Thermal Characteristic Analysis CNC Multi-Grinding Machine

Abstract:

Recently, it is essential to enhance the value of the products to make them more competitive. Therefore, the technical level of the high-precision products is required. Thermal deformation error, which accounts for a significant effect of processing accuracy of machine tools. In order to reduce thermal deformation error such studies the thermal characteristics of the Hydrostatic spindle is required. In this study, we could confirm the reliability of the analysis by assessing the thermal characteristics through measurement of the grinding machine temperature and thermal structural analysis. The temperature of the front bearing 10 °C or more higher than the temperature of the rear bearing, thermal deformation of the spindle, was found to be dependent on the temperature of the hydrostatic bearing. And could identify the thermal characteristics of the hydrostatic spindle.
