ABSTRACT:
In a grinding machine with a grinding means for machining a workpiece surface which can be moved in a direction of conveyance relative to the grinding means and is arranged in a machining plane, wherein the grinding means has a large number of grinding heads with grinding elements (8) rotating about a respective shaft, and the grinding heads can be moved by means of an endlessly revolving transporting means (1) in a grinding region (3) by deflection about deflection rollers via rectilinear portions in a grinding region at an angle to the direction of conveyance, improved grinding results are facilitated as a result of increased degrees of freedom in the setting of the grinding parameters without high costs for drive motors if a drive means (13), with which the grinding elements (8) are driven in rotation by a common motor provided for rotationally driving these grinding elements (8), is provided for at least one group of a plurality of grinding elements (8), and in that the drive means (13) consists of a flexible frictional engagement or positive engagement assembly which is guided parallel to the transporting means (1) about deflection rollers (22) and is formed with the shafts (17) of the grinding elements (8) for rotationally driving irrespective of the speed of transportation of the grinding elements (8).
