The present disclosure provides a method for manufacturing a countertop, where a countertop workpiece may be easily secured to a workpiece-mounting device during the machining thereof, leading to good precision and standardization. This may be achieved using a suction of the countertop workpiece via air intake in the mounting device. Further, the present disclosure provides a countertop machining apparatus including a vacuum chamber divided into a multiple of vacuum sub-chambers disposed in a work table, and a suction panel disposed on the chamber. In this configuration, a number of the vacuum sub-chambers to be kept in a vacuum state may be adjusted. This may lead to a reduction of a power consumption required to suction the countertop workpieces.

A machine (12) for cutting slabs, comprises a workpiece support bench (14) adapted to support at least one slab, and cutting means for automated cutting of the slab on the bench. The cutting means comprise two lateral support structures (16, 18). A first beam (20) is adapted to move along said lateral support structures (16, 18). The first beam (20) is adapted to slide on the lateral support structures (16, 18) via its ends (22, 24) and guiding means (25, 26) provided on the lateral support structures (16, 18). The first beam (20) is provided with a first carriage (28) adapted to be moved along the first beam (20). A first sleeve (30) adapted to be moved towards or away from the workpiece support bench (14) is provided on the first carriage (28). A first machining head (32) comprising a first cutting spindle (34) is provided on the first sleeve (30). A second beam (201) is adapted to move along the lateral support structures (16, 18). The second beam (201) is adapted to slide on the lateral support structures (16, 18) via its ends (221, 241) and guiding means (26) provided on the lateral support structures (16, 18), independently of the first beam (20). The second beam (201) is provided with a second carriage (281) which is adapted to be moved along the second beam (201). A second sleeve (301) adapted to be moved towards or away from the workpiece support bench (14) is provided on the second carriage (281). A second machining head (321) comprising a second cutting spindle (341) is provided on the second sleeve (301). At least either one of the first head (32) and the second head (321) is provided with a gripping device (42, 421) for the slabs or parts thereof.

Various aspects of an apparatus are disclosed. In a particular aspect, an apparatus comprising a cylindrical filter, a filter cleaning knob, and a filter cleaning flap is disclosed. Within such embodiment, the filter cleaning knob is configured to rotate the cylindrical filter. The filter cleaning flap is coupled to the cylindrical filter and configured to sequentially make contact with a plurality of pleated segments of the cylindrical filter as the filter cleaning knob is rotated.

A novel cutting method and apparatus includes a cutting blade adapted to consistently and easily form a desirable kerf in a concrete substrate while capturing substantially all resulting concrete dust.

A tool-holder unit for machining block or slab materials is moveable above a working plane on which the block or slab material is laid. The tool-holder unit includes a spindle with a circular blade and a coupling assembly that couples a second machining tool with the spindle. The tool-unit further includes a tool-holder; a mechanical coupling device configured to rotationally integrate the tool-holder and the spindle; a first axial locking element configured to removably lock the tool-holder on the spindle; a substantially cylindrical shank extending from the tool-holder; a substantially cylindrical housing seat axially positioned in the spindle or a tool-holder coupling element; and a second axial locking element configured to removably lock the tool-holder in the spindle, the axial locking element being configured to removably lock the shank in the respective housing seat.

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 present invention relates to a guiding device for large-format manual cutters, said device consisting of a guide (1) that comprises: on its top surface (11) an intermediate recessed portion (111) delimited by a base (112) and by longitudinal rails (113a, 113b) for movement of a manual cutter (3); and, on opposite sides of its bottom surface, first support means (121, 122) for supporting the guide (1) on the part (P) to be cut and a longitudinal recess (123) for receiving lever suction cups (2) which form second means for supporting and securing the guide (1) on the part (P) to be cut. The longitudinal rails (113a, 113b) are arranged between the first and the second support means; and the first support means (121, 122) are arranged between the cutting tool (31) and the suction cups (2) which form the second support means.

A cutting system for slabs which includes a longitudinal guide having a pair of surfaces opposite to each other, the pair made up of a lower surface and an opposite upper surface, a suction cup coupled to the lower surface of the longitudinal guide suitable to selectively adhere to a slab and defining a contact surface of the longitudinal guide on the slab, the longitudinal guide further including a pair of rails parallel to each other coupled to the upper surface of the longitudinal guide and suitable for slidably coupling to a scoring slider. The rails are arranged on opposite sides with respect to a median plane of the suction cup perpendicular to the contact surface thereof.
