Abstract
The aim of the invention is to provide a robust, simple woodworking machine. To achieve this, the invention provides a machine comprising at least one linear direct drive, which contains a primary part () with a first element () for generating a first magnetic field and at least one additional element () for generating an additional magnetic field. The first element () for generating the first magnetic field is positioned, in particular, in such a way in relation to the additional element () for generating the additional magnetic field that the first magnetic field overlaps the additional magnetic field. The machine also comprises a secondary part (), which comprises magnetic return elements and is devoid of magnetic sources. According to the invention, the primary part () and/or the secondary part () is or are suitable for guiding or placing at least one workpiece and/or for guiding and/or placing at least one tool for machining the workpiece.
