An angle guide assembly for being coupled to a table body that slides along a longitudinal axis relative to a base of a saw. The angle guide assembly includes an attachment member configured to attach the angle guide assembly to the table body; a guide body and an angled fence pivotally coupled to the guide body between a first orientation in which a workpiece can be placed at an angle to the longitudinal axis along a first guide surface of the guide body by placing the workpiece against the fence surface, and a second orientation in which a workpiece can be placed at an angle to the longitudinal axis along a second guide surface of the guide body by placing the workpiece against the fence surface.

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 wet cutting saw for cutting a ground portion, the wet cutting saw including a blade rotatable about an axis, a liquid feed conduit for feeding liquid onto a surface of the blade as it rotates, a frame for carrying the blade and configured to travel over a surface of the ground portion, and a mounting assembly that mounts the blade to the frame, at least part of the mounting assembly pivotable relative to the frame to raise and lower the blade relative to the frame.

A cutting arm assembly used in a tile cutter is disclosed to include a swing arm pivotally connected with a bottom end thereof to a worktable and having first and second through holes disposed near an opposing top end thereof, a first supporting tube having one end thereof affixed to a saw-cutting device and an opposite end thereof fastened to the first through hole of the swing arm with a first mounting device set, and a second supporting tube having one end thereof affixed to the saw-cutting device and an opposite end thereof fastened to the second through hole of the swing arm with a second mounting device set. Thus, the cutting arm assembly has a simple structure capable of providing excellent support to the saw-cutting device and facilitating installation and maintenance.

A concrete pile cutting assembly configured for cutting a concrete pile includes a cutting saw portion supported on a collar portion. The collar portion securely engages the concrete pile and mounts the cutting saw portion adjacent the concrete pile at a desired height such that a cutting blade of the cutting saw portion cuts, or severs, the concrete pile at the desired height. The collar portion includes a plurality of collar elements each having a beam, a connecting flange, and a locking fastener. The locking fastener of a first beam engages with a corresponding beam opening of a second beam to connect adjacent collar elements together. Each beam has at least one mounting cylinder and the cutting saw portion includes a post for engaging with one of the mounting cylinders provided on the beams to mount the cutting saw portion onto the collar portion.

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.

A method for controlling a wall saw system during creation of a separating cut in a workpiece between a first and a second end point is disclosed. 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. 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 saw system during the creation of a separating cut in a workpiece between a first and a second end point is disclosed. 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 after the pivoting movement of the saw arm into the main-cut angle of the following main cut. For a free end point, the boundary of the wall saw is formed by an upper exit point of the saw blade. For an obstacle, the boundary 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 saw system during creation of a separation cut in a workpiece between a first and second end point, is disclosed. The separation cut is carried out in a plurality of main cuts. In addition to the main-cut sequence, an overcut sequence having at least two overcuts is defined for each end point defined as a free end point. For each overcut sequence, a starting position and an end position are defined, the overcuts being carried out therebetween. The wall saw is positioned in the starting position and is pivoted into a first overcut 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 overcut angle. This sequence is repeated until all of the overcuts have been carried out.
