A machine (10) for grinding and/or polishing slabs of stone material, such as natural or agglomerated stone, ceramics or glass, comprises: a support bench (12) for the slabs to be machined. At least one working station (14) is provided above the support bench (12), said station comprising at least one pair of bridge support structures (16, 18) situated opposite each and arranged transversely on either side of the support bench (12). First means (19) are provided for performing a relative movement in the longitudinal direction of machining station (14) and slab on the support bench (12). The machine further comprises at least one beam (20, the two ends (22, 24) of which are supported by the support structures (16, 18), and at least one rotating spindle (26) with a sliding vertical axis mounted on the at least one beam (20). The beam (20) is movable transversely on the support structures (16, 18). The bottom end of the spindle (26) is provided with at least one tool-carrying support (28) rotating about the axis of rotation of the spindle (26). The machine is characterized in that it comprises second means (32) for performing a relative movement in the longitudinal direction of the at least one spindle (26) with respect to the support bench (12).

An apparatus for finishing a cut edge of a glass laminate includes a support including a surface and an edge, a rail disposed adjacent the support and extending substantially parallel to the edge, a carrier coupled to the rail, and a finishing tool coupled to the carrier and including an abrasive surface positioned adjacent the edge. Also provided arc various embodiments of a method.

A method for manufacturing a disk-shaped glass substrate is a method for manufacturing a disk-shaped glass substrate for cutting out one or more thin glass substrates. The method for manufacturing a disk-shaped glass substrate includes preparing a disk-shaped glass blank, which is a glass blank having two circular main surfaces, chamfering an outer edge portion of each of the two main surfaces of the disk-shaped glass blank, grinding the two main surfaces of the chamfered disk-shaped glass blank, using a double-side grinding apparatus, and polishing the two main surfaces of the ground disk-shaped glass blank, using a double-side polishing apparatus.

A method and apparatus for cutting a glass laminate. A trench line is formed in a glass substrate that is an uppermost layer of a glass laminate by scoring a surface of the glass substrate. The glass laminate is cut in the direction parallel to the trench line. It is possible to prevent the propagation of cracks commonly formed during the cutting of glass laminates.

An agglomerate glass surface product may include an agglomerate formed predominantly of glass aggregate having controlled proportions of different glass particle sizes bound by a cured thermoset binder infused within substantially all inter-aggregate voids. The agglomerate may be in the form of a pressed slab that is substantially non-porous and substantially devoid of air inclusions throughout an entire thickness of the slab. The glass aggregate may be substantially uniformly mixed with the thermoset binder throughout the entire thickness of the slab so as to be exposed at all surfaces of the slab. The agglomerate may have an overall aggregate content that is high enough to produce a slab surface that can be polished in the same manner and with the same machinery that natural stone is polished. Advantageously, the slab may have the look and feel of a natural stone slab. A related manufacturing method is also disclosed.

A glass treatment apparatus comprise at least one upstream working device including a working wheel configured to rotate such that a working surface of the working wheel machines a surface portion of a glass sheet. The glass treatment apparatus further includes a downstream working device includes a working wheel comprising a cleaning wheel. In further examples, methods of treating glass comprise the step of machining a surface portion of a glass sheet with a working surface of a first rotating working wheel and the step of machining the surface portion of the glass sheet with a working surface of a second rotating working wheel comprising a cleaning wheel.

A glass shaping method capable of grinding and/or polishing a fine brittle material more stably than conventional methods is provided. The glass shaping method of the present invention comprises: a mold forming step of shaping a surface of a base material having a higher melting temperature than a glass softening point to form a mold 10; a glass molding step of sealing softened glass into a groove 15 formed in a surface of the mold 10 by the forming step to mold a glass substrate 17; a glass processing step of cutting, grinding and/or polishing the glass substrate 17, with the mold 10 being fixed, to form a glass shaped article 1; and a step of eliminating only the base material 16 of the mold 10 after the glass processing step to remove the glass shaped article 1 from the mold.
