Abstract: A manufacturing machine for manufacturing a cylindrical battery having a cylindrical case which houses an electrochemical cell. They are provided: a processing conveyor configured to move forward along a processing path a seat designed to support the cylindrical case; and an operating group which is arranged along the processing path and is configured to perform a processing on the cylindrical case. The operating group has: a support body axially aligned with the corresponding seat and mounted to rotate around a rotation axis; and a plurality of processing discs, which are configured to perform a machining on the side wall of the cylindrical case, are uniformly mounted on the support body to form a circle at the centre of which the cylindrical case is placed in use, and are radially movable to radially get close to and move away from the cylindrical case which is in use between them.
