Device for grinding and/or milling teeth of saw bands

1 . A device for grinding and/or milling teeth of saw bands, comprising:

a feed device for the clocked feeding of a temporary workpiece, wherein the temporary workpiece is formed from a plurality of mutually parallel saw bands, wherein the feed device comprises a feed slide and a feed drive,

a clamping unit arranged on the feed slide, the temporary workpiece being clamped into the clamping unit, such that the clamping unit and the temporary workpiece are displaced along a feed direction by the feed drive, and

a machining unit with at least one machining tool for simultaneous machining of a plurality of teeth of the temporary workpiece, wherein the clamping unit is displaceable together with the feed device along the feed direction,

wherein the clamping jaw edges of the clamping unit are oriented along the feed direction and are at least twice as long as a machining width of the machining tool, and

wherein the clamping jaw edges have a tooth contour at least in sections with a plurality of teeth.

2 . The device according to claim 1 , wherein the clamping unit is arranged on the feed device.

3 . The device according to claim 1 , comprising a press down unit for pressing down the temporary workpiece that is arranged on the feed device.

4 . The device according to claim 1 , comprising a first auxiliary clamping unit arranged in front of the clamping unit along the feed direction and a second auxiliary clamping unit arranged behind the clamping unit along the feed direction.

5 . The device according to claim 1 , wherein the machining unit has a grinding tool and/or a milling tool.

6 . The device according to claim 1 , wherein the dressing unit is displaceable along a first and/or a second axis for dressing the machining tool, wherein the dressing unit has a respective dressing drive for the displacement along the first and second axis.

7 . The device according to claim 6 , wherein the dressing unit has a receptacle for receiving at least two dressing tools which are different from one another.

8 . The device according to claim 6 , wherein the machining unit has a sensor unit, wherein a contact between the machining tool and the dressing tool is measurable by the sensor unit.

9 . The device according to claim 1 , comprising a cooling unit for cooling the machining tool that comprises a plurality of nozzles directed at the machining tool.

10 . A method for grinding and/or milling teeth of saw bands, comprising the following steps:

pressing down and clamping a plurality of parallel, identical saw bands to generate a temporary workpiece,

first simultaneous machining of a first plurality of teeth of the temporary workpiece to generate either tooth backs and/or tooth faces,

first displacement of the temporary workpiece along a feed direction,

second simultaneous machining of the first plurality of teeth to generate either tooth backs and/or tooth faces, depending on which were not generated during the first simultaneous machining,

second displacement of the temporary workpiece along a feed direction, and

direct repetition of the first displacement of the temporary workpiece and of the first and second simultaneous machining of a further plurality of teeth of the temporary workpiece.

11 . The method according to claim 10 , wherein the temporary workpiece is moved farther by the second displacement than by the first displacement.

12 . The method according to claim 10 , wherein the first and/or second displacement of the temporary workpiece is less than or equal to a machining width of a machining tool.

13 . The method according to claim 10 , wherein a clamping unit, clamping the temporary workpiece, and a feed unit, displacing the temporary workpiece, are moved together in an unchanging relative position to one another.
