Claims13
A spindle arrangement for a machine tool, the spindle arrangement comprising
- a rotor configured to rotate a tool holder, the tool holder being configured to hold a tool,
- at least one actuator configured to excite vibration of the tool, wherein the at least one actuator drives a compensation mass,
- a compensation device configured to at least partly compensate inertia forces produced by the vibration excitation in the rotor,
- a least one further actuator, and
- a further annular compensation mass configured to compensate radial vibrations that encompasses the rotor and is driven by the at least one further actuator that is diametrically arranged to the rotor axis.
