摘要
A grinding machine for machining workpieces includes a workpiece headstock and two grinding headstocks. A first grinding headstock has two grinding spindles each with one grinding wheel for grinding first and second planar and non-planar external surfaces. A second grinding headstock has a grinding spindle having a grinding wheel for grinding a central bore in the workpiece, and a clamping device to clamp the workpiece. First, the bore and the first planar and any non-planar external surface are ground on one side of the workpiece. Then, the workpiece is clamped in the bore. The second planar external surface can then be ground in the same grinding machine with one of the grinding wheels of the first headstock. The clamping device attached to the second grinding headstock is such that the central axis of the clamping device is exactly aligned with the central axis of the workpiece headstock.
