摘要

Machining unit and machine tool for punching machining of workpieces, in particular sheetsA processing unit (6) of a machine tool (1) for the punching processing of workpieces, in particular of sheets (5), has a punching tool carrier (7) for a punching tool and a scraper carrier (9) for a scraper (10). The punching tool carrier (7) is movable by means of a punching drive (12) along a lifting axis (11) by a transverse drive element (17, 18) by means of a punch drive motor (14) relative to the punching tool carrier (7) with a drive transverse movement along a transverse movement axis ( 19) can be driven, which extends in the transverse direction of the lifting axis (11). The scraper carrier (9) is movable by means of a scraper drive (13) along the lifting axis (11), wherein the transverse drive element (17, 18) of the punch drive (12) during the transverse drive movement relative to the scraper carrier (9) along the transverse movement axis (19 ) is movable and the punching tool carrier (7) and the scraper carrier (9) relative to each other along the lifting axis (11) are movable. A machine tool (1) is provided with a processing unit (6) of the above type.
