Abstract
A modular contact assembly for transferring electrical energy from a fixed object to a rotating object, and a machine tool that includes the contact assembly. The machine tool may include a housing, a rotating spindle mounted in the housing, and an electrical device mounted in the rotating spindle. The contact assembly includes a mounting plate joinable to a housing by movement of the plate into an attached position on the housing; a first brush assembly, first and second electrical contacts disposed in the mounting plate, an actuator joined to the mounting plate, and a first energy supply connection disposed in the mounting plate and in communication with the actuator. The machine tool may also include a magnet that is rotatable a quarter turn to retain the contact assembly in the machine tool. The electrical device may be an ultrasonic transducer operable to perform ultrasonic machining by the tool.
