Modular clamping device

A clamping device for holding a workpiece during machining in a grinding machine, wherein the clamping device comprises:

• a support unit adapted to be mounted on the grinding machine,
• a clamping unit comprising a clamping anvil supported in a clamping anvil holding element and translationally drivable to apply a clamping force parallel to a clamping axis,
• a drive unit comprising a drive anvil supported in a drive axis and rotationally drivable for rotary orientating the workpiece by the drive axis,
• a measuring lever, and
• a measuring head which is in contact with the measuring lever and is configured to be actuated by the measuring lever, the measuring head configured to measure geometries of the workpiece to be held in a clamped position by the clamping device,
• wherein the clamping unit and the drive unit are provided as individual components, which are releasably or slidably attached to the support unit to form a workpiece spindle headstock of the grinding machine,
• wherein the measuring lever is arranged in the clamping unit and is provided to actuate the measuring head arranged in the support unit.
