Abstract

Selon des modes de réalisation, la présente invention concerne un dispositif intelligent de distribution d'agent de refroidissement sous la forme d'un bloc intelligent, le bloc intelligent comportant un ou plusieurs canaux internes de transfert d'agent de refroidissement intégrés en son sein. Du fait que l'agent de refroidissement s'écoule à travers les canaux internes du bloc intelligent en vue d'atteindre la zone de travail, la présente invention évite le montage de tuyaux de connexion externe quelconques pour distribuer ultérieurement l'agent de refroidissement à la zone de travail. Par conséquent, la présente invention empêche également une obstruction par copeaux et tout endommagement provoqué par les dispositifs de distribution d'agent de refroidissement dû aux copeaux. De plus, le bloc intelligent empêche une fuite de l'agent de refroidissement. Ce dernier permet également l'utilisation d'un agent de refroidissement à pression élevée comportant de nombreux effets bénéfiques, notamment une augmentation de la durée de vie de l'outil et une augmentation des paramètres d'usinage.
