Disclosed is a frame for machines for cutting ceramic pieces, which comprises a support structure of a guide (G) for longitudinally moving a cutting head (C), which comprises: a central aluminium beam (1) and two lateral aluminium beams (2a, 2b), the beams having a tubular cross-section and being parallel and connected at opposite ends by means of respective steel end plates (3a, 3b); a detachable table formed by two aluminum profiles (4a, 4b) mounted on the central beam (1) and the lateral beams (2a, 2b); and steel corner pieces (5) attached to the support structure, there being mounted to the corner pieces respective pairs of foldable legs (6) provided with locking means (9) for locking in an unfolded position, respective reinforcing cross beams (10) for carrying shock-absorbing elements (11) and rear wheels (12) for transporting in a folded position.

A tile saw comprising a base, a table supported by the base and configured to support a workpiece, a guide rail upon which the table is supported and moveable along a longitudinal axis, a saw unit coupled to the base, and a roller assembly for supporting the table upon the guide rail. The roller assembly includes a first roller rotatably supported by the table and engaged with a first portion of the guide rail, and a second roller rotatably supported by the table and engaged with a second portion of the guide rail that is different than the first portion. The second roller is translatable relative to the table in a direction toward the guide rail. The roller assembly further includes a spring biasing the second roller toward the guide rail.

A material loading apparatus includes a movable material support surface that is pivotally mounted to the frame. The loading apparatus also includes a first link that extends between the support surface and the frame and is pivotally connected to the support surface at a first end of the first link and pivotally connected to the frame at a second end of the first link. The loading apparatus also includes a second link that extends between the support surface and the frame and is pivotally connected to the support surface at a first end of the second link and pivotally connected to the frame at a second end of the second link. The loading apparatus also includes an actuator that is pivotally connected to the frame and configured to move the support surface between a generally horizontal position and a generally vertical position.

A glass-plate working apparatus 1 includes a cutting section 2 serving as a processing position for forming cut lines on a glass plate 5, a grinding section 3 serving as a processing position for grinding peripheral edges of the glass plate 5, a bend-breaking section 4 serving as a processing position between the cutting section 2 and the grinding section 3, and a glass-plate transporting section 6 for transporting the glass plates 5, and further includes a feed conveyor 7 disposed on the side of carrying in to the cutting section 2 and serving as a glass-plate carrying-in section, as well as a discharge conveyor 8 disposed on the side of carrying out from the grinding section 3 and serving as a glass-plate carrying-out section.

The machine comprises: one base frame; one worktop for at least one slab, associated with the base frame; one cutting head adapted to cut the slab, associated with the base frame by interposition of one transverse frame moveable along a first direction, the cutting head being moveable on the transverse frame along a second direction transverse with respect to the first direction; gripping means of the slab, associated with the base frame and moveable sliding with respect to the base frame along the first direction; wherein the gripping means are associated with the transverse frame and moveable on it along the second direction independently with respect to the cutting head.

A sintered magnet sawing apparatus is provided comprising a cylindrical work carrier mounted on a horizontal rotating spindle and having a regular polygonal shape in a perpendicular cross section, and a plurality of endless elastic belts adapted to force a work of sintered magnet against the carrier surface to secure the work thereto and adapted to travel synchronously with and counter to the rotation of the carrier in a circulatory manner. In accordance with rotation of the carrier, the work is delivered to the peripheral surface of the carrier, secured thereto by the elastic belts, moved further forward and cutoff machined by an outer cutoff blade. The divided work is moved further forward, released and discharged from the carrier.
