摘要： A dynamic spindle adjustment permitting an adjustment movement for the compensation of a wobble of the body held by the work spindle is provided on the spindle bearing of a machine tool. The regulation is designed at least dynamically enough for the regulation to permit a reliable tracking of the rotating work spindle. As a result of this, one or more spindles can be moved relative to a stationary machine in such a manner that the path of a body held on the work spindle represents an ideal rotation about the desired body axis, that is, the axis of symmetry. The compensation motion can be achieved by energizing appropriate actuators of the bearing devices with sinusoidal and cosinusoidal adjustment signals, which are superimposed to produce a circular motion of the affected bearing device. This circular motion compensates for orbital motions of the misaligned body (7) held on the work spindle.

摘要： A method for calibration of grinding and/or erosion machines assumes an initial calibration process and corresponding re-calibration processes. Calibration of the machine is performed with a reference piece and a reference tracer in an initial calibration process whereby the reference piece is fastened to a working spindle or a workpiece carrier and the reference tracer is fastened to the workpiece carrier or the working spindle. Grinding tests follow the first tracing process from all directions during which tests deviations are determined and made ineffective with the iterative procedure, especially deviations based on the tolerance of the tracer, which are an integral part of the tracing process. The machine-internal measuring system is calibrated immediately after performing the machining tests and thereby immediately after the initial referencing of the machining apparatus whereby the machine tracer and a test piece is traced from all coordinate directions and the resulting position values are stored. Subsequent re-calibrations supply measured values, which are compared to the stored values whereby correction values are determined then from the deviations for additional machining of workpieces.
摘要翻译：研磨和/或侵蚀机器的校准方法采用初始校准过程和相应的重新校准过程。在初始校准过程中使用参考件和参考示踪器进行机器的校准，由此将参考件紧固到工作主轴或工件载体上，并且将参考示踪器紧固到工件托架或工作主轴上。磨削测试遵循从所有方向进行的第一个跟踪过程，在此过程中测试偏差被确定，并且与迭代过程无关，特别是基于示踪器的公差的偏差，这是跟踪过程的组成部分。机械内部测量系统在执行加工测试之后立即校准，并且在加工设备的初始参考之后立即被校准，从而从所有坐标方向跟踪机器示踪器和测试件，并且存储所得到的位置值。随后的重新校准提供测量值，其与存储的值进行比较，从而从工件的附加加工的偏差确定校正值。
