Machine tool with improved thermal stability and method for improving thermal stability in a machine tool||Machine tool with improved thermal stability and method for improving thermal stability in a machine tool

A machine tool with improved thermal stabilityincludes a workpiece support for supporting at least one workpiece for allowing machining of the workpiece, anda support structure including a tool carrier support. The tool carrier support supports a tool carrier configured for carrying and driving a tool for machining a workpiece supported by the workpiece support through a relative movement between the workpiece and the tool. The machine has a conduit configured to allow the flow of air in a closed circuit, the conduit has a surface part and an underground part, the surface part being an inner cavity of the support structure and the underground part having a piping configured to be buried in the soil beneath the support structure.
