Abstract (en)

[origin: EP0432078A2] The machine coordinates the movement of a carriage (5) supporting a shaft (33) for the rotation of grind wheels (34) and a movement perpendicularly to the former movement of a carriage (4) supporting a shaft (12) on which a lense (8) may rotate. The wheel holder shaft (5) is provided with a driving member (30) fixedly attached to a rotating cam (43) of variable width and a driven member (31) having a cam guide (44) which locks with the wider portion of the cam (43), there being only in this case a position of absolute locking between the driving member (30) and the driven member (31); an encoder (85) detects the successive popsitions and movements of the driven member (31) and a feeler (38) is adapted to detect positions of the lens (8) relative to the grind wheels (34).
