    摘要： A process finishes the surface of rotationally symmetrical workpieces. The workpiece is pre-machined and hardened with a stock allowance and is then finished in two steps in a device in which it is clamped only once. The largest part of the stock allowance is first cut by a hard turning process and the residue is then ground down to the actual size of the workpiece to be manufactured. The device for performing this process includes a motor-driven workpiece spindle for receiving the workpiece having a spindle head. The workpiece spindle has at least one motor-driven grinding spindle adapted to accept a grinding tool. The grinding spindle generally is axially aligned with the workpiece spindle or the workpiece thereon. The workpiece spindle can be fitted with a lathe tool having a cutting edge for hard turning.

    摘要： The cylindrical peripheral surface of a rotating workpiece is ground by a first section of a rotating grinding wheel while a second section of the grinding wheel is used to simultaneously grind a thread into the peripheral surface so that the reduction of the diameter of the peripheral surface and the forming of a thread therein take place in one and the same operation. The two sections can constitute integral parts of a one-piece grinding wheel or two discrete spaced-apart components of a composite grinding wheel. The diameters of the freshly ground portions of the peripheral surface are monitored by a measuring head which transmits appropriate signals to a computer for regulation of the controls of the grinding machine so as to change the position of the grinding wheel relative to the rotating workpiece if the diameter of the ground portion of the peripheral surface deviates from a preselected value. The same measuring head can be used to ascertain radial deviations of the rotating workpiece. The profile of the second section of the grinding wheel remains unchanged in the course of the grinding operation. This is achieved by using a highly wear-resistant second section and/or by continuously dressing the second section during removal of material from the workpiece.

    摘要： A machine tool includes a main shaft unit; a polishing head for processing a workpiece; and an unnecessary byproduct leakage preventing unit for preventing leakage of abrasive resulting from processing at or around a part of the workpiece, the part being processed, and wherein the unnecessary byproduct leakage preventing unit includes a cover provided separately from the polishing head, the cover having a structure that is open in three directions and that has walls in another three directions such that a protection space where to hold a part of the workpiece is defined, the cover for receiving the abrasive, and a movement mechanism for moving the cover so as to stay apart from the workpiece while the workpiece is not being processed and so as to have a part of the workpiece held in the protection space while the workpiece is being processed.

    摘要： On a workpiece there are first longitudinal portions which are rotationally symmetrical with respect to the continuous longitudinal axis and are intended to be ground by way of centerless grinding. The workpiece also has a second longitudinal portion, which is not rotationally symmetrical with respect to the longitudinal axis and would lead to imbalance in the event of rotation. Therefore, a balancing weight having a radially extending recess is placed on the second longitudinal portion. The balancing weight contributes largely to uniform distribution of the rotating masses, thus reduces the imbalance to a very low residual imbalance and allows reliable and precise centerless grinding.
