<p>A machining unit, particularly for machining the surface of cylindrical cavities, has a tool-holder assembly (11), including an electric actuator (15) for adjustment of the radial tool position (21). The control signals of the actuator (15) are transmitted to said actuator by a stationary electronic control unit (28) via a wireless communication system (29, 30). Also provided on board the tool-holder assembly (11) is a system for electrical supply of the actuator (15), constituted, for example, by one or more batteries (31) or else by an electrical-generation microsystem (32) that exploits a portion of the flow of the high-pressure lubricant-coolant that is fed into the machining area.</p> |
