Abstract
An apparatus for machining an article (L) in the form of a slab or the like comprises—in addition to a rotary tool (24) associated with a spindle (22)—a nozzle (26) ejecting water at very high pressure. Both the rotary tool and the nozzle are supported by a carriage (20) sliding along a beam (18) in turn sliding along two shoulders (14) in a perpendicular direction. In the working area (12) and above a tank (30) normally filled with water, the article (L) is supported in a horizontal position not only by an interchangeable grid (32; 52), but preferably also by a disposable support (34) which prevent the rotary tool (24) from coming into contact with the grid. The disposable support is periodically replaced.
Claims14
A combined numerical-control apparatus, with interpolated axes, for machining an article manufactured from solid stone, glass, ceramic or metallic materials, in particular a slab, the apparatus comprising:
- a frame delimiting a working area of the article and formed by two shoulders and a beam perpendicular the shoulders and slidable along the shoulders;
- a spindle and an associated rotary tool movable vertically to engage the article within the working area;
- a carriage sliding along the beam for supporting the spindle, the carriage being movable in a controlled manner with respect to the article in two horizontal directions perpendicular to each other;
- a water emission nozzle for water cutting, the nozzle supported by the carriage;
- a tank normally full of water inside the working area;
- means for bringing the water to the desired pressure;
- means for supplying the water emission nozzle with the water;
- means for supporting the article in a horizontal position during machining within the working area above the tank,
- wherein the means for supporting the article during machining within the working area, above the tank, consists of an interchangeable grid and disposable support means arranged between the grid and the article, the disposable support means having the function of preventing the rotary tool from coming into contact with the grid.
A plant for processing articles in the form of a slab, the plant comprising:
- a combined apparatus, the combined apparatus comprising
- a frame delimiting a working area of the article and formed by two shoulders and a beam perpendicular the shoulders and slidable along the shoulders;
- a spindle and an associated rotary tool movable vertically to engage the article within the working area;
- a carriage sliding along the beam for supporting the spindle, the carriage being movable in a controlled manner with respect to the article in two horizontal directions perpendicular to each other;
- a water emission nozzle for water cutting, the nozzle supported by the carriage;
- a tank normally full of water inside the working area;
- means for bringing the water to the desired pressure;
- means for supplying the water emission nozzle with the water;
- means for supporting the article in a horizontal position during machining within the working area above the tank,
- wherein the means for supporting the article during machining within the working area, above the tank, consists of an interchangeable grid and disposable support means arranged between the grid and the article, the disposable support means having the function of preventing the rotary tool from coming into contact with the grid;
- a conveyor means able to ensure the transfer of the article, arranged above the disposable means, if present, into the working area of the combined apparatus above the tank and the removal of the resultant articles.
