Abstract
A grinding assembly (3) is described, for a grinding head (1) for a grinding machine of glass slabs (2), comprising: a first (5) (and possibly a second (7)) grinding wheel adapted to tangentially work on the glass edge (2) and whose rotation axis A is parallel to the glass edge (2) to be ground; and a handling system for the grinding wheel (5) for adjusting the removal of glass (2) in an oscillating way or in parallel with the plane of the slab (2) to be ground. A grinding head (1) equipped with the above grinding assembly (3) is further described.
Claims9
A grinding assembly for a grinding head for a grinding machine for glass slabs, the grinding assembly comprising:
- at least one first grinding wheel adapted to tangentially work on an edge of the glass slab and whose rotation axis is parallel to the edge of the glass slab to be ground;
- and
- a handling system for the first grinding wheel adapted to move the first grinding wheel to remove glass from the glass slab through oscillations or in parallel with the plane of the glass slab to be ground.
A grinding head for a grinding machine for glass slabs comprising:
- a supporting structure;
- at least one first grinding wheel for laterally grinding the glass slabs, the first grinding wheel being supported and rotatingly driven by a first spindle, the first grinding wheel and the first spindle being contained in and supported by the supporting structure;
- at least one second grinding wheel for grinding upper threads of the glass slabs, the second grinding wheel being supported and rotatingly driven by a second spindle, the second grinding wheel and the second spindle being contained in and supported by the supporting structure;
- at least one third grinding wheel for polishing the upper threads of the glass slabs, the third grinding wheel being supported and rotatingly driven by a third spindle, the third grinding wheel and the third spindle being contained in and supported by the supporting structure;
- at least one fourth grinding wheel for grinding lower threads of the glass slabs, the fourth grinding wheel being supported and rotatingly driven by a fourth spindle, the fourth grinding wheel and the fourth spindle being contained in and supported by the supporting structure;
- at least one fifth grinding wheel for polishing lower threads of the glass slabs, the fifth grinding wheel being supported and rotatingly driven by a fifth spindle, the fifth grinding wheel and the fifth spindle being contained in and supported by the supporting structure;
- and
- at least one sixth grinding wheel for laterally polishing the glass slabs, the sixth grinding wheel being supported and rotatingly driven by a sixth spindle, the sixth grinding wheel and the sixth spindle being contained in and supported by the supporting structure;
- the first grinding wheel and the sixth grinding wheel rotating, in a mutually independent way, around an axis that is perpendicular to an edge of the glass slabs, the second, third, fourth and fifth grinding wheels rotating, in a mutually independent way, around an axis that is slanted with respect to the edge of the glass slabs, the second, third, fourth and fifth grinding wheels being adapted to perform, when working, an axial movement along the glass slabs, the axial movements of the second, third, fourth and fifth grinding wheels being adapted to be activated independently one from the other, wherein the grinding head further comprises at least one grinding assembly.
