Working machine for making gears

A machine (1) for making gears,

• the machine (1) comprising at least two piece-holder units (3*;
• 3**) and at least one operating unit (20) comprising a first slide (22);
• said at least one operating unit (20) being equipped with at least one operating head (30) provided with at least one tool (33;
• 33A, 33B) for machining a piece;
• said at least two piece-holder units (3*;
• 3**) and said at least one operating unit (20) each being structurally configured such that each of said at least two piece-holder units are capable of moving in at least a first direction (X1, X2) relative to a position of said at least one operating unit, with each piece-holder unit of said at least two piece-holder units also being moveable with respect to the other piece-holder unit in said first direction (X1, X2);
• wherein said at least one operating unit (20) is suitable to move in a second direction (Y1) substantially perpendicular to said at least first direction (X1, X2);
• wherein said at least one operating unit (20) includes a second slide (25) mounted on a pivoting element (24), said pivoting element (24) being moveable in a third, rotational direction (A) about an axis (W);
• wherein said at least one tool (33;
• 33A, 33B) is mounted on said second slide (25), said second slide (25) being configured to move in a fourth direction (Y) which is tangential relative to said axis (W);
• wherein said pivoting element (24) is mounted on a third slide (23), said third slide (23) being configured to move in a fifth direction (Z) transversal to said second direction (Y1);
• and
• wherein said at least two piece-holder units each comprise a piece-holder table which is rotationally driven to rotate about a respective vertical axis.

• and
• wherein said at least two piece-holder units each cooperate with a respective operation unit, each operation unit comprising a respective vertical column and including a respective support arm extending from the respective vertical column such that, for each of the support arms, a respective vertical axis intersects both the respective piece-holder unit and the respective support arm, wherein each support arm is configured to support a respective auxiliary device comprising:
• a device for machining a piece mounted on a respective one of said at least two piece-holder units, and/or for controlling a piece mounted on a respective one of said at least two piece-holder units.
