High performance milling spindles with high rigidity and high speed are required for high productive machining. A preload switching spindle has been designed to obtain high rigidity at low speeds while avoiding bearing burn at high speeds. In this report, the load-displacement relationship of a preload switching spindle is measured with a non-contact magnetic loading device. Measurement and simulation results are compared to clarify the rigidity change by preload switching.
