The invention relates to a milling device with universal gear and automatic indexation, removably mounted on a milling head bearing a machining spindle, comprising a main body mounted on the milling head and capable of occupying several positions of indexation with respect to said head by rotation about an axis XX1 lying in line with the axis of the spindle of the milling head, said main body laterally bearing a spindle-holder unit capable of occupying several positions of indexation with respect to the main body by rotation about an axis YY1 perpendicular to axis XX1, the spindle of the unit itself being perpendicular to axis YY1, wherein the spindle of the milling head is connected to the spindle of the spindle-holder unit by a kinematic chain comprising a shaft or sleeve disposed along axis YY1 and on which is mounted a gear which is in mesh with a ring gear fast with the spindle-holder unit during the operation of indexation and which is not of mesh with said ring during the work operation. |
