Method for controlling a wall saw system when making a separating cut
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.
Circular saw apparatus with integrated multistage filtration system
Various dust collection apparatuses are disclosed, which include a vacuum source, a circular saw blade, and a worktable comprising a center slot axially aligned to the circular saw blade. In a first aspect, the center slot includes an air flow channel proximate to an anticipated point of contact between the circular saw blade and a workpiece, and the vacuum source is configured to provide a focused negative pressure beneath the worktable via the air flow channel. In another aspect, the vacuum source provides a negative pressure beneath the worktable at the center slot, and a multistage filter is included to collect airborne dust drawn by the negative pressure from an area proximate to the center slot. In yet another aspect, the vacuum source is configured to provide a first negative pressure beneath the worktable at the center slot, and a second negative pressure via an auxiliary port.
DEVICE SYSTEM INCLUDING A RADIO LINK
A device system, including a remote control (13) having a device housing (31) and a first radio unit (38), a tool device with a second radio unit and a radio link which connects the first radio unit (38) of the remote control (13) to the second radio unit of the tool device. The first radio unit is (38) is arranged on a front side (57) of the device housing (31), wherein the front side (57) is lying opposite a rear side (56) of the device housing (31) facing the operator in a working position of the remote control (13).
Tile cutter with collapsible cutting head assembly
A tile cutter includes a base, and a cutting head assembly including a supporting arm having one end pivotally connected to the base and an opposite end connected to the saw base for enabling the cutting head assembly to be biased relative to the base and selectively positioned in a standby position, a cutting position or a received position. When shifting the cutting head assembly from the standby position to the cutting position, the supporting arm is received by a stopper to limit the cutting depth of the cutting head assembly. When shifting the cutting head assembly from the cutting position to the received position, the stopper is moved to release the supporting arm. When the cutting head assembly is shifted to the received position, a part of the saw base and the saw blade are received in a sink in the base.
Device system including a radio link
A device system, including a remote control (13) having a device housing (31) and a first radio unit (38), a tool device with a second radio unit and a radio link which connects the first radio unit (38) of the remote control (13) to the second radio unit of the tool device. The first radio unit is (38) is arranged on a front side (57) of the device housing (31), wherein the front side (57) is lying opposite a rear side (56) of the device housing (31) facing the operator in a working position of the remote control (13).
JOINT SAWING SYSTEM FOR CONCRETE BARRIERS
A system and a method for sawing control joints in concrete barriers is provided. The system includes a barrier mounting frame slidably mountable about the barrier, on the top, first and second lateral faces of the barrier. The system also includes a saw attachment having a circular saw attached thereto, the circular saw being manually operable. A linkage assembly connects the frame mounting barrier to the saw attachment, and allows to manually move the circular saw up or down, and towards or away from the barrier, when in use, to create the control joint transversally along the top, first and second lateral faces of the barrier.
Skid Steer Cutting Attachment
Cutting apparatus attachable to a skid steer. The apparatus includes a house attached to a skid steer. The house is attached to an arm, which is attached to a motor that drives a blade. A single hydraulic circuit originating from the skid steer powers both the motor and a cylinder that is capable of pivoting the arm or rotating a guard that partially surrounds the blade. The user is able to operate the motor and cylinder independently of one another. The cutting apparatus is capable of cutting a straight line on horizontal, raised, and vertical surfaces.
Method for Controlling a Wall Saw System During the Creation of a Separation Cut
A method for controlling a wall saw system during creation of a separating cut in a workpiece is disclosed. The wall saw system includes a saw head, a pivotable saw arm, a first saw blade, and a larger second saw blade. The separating cut is performed in a plurality of main cuts, where the parameters of the main cuts (saw blade diameter of the saw blade used, main-cut angle) are defined before the start in a main-cut sequence. After the processing of the separating cut by the first saw blade is concluded, the controlled processing of the separating cut is interrupted by a control unit and the wall saw is moved into a parking position such that all actions of the saw-blade change (swinging out the saw arm, removing the first saw blade, installing the second saw blade, and swinging in the saw arm) can be performed.
Tile or masonry saw assembly with improved blade wetting capability
A tile or masonry saw assembly may include a saw and a frame. The saw includes a motor operable to turn a blade of a blade assembly to cut a workpiece. The blade assembly is internally wetted during operation by nozzles disposed on opposing sides of the blade to provide water onto the blade within a blade guard configured to shield a portion of the blade. The frame is operably coupled to the saw to support the workpiece. The frame supports a water collecting system for collecting the water. The water collecting system includes a water tank that is removable from the frame.
TILE SAW
A tile saw includes a base, a frame assembly disposed on the base, a first rail disposed on the frame assembly, the first rail having a longitudinal axis, a table slidingly disposed on the first rail, a support assembly disposed on the base, a saw assembly supported by the support assembly, the saw assembly comprising a motor, a cutting wheel driven by the motor, the saw assembly being pivotable about a horizontal axis substantially parallel to the longitudinal axis, and a switch electrically connected to the motor and disposed on the support assembly so that, when the motor assembly is pivoted about the horizontal axis, the switch remains stationary.
