摘要： The invention relates to a method for grinding the exterior of a shaft part (10) with rotationally symmetrical sections and bases which have centering bores and which define a reference longitudinal axis and rotational axis of the shaft part. In the method according to the invention, the shaft part (10) to be ground is held between tips (11, 14) which engage into the centering bores during the grinding process using a grinding disk (1), and the shaft part is additionally supported on the rotationally symmetrical sections by means of a support device (2, 2', 3, 35). Furthermore, the current diameter values of the rotationally symmetrical sections of the shaft part (10) are measured and transmitted to a controller, by means of which the support device (2, 2', 3, 35) is updated with respect to the measured diameter values while continuously supporting the rotationally symmetrical sections until the target dimensions of the shaft part (10) are achieved. The invention additionally relates to a system for carrying out the method, consisting of a grinding machine and such a shaft part (10). The grinding machine belonging to the system has a support device (2, 2', 3, 35) with a first and a second support unit, which can be moved relative to each other and dependent on each other. The measurement signals of the current diameter of the rotationally symmetrical section of the shaft part (10) are forwarded to a controller by means of the measuring device (21), and the first and the second support unit (2, 2', 3, 35) can be constantly updated with respect to the current diameter of the rotationally symmetrical section on the basis of the measurement signals such that the shaft part (10) is doubly supported by the support units (2, 2', 3, 35) opposite the grinding disk (1) and by tips (11, 14) which are in engagement with the shaft part.

摘要： The invention provides a grinding machine for the complete machining of workpieces, in particular gearwheels for transmissions, on both planar sides and within a central bore on one and the same machine, and a method which is carried out on the grinding machine. The grinding machine has a workpiece headstock and two grinding headstocks, wherein the first grinding headstock has two grinding spindles with in each case one grinding wheel for grinding the first and second planar and also the non-planar external surfaces, and the second grinding headstock has a grinding spindle having a grinding wheel for grinding the central bore in the workpiece. The second grinding headstock additionally has, in an equipment unit, a clamping device, in particular in the form of a mandrel, which clamps the workpiece in the bore once grinding of the bore has been completed. The grinding machine is thus configured such that first of all the bore and the first planar and any non-planar external surface that is present are ground on the one side of the workpiece, wherein the bore and the first external surface are ground at least temporally in parallel, this being followed by the clamping of the workpiece by way of the clamping device in the bore. Thereupon, the clamping by the workpiece headstock is released such that the now released second planar external surface can be ground in one and the same grinding machine with one of the grinding wheels of the first headstock. The clamping with the clamping device attached to the second grinding headstock thus takes place in that the central axis of the clamping device is aligned exactly with the central axis of the workpiece headstock, with the result that clamping in a precise position is achieved even in the case of changing clamping in the grinding machine.

摘要： In a workpiece grinding method, a grinding allowance of a predetermined width (T) at at least an end surface portion 21 of a workpiece W is removed with a grinding wheel 10 (or 32) by rotating the workpiece W having a cylindrical portion 20 and the end surface portion 21 perpendicular thereto, by rotating the grinding wheel 10 (or 32) supported rotatably about an axis extending in parallel with the axis of the workpiece 10 (or 32), and by moving the grinding wheel 10 (or 32) relatively to the workpiece W. The method comprises a first grinding step of grinding the end surface portion 21 to an approximately right triangle shape in section by infeeding the grinding wheel 10 (or 32) from a grinding start position (S), where the grinding wheel 10 (or 32) overlaps the circumferential surface of the end surface portion 21 through the predetermined width (T) or a narrower width, toward an infeed end position (E) on the side of the cylindrical portion 20 in an oblique XZ-direction; and a second grinding step of removing a grinding allowance of the approximate right triangle shape in section left without being ground at the first grinding step, by feeding the grinding wheel 10 (or 32) in an approximately axial direction of the workpiece W

摘要： A method for removing a predetermined amount of material from the inner surface (16, 18, 20, 22) of a circular article (10) which deviates from a true circular configuration. The outer surface (32) of the article (10) is touch probed to determine its true location in space, data are then compared to engineering design data to establish the location of the surface (16, 18, 20, 22) to which material removal is desired. A control computer (70) sends commands to the machine control system, causing the machine to remove the excess material down to the desired dimension. Any deviations from circular are compensated for by moving the article (10) radially relative to the cutting tool as the article (10) moves circumferentially relative to the cutting tool.
