Abstract: Workpiece headstock for a machine tool, especially for a grinding machine, with a spindle (6); with a clamping device (7), which is connected to the spindle (6) and which is used to clamp a workpiece (8) to be machined; and with a spindle drive (9), where, a loosenable alignment interface (14) is provided between two sections of the spindle (6), between the spindle (6) and the clamping device (7), or between two sections of the clamping device (7); where, after the alignment interface (14) has been loosened and while the workpiece headstock (1) otherwise remains stationary, the clamping device (7) and thus the workpiece (8) clamped in it can be aligned in a plane perpendicular to the spindle axis (15), as a result of which any existing offset between the workpiece axis (17) and the spindle axis (15)—i.e.

Abstract: The grinding machine (10) according to the invention serves in particular for the machining or production of tools. It comprises a machine bed 11 and a workpiece spindle (14) arranged thereon, which receives the workpiece (13) to be machined, as well as a grinding station (19) arranged next to the workpiece, the station having a grinding spindle for the reception of a grinding tool (20), and is provided with a workpiece guide system (23) arranged at the machine bed for the support of the workpiece at the grinding location (21).
