Peeling machine for elongated products

A peeling machine, comprising:

• a rotating head rotating about an axis of rotation and provided with a central cavity in which, during use, there is disposed an elongated product to be worked, said rotating head being provided with a plurality of tools and with at least one adjustment unit configured to move said tools away from or toward the elongated product;
• a first motor configured to make said rotating head rotate about said axis of rotation;
• and
• a transmission unit configured to transmit motion from a second motor to said adjustment unit in order to simultaneously adjust the radial position of said tools, said transmission unit comprising a differential device kinematically connected between said second motor and said adjustment unit so that an adjustment of the position of said tools with respect to said elongated product corresponds to the drive of said second motor,
• wherein said rotating head comprises a mandrel rotating about said axis of rotation by means of the drive of said first motor and a fixed structure in which said mandrel is housed,
• wherein said first motor is an electric motor comprising at least one rotor fixed to the mandrel and at least one stator mounted on said fixed structure and positioned around said rotor,
• wherein the machine further comprises a joint for distributing a cooling fluid housed in said mandrel and positioned in proximity of one end of the mandrel opposite an end of the mandrel connected to the rotating head and wherein a cooling system is able to send the cooling fluid to said joint and then, through a path made in the rotating head, to said tools,
• wherein said mandrel comprises a hole directed along said axis of rotation and in which there is housed at least one guide integral with said fixed structure.
