The invention relates to a device for machining processing, preferably of metal work pieces, comprising a tool (9) that rotates about a tool axis (W). In this way, with a tool of this type and the method for machining processing, the processing of large workpieces is possible in an efficient manner, despite each having at least individually and very precisely executed contours, and the device has a linear drive assembly (3) having at least one first linear drive (6), with which a tool holder (8) for rotatably holding the tool (9) is arranged on the tool carrier (1) such that it can move relative to the tool carrier (1).
