摘要

The fixture has a glass that is held between two very powerful magnets. The magnets enable to securely hold the glass on a base of a digital milling machine. A space of approximately 20 mm is utilized for passage of a cutting tool around the magnets. A set of surfaces is provided for the glass, where one of the surfaces is free for passage of the magnet and for cutting purposes. A suction cup is inserted in a recess in the base of the digital milling machine, where the cup prevents movement of the glass during cutting operations.
