Abstract:
1. A drilling method using a drilling device comprising a rotating tool and a drilling machine capable of turning the tool in rotation, and lubrication means capable of lubricating the rotating tool, said drilling device further comprising: an intermediate chamber for storage of chips produced during an elementary drilling operation; introduction means, for introducing said chips into the intermediate storage chamber during the elementary drilling operation, said introduction means being designed so as to operate other than by generating an airflow; a main chamber for storage of chips communicating with the intermediate storage chamber; and scavenging means capable of generating an airflow scavenging said chips, the drilling method comprising said elementary drilling operation performed using the rotating tool and the drilling machine, and a lubrication operation of the rotating tool performed using the lubrication means, said lubrication operation being performed during the elementary drilling operation, wherein said elementary drilling operation is performed using said introduction means, without activating said scavenging means, and said elementary drilling operation is followed by an airflow scavenging operation of the chips stored in said intermediate storage chamber via said introduction means during said elementary drilling operation, said scavenging operation being performed with said scavenging means such that the chips are scavenged from said intermediate storage chamber towards said main storage chamber.
