Wall saw having a locking device (41). A saw blade flange (25) of the wall saw is adjustable by the locking device (41) between a locked state and an unlocked state, wherein, in the locked state, the saw blade flange (25) is connected to the drive spindle (33) for rotation therewith, and, in the unlocked state, is adjustable in relation to the drive spindle (33). In the unlocked state of the saw blade flange, the drive spindle is blocked in the direction of rotation of the saw blade and is designed to be rotatable about the axis of rotation in a counter direction directed counter to the direction of rotation.

A powered saw assembly includes a base having a top surface, a column fixed to the top surface, and a guide rail supported above the top surface. The assembly includes a saw unit translatable along the guide rail, the saw unit including a rotating arbor to which a saw blade is attachable for co-rotation therewith. A blade guard at least partially surrounds the saw blade and defines an opening through which the saw blade is movable for attaching or removing the saw blade relative to the arbor. A cover is movably coupled to the blade guard to selectively close the opening. With the cover moved away from the blade guard to expose the opening, the saw blade is attachable or removable relative to the arbor through the opening without passing the saw blade through the slot.

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.

A method for controlling a wall saw system during the creation of a separating cut in a workpiece. The movement of the saw head is controlled at the end points such that a boundary of the wall saw facing the end point coincides with the end point after the pivoting movement of the saw arm. In the case of a free end point, the boundary of the wall saw is formed by an upper exit point of the saw blade. In the case of an obstacle, the boundary of the wall saw is formed by the saw blade edge of the saw blade if the processing occurs without the blade guard or by the blade guard edge of the blade guard if the processing occurs with the blade guard.

A method for controlling a wall system when creating a separating cut in a workpiece between a first and a second end point is disclosed. The wall saw system includes a wall saw having a saw head, a pivotable saw arm, a saw blade and a blade guard. The separating cut is carried out in a plurality of main cuts. The pivoting movement of the saw arm in a main cutting angle is carried out in at least two steps with at least one intermediate angle, where a free cut of the saw blade is carried out in the respective intermediate angle between the pivoting movements of the saw arm.

A method for controlling a wall saw system during creation of a separation cut in a workpiece between a first and second end point, where at least one of the end points is defined as an obstacle, is disclosed. The separation cut is carried out in a plurality of main cuts. In addition to a main-cut sequence, a corner-cut sequence having at least two corner cuts is defined for each end point defined as an obstacle. For each corner-cut sequence, a starting position and an end position are defined, the corner cuts being carried out therebetween. The wall saw is positioned in the starting position and is pivoted into a first corner-cut angle. Subsequently, the saw head is moved by way of the inclined saw arm until the end position has been reached. The wall saw is displaced back into the starting position and pivoted into a second corner-cut angle.

The separating cut is performed in a plurality of main cuts. The movement of the saw head is controlled at the end points such that a boundary of the wall saw facing the end point coincides with the end point. In the case of a free end point, the boundary of the wall saw is formed by an upper exit point of the saw blade.

Blade guard (20) configured to partially cover a rear face of a circular saw blade (9) while leaving a front face (9b) of the saw blade uncovered. The blade guard comprises: a guard plate (21) having an inner face (21a) configured to face the saw blade (9); and an elongated shielding unit (50) fixed to the guard plate (21) and configured to cover a part of the peripheral edge (14) of the saw blade.

The shielding unit comprises several shielding elements (52) arranged side by side along the shielding unit, each shielding element comprising a shielding member (53) and a resilient cantilever support member (54), wherein the shielding members are arranged side by side in a row in order to form an elongated barrier (55) capable of stopping cutting debris. The support members (54) allow the shielding members (53) to move in relation to each other and in relation to the guard plate (21).

A cover is movably coupled to the blade guard to selectively close the opening. With the cover moved away from the blade guard to expose the opening, the saw blade is attachable or removable relative to the arbor through the opening without passing the saw blade through the slot.
