Abstract
A tool carriage for a machine tool is mounted on a support for movement between a working position and a rest position. The machine drive moves the carriage in a path from the rest position into the working position and thereafter permits return to the rest position. A spring interposed between the carriage and the support is stressed during carriage movement into the working position so that the stressed spring biases the carriage to return to the rest position. An auxiliary return device supplements the biasing force of the spring and thereby augments the force available for returning the carriage toward the rest position at least in a position of the carriage adjacent the working position.
