Abstract: A machine for making gears. The machine comprises a piece-holder unit and an operating unit equipped with an operating head provided with at least one tool for machining a piece. Moreover, one piece-holder unit and the operating unit are provided with relative motion with respect to each another in a direction. The machine is characterized in that the operating unit is suitable to move, in a direction substantially perpendicular to the direction, and in that the tool is mounted on a slide provided with a tangential motion defined by a direction.

Abstract: A machine for making gears. The machine comprising at least one piece-holder table, which is mounted to rotate about a given first longitudinal axis thereof, and supports a piece being machined; and at least an operating head, which is provided with at least one tool for machining the piece. The machine is characterized in that the piece-holder table and the operating head are provided with relative motion with respect to each other in a first direction. Moreover, the operating head and the piece-holder table can be selectively stopped along their respective path according to the machining process to be carried out on the piece.
