It comprises two units for machining by copying (1a; 1b) arranged on either side of a component (3) so that two opposite faces (3a; 3b) of the component (3) may be machined simultaneously. An abrasive strip (2a; 2b) is stretched around four wheels (4a, 5a, 6a, 7a; 4b, 5b, 6b, 7b), one (4a; 4b) of which is rotationally driven. A bar (8a; 8b) mounted to slide perpendicular to the face to be machined (3a; 3b) supports two of the wheels (5a, 7a; 5b, 7b) and it is guided in this direction perpendicular to the face to be machined (3a, 3b) by a roller (10a; 10b) pressed by a dual-acting thrust cylinder (11a; 11b) onto a template (13a; 13b). The displacement of the bar (8a; 8b) parallel (F1) to the length of the face (3a; 3b) to be machined is provided by a slide (9a; 9b). <IMAGE>
