Abstract
(EN)
This dust-proof mechanism of a chuck is provided with: a fluid supply source; an internal space provided inside the chuck; and a discharge space provided to the chuck. The fluid supplied from the fluid supply source is supplied to the internal space, and pressurized and passes through the internal space. The discharge space discharges the pressurized fluid from the internal space to the outside of the chuck.
(FR)
Ce mécanisme anti-poussière d'un mandrin est pourvu : d'une source d'alimentation en fluide; d'un espace interne disposé à l'intérieur du mandrin; et d'un espace de décharge disposé sur le mandrin. Le fluide fourni par la source d'alimentation en fluide est fourni à l'espace interne, est pressurisé et passe à travers l'espace interne. L'espace de décharge évacue le fluide sous pression de l'espace interne vers l'extérieur du mandrin.
