Abstract
A machine tool or a production machine, such as e.g. a multispindle machine, or a robot, is described, wherein a liquid metal lubricated slide bearing is not only used to transmit feed currents for electrical consumers but also to transmit currents for producing control signals. Accordingly, it is possible to apply via the liquid metal lubricated slide bearings a voltage of 600 volts in order to produce feed currents and a voltage of 24 volts in order to produce control signals.
