Abstract
A milling and drilling machine comprising a rigid machine tool frame comprising an upper cross girth, a machining unit movable on the front side of the cross girth along at least two coordinate axes by means of a motor and including a rotationally driven work spindle including exchangeable tools, and a workpiece table which is disposed in front of the machine tool frame and horizontally movable along at least one coordinate axis by means of a motor and comprises a tabletop for clamping at least one workpiece. The machine tool frame comprises two rigid side walls rigidly connected to each other by the upper crossbar and a front end.
Claims17
A milling and drilling machine comprising:
- a rigid machine tool frame comprising two generally parallel side walls having inner sides and front end portions, and an upper crossbar attached to said side walls;
- a machining unit movable on said upper crossbar along at least two coordinate axes and including a rotationally driven work spindle configured to engage exchangeable tools;
- a front end comprising the front of said machine tool frame and having horizontal guide rails mounted on said front end;
- a workpiece table arrangement comprising a table top for clamping a workpiece, said workpiece table arrangement being disposed on said horizontal guide rails so as to be movable in a Y coordinate axis;
- elongated supports on said front end are provided on which said guide rails for said workpiece table arrangement are mounted, said supports being adjacent to said inner sides of said side walls of said machine tool frame;
- and
- two electrically synchronised linear motors provide the drive for the shifting movements of said workpiece table arrangement along the Y coordinate axis, said motors having secondary and primary parts, the secondary parts of said motors being attached to said inner sides of said side walls of said machine tool frame, the primary parts of said motors being vertically mounted to said workpiece table arrangement.
A workpiece table arrangement for a milling and drilling machine comprising a rigid machine tool frame comprising two generally parallel side walls having inner sides and front end portions, and an upper crossbar attached to said side walls, a machining unit movable on said upper crossbar along at least two coordinate axes and including a rotationally driven work spindle configured to engage exchangeable tools, a front end comprising the front of said machine tool frame and having horizontal guide rails mounted on said front end, the workpiece table arrangement comprising:
- a bridge comprising a central bar and being pivotable about a horizontal axis;
- a plane table top coupled to said central bar and comprising clamping means for clamping workpieces thereto;
- bearing legs connected to each end of said central bar of said bridge, said bearing legs being supported in a respective slide so as to be synchronously rotatable;
- and
- said two slides respectively comprising a drive unit and guide shoes.
