Thermal Model of High Speed Motorized Spindle

Market conditions imposed the need to significantly shorten the time cycle of the product development phase, with increasingly caused demands for the lowest possible price and highest possible quality. One of the main components of a machine tool that affects the accuracy and productivity of processing is the main spindle, that is, the motorized spindle. The integrated motorized spindle assembly is already widely used as the main spindle of machine tools. Among machine tool manufacturers, especially with precision machine tools, there is a tendency to predict thermal errors through numerical simulations. Correctly predicted errors are the basis for their efficient and easy compensation. The integrated FEM model enables effective improvement of the thermal performance of the entire machine tool, i.e. minimizing thermal errors and accurately predicting thermal errors for the purpose of error compensation.
