Abstract: Grinding a surface of a workpieces is accomplished with a grinding machine having at least two grinding units. First, a target structure of the surface to be achieved is provided. Then, using predetermined grinding parameters, a first of the two grinding units is used to grind the surface of the structure. Then, the surface of the actual structure is captured and compared to the target structure. Based on the comparison, the grinding parameters are adjusted and the surface is then ground, using the adjusted parameters, with the second of the two grinding units.

Abstract: A grinding device is operated by grinding of a surface of the workpiece with at least one grinding medium while recording actual data of the surface after grinding with at least one data collection device. Actual data recorded during grinding is then compared with target data stored in an electronic memory in an electronic data processing device. Based on the comparison, adjustments are made to at least one grinding parameter if a deviation of the actual data from the target data exceeds a predetermined limit.

Abstract: A grinding machine for grinding a surface of an object is described which has a plurality of grinding brushes which are rotatably mounted about a brush axis of rotation, at least one brush carrier on which at least one of the grinding brushes is mounted and which is rotatably mounted about a carrier axis of rotation, and a conveying device for conveying the object at a feed speed through the grinding machine. The grinding machine has an input device and an output device. A brush rotational speed about the brush axis of rotation and/or a carrier rotational speed about the carrier axis of rotation and/or the feed speed is/are adjustable by the input device, and an expected grinding result can be output by the output device.

Abstract: A grinding or sanding machine for grinding or sanding a surface of a workpiece includes a transportation device for transporting a work piece, a revolving grinding or sanding belt, and at least one pressure beam for exerting a pressure toward the transportation device. A plate is provided that is movable in a plane perpendicular to the direction in which pressure is exerted. The plate is disposed between the belt and the pressure beam. A drive device randomly moves the plate in plate movement directions in terms of either or both direction and speed.

Abstract: A profile grinding machine has at least two tool holders which are fixed in a frame and on each of which is fixed a grinding tool, for machining workpieces transported past the profile grinding machine in a working plane. The tool holders can be arranged in various angular positions, and their tools complement each other to give the desired profile shape. The advantages of a uniform grinding operation can be achieved in spite of the use of a plurality of tools by arranging the tool holders at essentially the same height in the transporting direction and by the tools of two neighboring tool holders forming the desired profile shape by a complementarily toothed design of the mutually facing edges, one engaging in the other.

Abstract: A belt grinding machine is disclosed that includes a pressure bar which has a plurality of pressure shoes arranged next to one another transversely relative to the conveying direction of the workpiece to be machined, and in which each pressure shoe has assigned to it its own pressing-on device actuable as a function of workpiece parameters, the pressing on force of the pressing-on device being controlled by means of a signal-processing unit taking into account the workpiece parameters and local and time data of the workpiece transport operation. A simple and comprehensive detection of workpiece parameters is carried out with the use of a light source which illuminates the surface of the workpiece linearly transversely relative to the conveying direction.

Abstract: A belt grinder with a pressure beam comprising a plurality of pressure pads arranged adjacent to each other, aligned transversely to the direction of transport of a workpiece and with a variable contact pressure, with grinding belts being guided over the surface of the workpiece to process it, with provision for varying individually and continuously the contact of each pressure pad so that uniform surface working may be obtained.
