Thermal Characteristics of the Headstock System on the NC Precision Lathe

摘要

High speed and high quality precision are essential requirements of NC lathes in modern industry. Since the heat generated from headstock system is a major factor causing machining inaccuracy, in this work, the thermal 3D model of the headstock system is built and its thermal characteristics are investigated using FEM. From the comparison of the numerical results with the experiment results, it is found that the FEM predicted well the thermal characteristics of the headstock system and the model is reliable to further optimum design of the headstock system.
