Abstract:
A machining apparatus includes at least one tool holder (1) and at least one cutting tool (2) that are detachably interconnected. At least one first marking (7a) is provided on the tool holder (1) and at least one further marking (7b) is provided on the cutting tool (2). When connecting the tool holder (1) to the cutting tool (2), they can be aligned with each other with the aid of the markings (7a, 7b). The machining apparatus is preferably used for machining spectacle lenses, especially progressive lenses.

Abstract:
In a method of machining a blank or a semifinished product (1) of a subsequent optical element, in particular an eyeglass lens, the blank or the semifinished product (1) is held on a surface (5) of a mounting device (3) for machining the free side of the blank or the semifinished product (1). The mounting device (3) is inserted into a holding device. An adhesive connection is introduced between the blank or the semifinished product (1) and the mounting device (3), the mounting device (3) being adapted to the radius of that surface (5) of the blank or of the semifinished product (1) which is connected to the mounting device (3).
