摘要

The machine (100) has a pin (3) attached to a frame (2) to hold and/or pivot a piece around an axis (6) of pin. Machining tools (4) machine the piece, and a recovery device (8) covers chips and/or oil. A cowl (1) has an opening and a protective cover (5) to pivot around a horizontal rotation axis (7) between an open position to allow access to the pin and the tools and a closed position to protect an operator. The cover is provided below a horizontal plane containing the axis of the pin in the open position and above the plane in the closed position. The protective cover is made of metallic, plastic or composite material.
