PRECISION GUIDING DEVICE IN A MACHINE FOR MACHINING CYLINDRICAL PARTS

摘要

The part to be machined (2) is attached so that its axis lies in a position exactly determined relative to the base of the machine (1) and to the pedestal (3) due to the flanges (8) and the rear face (9) of the V formed on the pedestal, and due to an intermediate member (11) having the shape of a crown sector in which the concave cylindrical faces (23) are adapted to the part (2). The part is pressed against the faces (23) by a lug (14) actuated by the calliper (15). The part (2) can be rotated by a floating pin actuated by a servomotor in a determined position relative to the base of the machine (1).
