Abstract
The present invention concerns a sealing system for a tool holder of a fluid-assisted axial machining or milling machine, including:—at least first and second seals contributing to define a space for the flow of fluid to at least one inner channel of the tool, one of the seals being applied to the tool or an optional adapter carrying the tool and the other seal a) being applied to the tool or to the adapter carrying the tool or b) being applied to a surface spaced apart from the tool and rotating with same, with 0.3≦Do/Djmax for Do in the interval [1; 3] in mm and 0.5≦Do/Djmax for Do in the interval [3; 20] in mm, where Do is the diameter of the tool facing this other seal and Djmax is the internal diameter of this seal.
Claims13
A sealing system for a tool holder of a fluid-assisted milling or axial machining machine tool, comprising:
- at least a first and a second seal contributing to delimiting a space for the circulation of the fluid toward at least one internal passage of the tool, one of the seals pressing against the tool or a tool-bearing adapter there may be, and the other seal pressing against a surface spaced away from the tool and rotating with the latter,
- with 0.3≦Do/Djmax for Do in the range of 1 mm to 3 mm and 0.5≦Do/Djmax for Do in the range of 3 mm to 20 mm, where Do is the diameter of the tool facing this other seal and Djmax is the internal diameter of this seal.
