Universal milling machine

DETAILED DESCRIPTION What is claimed is: 1.
A universal milling machine comprising: a fixed frame, a supporting bracket; means mounting said supporting bracket in a central portion of said frame for pivotal movement about an axis, fixed with respect to said frame; a workpiece-holder table; means mounting said workpiece-holder table on said bracket for longitudinal translation in a direction fixed with respect to said bracket and parallel to said axis; a tool-holder casing; and means mounting said tool-holder casing in an upper portion of said frame; wherein said axis of pivotal movement of said bracket is above said table.
2.
A milling machine as claimed in claim 1, wherein said axis of pivotal movement of said bracket is located substantially in the longitudinal plane of symmetry of said table.
3.
A milling machine as claim in claim 1 wherein said axis is horizontal and said table is pivotable through 180.
degree.
between two vertical positions.
4.
A milling machine as claimed in claim 1 wherein said table includes a plate which is rotatable about an axis which is fixed with respect to the table and is perpendicular to and intersects said axis of pivotal movement of said bracket.
5.
A milling machine as claimed in claim 1 wherein the axis of said tool-holder casig is perpendicular to said axis of pivotal movement of said bracket and said casing is movable in a plane perpendicular to said axis of pivotal movement of said table.
6.
A milling machine as claimed in claim 1 wherein said axis of pivotal movement of said table is that of a circular window defined by said frame, a hollow cylinder to which said bracket is fixed being seated in said window and rotatable about said axis of said window.
7.
A milling machine as claimed in claim 6 including a motor fixed on said frame, a crown mounted freely on said hollow cylinder, means coupling said motor to said crown and means coupling said crown to actuate said table in its motions of translation and pivoting.
8.
A milling machine as claimed in claim 7, including a carriage, means mounting said carriage on said frame, means mounting said casing on said carriage and means coupling said crown to move said carriage on said frame and said casing on said carriage
