while restricting the movement of the workpiece relative to the workpiece receiving part.
