영문 초록

In today s machining environment, heavy cutting at a low speed and light cutting at a high speed, as are often performed on a single machine tool, must be carried out successively for highly efficient machining as well as high speed machining. Therefore, current machine tool spindles require great stiffness and high speed rotation performance simultaneously. To that end, a preload device is needed so that the bearing that can apply a greater preload to raise the stiffuess of the spindle at the low-speed range while a smaller preload at the high-speed range to reduce heat generation as opposed to greater stiffness and to allow high-speed rotation. In this study, the new concept of an automatic variable preload device that can adjust the preload applied to spindle bearing using electromagnetic was proposed. A prototype for the automatic variable preload device using electromagnetic was created. With the prototype, it was confirmed that the preload device based on the proposed structure worked properly.
