Head for the continuous precision machining on three-dimensional bodies and machining equipment that comprises said head

A head for the continuous precision machining on three-dimensional bodies, comprising:

• a fastening means to a flange of a machining equipment, with a first mechanical rotating axis, an intermediate means with a second mechanical rotating axis in series with said first mechanical rotating axis, said second mechanical rotating axis being orthogonal with reference to said first mechanical rotating axis, with which it intersects at an intersection point, and a terminal machining means having in series with said first and second mechanical rotating axes a third mechanical translation axis, said intermediate means having a shape of an arc of a circumference the centre of which is located at said intersection point, and said first mechanical rotating axis and said third mechanical translation axis being oriented radially to said arc, wherein said intermediate means comprises a first support and guide part, a second support and guide part guided by said first part for rotating around said second axis, a third part guided by said second part for rotating around said second axis (B) independently of the rotation of said second part around said second axis.
