Abstract: The invention concerns a grinding machine having displaceable grinding means for the processing of workpieces made from wood, wood composite materials, plastics, metals and similar materials. The invention further concerns a method of grinding a workpiece by means of the inventive grinding machine. The grinding aggregate comprises: at least one translational driving means configured to translate the grinding means (6) and at least one eccentric tappet configured to rotatingly move the grinding means (6). The inventive device is characterized in that the grinding aggregate comprises a suctioning device which suctions waste products of the processing, such as chips, through the grinding means. In this way, it is possible to achieve a qualitatively superior grinding result.

Abstract: The invention concerns a processing machine for the processing of workpieces preferably at least partially made of wood, wooden materials, plastics, metal or the like, comprising at least one load-bearing machine part and at least one processing unit connected to the load-bearing machine part, wherein the load-bearing machine part is made at least in sections from concrete. The inventive processing machine is characterized in that the concrete of the load-bearing machine part is formed by a concrete having a water-binder ratio of at most 0.30 and/or a bending tensile strength of at least 15 MPa.
