DETAILED DESCRIPTION OF THE INVENTION

[0036] The present invention will now be illustrated by way of a non-limiting or non-binding example, with reference to the figures which illustrate several embodiments relative to the present inventive concept.

[0037] With reference to FIG. 1, the present grinding wheel 1 is shown which, in a preferred version, has a base flange 2 (made of iron, aluminum and/or resin, which ensures a rigid structure thereto). In such version, the aforesaid grinding wheel 1 comprises at least a cutting unit 2.1 provided with an internal diamond crown 2.2 which includes: [0038] a plurality of sensors for detecting the fine dust present in the air, [0039] a plurality of sensors adapted to signal a state of saturation of the surrounding air which allow the assigned personnel to move away from the operation area until healthy conditions of the environment surrounding the processing areas are re-established. [0040] a plurality of temperature sensors for signaling the increase of the temperature beyond certain limits which involves early wear of the tool.

[0041] The aforesaid diamond crown 2.2 comprises at least a central tooth 3: this allows removing the plastic material or similar materials, present on the sheets during processing.

[0042] The aforesaid central tooth 3 is produced by means of the sintering method or three-dimensional printing and is alternately: [0043] printed in a same entire block together with the entire device 1 by means of sintering process; [0044] made separately from the device 1, as a separate body (as shown in FIG. 7); in such conformation, this comprises a specific internal disc 3.1 to be flanged in a central portion of the aforesaid device 1 by means of a plurality of screws.

[0045] The particular characteristic of the central tooth 3 is that of allowing the removal and processing of portions of the glass sheets, in grinding step, by carrying out an incision such as a small thread in the internal part of the same glass sheets. The aforesaid central tooth allows various types of finishing and shapes in the processing of such sheets, including polished edge, raw edge and contributes to improving the structural strength performances of the glass itself by reducing the dimensions of the microlesions present on the edges of the sheets of the glass, adjacent to the plastic.

[0046] Such characteristic allows a use of glasses with smaller thickness but provided with a greater resistance to breakage and load.

[0047] The central tooth 3 maintains the profile of the entire device 1 functional over time, even after thousands of meters traveled, ensuring a high quality standard.

[0048] The aforesaid central tooth 3 is attained with a specific grain and mixture, which vary based on the plastic material to be removed, while its height and shape varies according to the thickness of the glass sheets and of the plastic material to be processed. Each central tooth 3 is made of shapes and materials, with cuts or serrations, adapted to remove the plastic material, based on the more or less rigid nature thereof.

[0049] To close the grinding wheel 1, at least an external flange 2.5 is placed as shown in FIG. 3. In addition there are compositions of glasses characterized by multiple glass sheets and plastic films, stratified, as an example glass 26/27 whose composition is: glass 8 mm+plastic 0.38+glass 10 mm+plastic 0.38+glass 8 mm; in the cases like that exemplified, on the diamond crown 2.2 at least two of the aforesaid teeth 3 are installed for removing the plastic at the same, for the cases in which the sheets adapted to for processing are composed of multiple layers.

[0050] As shown in FIGS. 5 and 6, on the aforesaid grinding wheel 1, a plurality of holes 2.3 are present which allow the passage of the water or of the coolant liquid and a cooling of the same; such holes 2.3 have variable dimensions based on the type of glass sheets and plastic material to be processed. In addition, a plurality of cuts and grooves 2.4 are present on the entire grinding wheel 1, variable based on the glass sheets and on the plastic material to be processed; such cuts and grooves 2.4 are attained in different configurations: inclined, straight, positioned on the entire surface of the cutting unit 2.1, and they provide for the removal of the plastic material by processing together with the aforesaid central tooth 3. The number and the type of the same are defined based on the thickness of the glass and plastic to be processed, but a greater number involves a greater fragmentation of the plastic, with benefits on the maintenance of the machinery.

[0051] The entire grinding wheel 1 is employed for the abrasion of the stratified solid materials and for the processing (grinding) of glass sheets, of ceramic glass and of any other material. This is made of any geometric shape, such as peripheral trapezoid profile, groove and any other shape, as well as on specific designs upon request of each customer, as well as in the sector version which allows the removal of the material in a single passage. Due to its particular characteristics, it optimizes the quality of the aforesaid sheets both from an aesthetic/functional standpointsince once the grinding has terminated, they are polishable and lacking plastic material residues on the edge of the sheetand from a technical/structural standpoint, since the processing of the edge of the glass adjacent to the plastic allows an increase of the structural load of the glass with respect to the same without such processing. The dimensions of the present device 1 vary by a diameter and a height comprised between 30 mm and 400 mm.

[0052] Finally, it is clear that modifications, additions or variations that are obvious for a man skilled in the can be made to the above-described invention, without departing from the protective scope that is provided by the enclosed claims.
