Definitions
- the present invention relates to the field of accessories for machine tools, numerical control, machining centers, cells and flexible workshops and relates to a hydro-expandable milling chuck.
- the milling tools or milling cutters used on the aforementioned machines are generally in the form of substantially cylindrical elements mounted by means of a bore on a hub of a tool holder and clamped on the latter by means of a screw .
- the milling mandrel according to the invention consisting of a mounting body on a tool holder and provided with a hub for fixing a milling body, is characterized in that the fixing hub a strawberry body is hydro-expandable.
- FIG. a side elevational view and partially in section of a milling mandrel according to the invention provided with a milling cutter
- FIG. 2 is a front elevational view of the mandrel alone
- FIG. 3 is a sectional view along AA of FIG. 2.
- FIGS. 1 to 3 of the accompanying drawings represent, by way of example, a milling mandrel consisting of a mounting body 1 on a tool holder and provided with of a hub 2 for fixing a milling body 3.
- the hub 2 for fixing a mill body 3 is hydro-expandable.
- the hub 2 has an outer sleeve 4 provided with an annular chamber 4 'with a thin outer wall, this chamber being connected to a means 5 for pressurizing, passing through the body 1.
- the fluid under pressure is advantageously oil and the supply of this oil under pressure in the annular chamber 4 'of the sleeve 4 has the effect, under the effect of the high pressure of the oil injected into said chamber 4' to cause elastic deformation its outer wall which is thus pressed against the wall of the central bore of the cutter 3.
- the outer sleeve 4 is an insert attached to the hub 2 by shrinking, soldering or other and the means 5 is advantageously connected to the annular chamber 4 'by means of a bore disposed, in known manner, in the hub 2 and opening through the wall thereof in the annular chamber 4'.
- the hub 2 of the milling cutter body 1 is advantageously provided, in addition, with longitudinal bores 8 extending parallel to its axis.
- lubrication channels provided in the body of the cutter 3 to open near the cutting plates 3 'of the latter, these longitudinal channels 8 opening to their other end in a chamber 9 connected to an axial conduit 10 for supplying lubricating liquids.
- the chamber 9 may, for example, correspond to an obviously made in the body 1 close to the end of the screw 7 for clamping the cutter 3 when the latter is fully tightened. Thanks to the invention, it is possible to make a milling mandrel to obtain a perfect centering of the tool, so that its adjustment can also be performed perfectly and reproducibly without specific adaptation to each tool.
- the provision of lubrication channels at the periphery of the hub 2 makes it possible to ensure that the front portion of the tool is properly supplied with lubricating fluid.
