The disclosed system may include a slicing component that has a cutting blade. The cutting blade may be configured to cut a semiconductor wafer into multiple wafer strips, where the wafer strips have flat top surfaces and multiple edges. The system may also include a chuck that has rotatable wafer plate strips that are respectively configured to support the wafer strips. The system may further include a pivot arm that rotates the chuck from a cutting position facing the slicing component to a rotated, polishing position that faces a polishing component. As such, an exposed edge of each wafer strip faces the polishing component. The system may also include a polishing component that is configured to polish at least a portion of the exposed edge of each wafer strip that is facing the polishing component. Various other methods, systems, and computer-readable media are also disclosed.

A dual platform bed system has an associated machine for transferring material sheets from one platform bed to another. There are associated methods for both transferring and processing sheets on either or both platforms. Placing the platform beds adjacent one another reduces both human worker requirement and human and machine down time.

An apparatus for cutting workpieces has a saw and a carousel. The carousel has a plurality of workpiece-holding pockets and is mounted for rotation about a carousel axis to pass the workpiece-holding pockets from a first position remote of the saw through at least a second position proximate the saw.

Working unit (1) for realizing holes (H) in a slab material (L) and for machining the inner side of the holes (H) thus formed, comprising a work table (2), at least one tool (4, 6) mounted on a motorized spindle, fixed means (8) for supporting the slab (L) and at least one support device (10) comprising a hollow element (11) intended to engage with a slab portion (P). The support device (10) comprises a top portion (12) movable at least between a raised position in which the slab portion (P) is coplanar with the slab (L) and a lowered position in which the slab portion (P) is lowered with respect to the slab (L) and therefore the hole (H) is free of the slab portion (P). The support device (10) comprises means (14) for locking the movable top portion (12) at least in the lowered position.

A combination cart providing independent electrical power generation and dust extraction capabilities finds utility in concrete processing and other operations that create unwanted dust using hand tools for cutting, grinding, polishing, coring, drilling, sanding, and the like. A propane tank powers a propane engine, and the propane engine drives an electrical generator providing power to an electrical outlet panel mounted on the frame. The cart further includes a dust extraction and filtration system driven by an electric motor, also mounted on the frame. The inventive cart facilitates multiple modes of operation, including: (a) dust extraction and filtration only, with the dust extraction system being powered by an available external source of electrical power; (b) electrical power generation only, with the dust extraction and filtration system being turned off; and (c) simultaneous dust extraction/filtration and electrical power generation, with the dust extraction and filtration system being powered by the electrical generator.

Machine for the surface processing of products (L) under controlled pressure conditions different than the ambient pressure, comprising • at least one sealed chamber (12, 13), provided with at least one opening (15, 16), that can be closed, for inserting and removing a plurality of products (L) to be processed, • a device (30) for adjusting the pressure inside said at least one chamber (12, 13), • in said at least one chamber (12, 13), a moving device (20) for vertically moving said products (L), so as to accumulate at least two said products on levels arranged over one another, • a horizontal moving device (19) for moving said products (L) from and towards said at least one opening (15, 16) when the products (L) are arranged at the same level of said at least one opening (15, 16) wherein, from an operational viewpoint, a plurality of said products (L) are inserted into said at least one chamber (12, 13), and at least two products of said plurality of products (L) are over one another for a span of processing, and wherein, once all the products to be processed have been inserted into said at least one chamber, (12, 13) said chamber (12, 13) is closed and the pressure inside is adjusted up to an operational processing pressure, and then said at least one chamber (12, 13) is opened again and the products (L) are removed therefrom.

Machine (1) for processing slabs (L) comprising a device (14) for transporting the slabs (L) between two zones, at least one of which is a machining zone along a feeding direction (X), means (16, 17) for supporting and clamping the slabs during machining, said means being designed to clamp the slabs (L) in a machining position, at least one tool (4) for machining the slabs which is mounted on a spindle, the at least one tool (4) being operative in the machining zone. The machine (1) comprises means (50) for moving the transporting device (14), configured to move the transporting device (14) from a working position corresponding substantially to the position for machining the slabs (L) into a position spaced at least vertically from the working position, and vice versa; the transporting device (14) is a conveyor belt.

According to a processing method of a stone composite board, the two sides of a natural stone board are ground and flattened until a preset standard value of thickness variation is reached, then the surface planes and base material layers are subjected to pressure-compositing through adhesive layers, afterwards splitting is conducted, and the natural stone layer is subjected to calibrated planing with diamond roller and surface treatment to obtain the ultra-thin stone composite board.
