Abstract (en)
[origin: EP0366506A1] The device comprises, for the machining of each bearing surface (2, 3) of the workpiece (1), three blocks (13, 16a, 16b) for applying abrasive, one of which is mounted in a fixed position on the arm (7) and the two others are mounted on two jaws (14a, 14b) articulated on the arm (7), such that when the two jaws (14a, 14b) are tightened, after the arm (7) has been lowered onto the bearing surface to be machined, the three blocks (13, 16a, 16b) are arranged at the corners of an equilateral triangle and exert a uniform and controllable pressure on the workpiece (1). <IMAGE>
