Claims

1. The method of machining pre-machined gear billets on a finishing machine, consisting of a base surface on which the first working body of the machine is movably mounted, a tool spindle for fixing the finishing tool is mounted on the first working body, a supporting element that is movable is mounted on the base surface, at least two positions, at least two spindles of products driven by one engine a gear, and at least one contact sensor for reconciling the position of the workpiece, while the alignment operation, which aims to ensure collision-free entry of the tool into the gaps between the surfaces of the teeth of the gear workpiece, is carried out on an untreated workpiece again placed on one of the product spindles before the moment the carrier moves to a position where such a raw workpiece will mesh with the tool.

2. The method according to claim 1, in which during the movement of the carrier element to the product spindles rotating relative to the rotating tool spindle, additional rotation is synchronized with the movement of the carrier element, resulting in a rolling movement that feeds the workpiece into the finishing tool area or leads it out out of it without a clash of working bodies.

3. A machine for processing pre-machined gear billets, including a base surface, a tool spindle for fixing a finishing tool, able to rotate around the first axis and driven by the first engine, a bearing element, moved by the second engine in at least two positions, at least two product spindles for fixing the workpiece, driven by one third engine, located on the supporting element at a certain distance from each other, rotating around the two second axes and connected to a rotary sensor, the at least one contact sensor for measuring the profiles of teeth of legs of one of the blanks in the moment of the carrier element in a position that would prevent the occurrence of such a blank into engagement with the finishing tool.

4. The machine according to claim 3, in which each product spindle is equipped with a separate sensor for calibrating the position of the workpiece, and the sensors are mounted on a supporting element.

5. The machine according to claim 3, in which the supporting element is able to rotate around the third axis, and the second axis and the third axis are parallel to each other.

6. The machine according to claim 3, further comprising a device for automatically replacing the processed workpiece with an untreated workpiece on one of the product spindles in a position that excludes the workpiece from engaging with the tool.

7. The machine according to claim 3, in which the tool dressing device is additionally installed on the carrier element, and the carrier element is able to move at least three positions, while the tool can be edited in one of three such positions.

8. The machine according to claim 3, in which the product spindles are rotatably mounted on one first movable working body that can move along the supporting element parallel to the corresponding second axis, while the first movable working body includes a supporting element that engages with the second a movable working body that can move along the base surface, at the moment the first movable working body is in the working position.
