ABSTRACT:
A non-contact rotation waterproof and dustproof method and a machine tool using the same. A viscous fluid is continuously or intermittently supplied to a labyrinth clearance formed between a rotating body and a fixed body from a fluid supply device so as to fill the viscous fluid into the labyrinth clearance to obtain a good non-contact rotation waterproof and dustproof method even when the rotating body is rotated at a low speed or is stopped.
