Abstract
Die vorliegende Erfindung betrifft ein Maschinenteil, das in Schichten mit unterschiedlichen Waermeausdehnungskoeffizienten aufgebaut ist, um eine thermisch bedingte Verformung des Maschinenteils zu verhindern.
DE 19833741 C UPAB: 20000405 NOVELTY - The individual layers have different thermal expansion coefficients, each one depending on the temperature change in the layer relative to a temperature change in at least one other layer. The thermal expansion coefficient decreases towards the heat source and/or increases towards a heat sink. USE - For a CNC machines. ADVANTAGE - Manufacturing errors or tolerances are avoided or reduced, ensuring that heat emitted by e.g. motors, gears, bearings, guides or machining work does not lead to the bed being deformed and therefore unlevel.
