摘要： A work spindle for a machine tool. The work spindle has a spindle guard tube, a clamping arrangement, a clamping force generator, which is arranged on the spindle guard tube and operates the clamping arrangement, and which has at least one first cylinder chamber enclosed by a first cylinder housing and a first piston, in such a way that a large band width of different clamping forces may be generated simply. The clamping force generator has a second cylinder chamber enclosed by a second cylinder housing and a second piston. Additionally, for operation of the clamping arrangement, both cylinder chambers are always subjected to a pressurized medium. Furthermore, to generate different clamping forces, the clamping force generator is switchable over from a first working mode, in which at least the first piston operates the clamping arrangement, into a second working mode, in which at least the second piston operates the clamping arrangement.
