NC machines with improved worktable

Abstract

A numerical control machine includes a bearing structure-frame suited to support various other parts, at least one lower surface, at least one table suited to hold a workpiece and mounted on the lower surface, and at least one head with an electric tool-holding spindle, wherein the lower surface is inclined.

Claims

1. A numerical control machine comprising: a bearing structure-frame; a single support surface coupled to the bearing structure-frame and inclined in relation to a ground on which said bearing structure-frame is disposed; at least one table adapted to hold a workpiece and slidingly mounted on said support surface; and at least one head having an electric tool-holding spindle and configured to orient the tool-holding spindle in a plurality of directions, said head being coupled to a moving arm extending downwardly along a longitudinal axis that is perpendicular to the ground and that is disposed above said support surface in relation to the ground, said head being detached from said support surface, said directions including a direction inclined in relation to the ground, wherein said table and said head are disposed in relation to one another so as to enable said head to access and operate on each side of said workpiece by causing said table to slide along said support surface according to the side of said workpiece to be accessed and operated on, and by further causing said arm to dispose said spindle next to the side of said workpiece to be accessed and operated on.

2. The numerical control machine according to claim 1, further comprising at least one slide travelling on guides mounted on said support surface, wherein said table holding the workpiece is mounted on said slide.

3. The numerical control machine according to claim 2, wherein said guides are substantially oriented according to a direction of inclination of said support surface, so that said slide, when travelling, varies its height, thus positioning also said table at a desired height with respect to a position of said head.

4. The numerical control machine according to claim 3, wherein said guides are oriented according to a direction of maximum inclination of said support surface.

5. The numerical control machine according to the claim 1, wherein said table is at least adapted to rotate the workpiece about an axis perpendicular to the ground.

Description

(1) The characteristics of the new NC machine will be highlighted in greater detail in the following description, with reference to the attached drawing that is provided by way of non-limiting example.

(2) The attached drawing shows a practical embodiment of the invention by way of example without limitation.

(3) FIG. 1 shows the new NC machine.

(4) The new machine comprises a bearing structure (1) comprising a chamber (2) in which the workpiece (3), schematically shown in the FIGURE, is machined.

(5) The new machine comprises a lower surface (4), inclined with respect to the horizontal plane generically indicated as plane (X), and a head (8) provided with a tool-holding spindle (81).

(6) On said inclined lower surface (4) there is at least one guide (5) suited to allow the sliding movement of at least one slide (6), wherein said guide (5) is oriented in the direction of inclination of the lower surface (4), preferably in the direction of maximum inclination.

(7) A support or table (7) holding said workpiece (3) is mounted on said slide (6).

(8) Said table (7) is translated together with said slide (6) with respect to the inclined lower surface (4) and can thus be positioned at different heights, even higher than the position of said head (8).

(9) Said head (8) can thus orient the spindle (81) even in an inclined direction (X1) in order to machine the workpiece (3) from the bottom.

(10) Said support or table (7) holding said workpiece (3) is at least suited to rotate the workpiece (3) around a vertical axis (Y).

(11) These are the schematic outlines that are sufficient to the expert to implement the invention; consequently, when the invention is actually implemented variants can be produced that do not alter the substance of the innovative concept.

(12) Therefore, with reference to the above description and the attached drawing, the following claims are expressed.
