The present invention relates to an anterior spindle device for use on a machine tool, comprising a clamping interfacefor clamping the anterior spindle device on a work spindle of the machine tool, an anterior spindle unitwith a spindlefor driving a drilling tool clamped on the spindle, a drivefor exerting a force on the anterior spindle unit, and an electromagnetic actuatorfor exerting a counterbalancing force opposite to the force of the driveon the anterior spindle unit

Anterior spindle device for use on a machine tool

The present invention relates to a method and a device for controlling an ultrasound tool unit for machining a workpiece on a machine tool. For this, a plurality of parameter sets are stored on a storage device of a control device of the machine tool. When controlling an ultrasound transducer of the ultrasound tool unit received on a work spindle of the machine tool on the basis of a sensor signal input into a controller by means of a generator operated by the controller, on the basis of a first parameter set, which is associated with the ultrasound tool unit and sets the operation of the controller, an operating setting of the controller is switched by changing the first parameter set setting the operation of the controller on the basis of a second parameter set, which is associated with the ultrasound tool unit, of the plurality of parameter sets stored on the storage device.
