A wire saw includes a U-shaped cutting area. An endless sawing wire loop runs between a plurality of wire pulleys including at least two displaceable cutting area pulleys, displaceable wire tensioning pulleys and wire plane changing pulleys. The endless wire loop defines a first cutting area plane P1 in the U-shaped cutting area and at least one further wire loop plane dissimilar from the first cutting area plane. The wire plane changing pulleys guide the sawing wire between the first cutting area plane and the further wire loop plane P2. A wire driving pulley is driven by a wire drive motor. A cutting area pulley actuator runs the cutting area pulleys along each side of the workpiece cutting area. The displaceable wire tensioning pulleys are displaceable by at least one tensioning actuator within the further wire loop plane P2 to maintain a tensioned sawing wire.

Methods for controlling the surface profiles of wafers sliced from an ingot with a wire saw include measuring an amount of displacement of a sidewall of a frame of the wire saw. The sidewall is connected to a bearing of a wire guide supporting a wire web in the wire saw. The measured amount of displacement of the sidewall is stored as displacement data. Based on the stored data, a pressure profile for adjusting a position of the sidewall is determined by a computing device. Pressure is applied to the sidewall using a displacement device according to the determined pressure profile to control the position of the sidewall.

A crawler type crane having a base carrier unit having a control unit associated therewith and an upper portion assembly having a boom portion coupled at end to the base carrier unit and to a jib portion at an opposed end. The boom portion includes one or more selected boom sections that are articulatable relative to each other. The crane also includes a multi-function attachment unit that is coupled to the jib portion and has a grappling unit for grasping a work piece and a saw attachment unit for cutting the workpiece. The crane can also include a first fluid regulating device coupled to the jib portion for regulating a fluid to the jib portion and to the multi-function attachment unit and a second fluid regulating device coupled to the boom portion for regulating a fluid to the winch element and to the multi-function attachment unit.

A circular saw blade includes a circular plate having a diameter, a thickness, a left face, a right face, a peripheral rim, and a central opening. A plurality of alternating teeth and gullets are disposed about the peripheral rim, each tooth having a front face facing generally toward an adjacent gullet in the cutting direction and a recess defined in the front face. A plurality of cutting inserts are affixed in the recesses in the teeth. Each insert has rake face facing generally toward the adjacent gullet in the cutting direction, a relief face extending generally toward the adjacent top face, and a cutting edge at a junction between the relief face and the rake face. Each rake face is disposed at a hook angle. The relief faces include unbeveled relief faces, left-beveled relief faces, and a right-beveled relief faces arranged in an alternating top bevel with raker pattern.

The invention relates to a wire management system (7) for a wire saw (8) having a cutting wire (3) which is guided through a cutting area (13), the wire management system (7) comprising a wire supplying unit (5) for supplying cutting wire (3) to the cutting area (13) of the wire saw (8) and a wire receiving unit (6) for receiving cutting wire (3) from the cutting area (13) of the wire saw (8), wherein at least one of the wire supplying unit (5) and the wire receiving unit (6) comprises: at least one rotatable reservoir spool (1) for carrying the cutting wire (3) in overlapping windings, at least one rotatable storage spool (2) for temporarily receiving the cutting wire (3) in windings, wherein the rotational axis (2b) of the storage spool (2) coincides with the rotational axis (1 b) of the reservoir spool (1), a wire guiding means (9) for guiding the cutting wire (3) when being wound up on the storage spool (2), such that the wire windings on the storage spool (2) do not overlap each other and/or have a lower density than the windings on the reservoir spool (1).

A wire guide roll for use in wire saws for simultaneously slicing a multiplicity of wafers from a cylindrical workpiece is provided with a coating having a thickness of at least 2 mm and at most 7.5 mm of a material which has a Shore A hardness of at least 60 and at most 99, and which contains a multiplicity of grooves through which the sawing wire is guided, the grooves each having a curved groove base with a radius of curvature which is 0.25-1.6 times the sawing wire diameter, and an aperture angle of 60-130. A multiplicity of wafers are simultaneously sliced from a cylindrical workpiece by a wire saw using such wire guide rolls.

A method for cutting a starting panel of mineral wool or porous construction material into several panels includes supplying a starting panel having a front edge and cutting the panel into two in its thickness by a wire by moving the panel in a direction (X). The wire passes in a direction (Y) perpendicular to the direction (X) to form two first panels. The method also includes cutting the rear edge of the two first panels and the front edge of two second panels by moving the wire in a direction (Z) perpendicular both to the direction (X) and to the direction (Y), cutting the panel into two in its thickness using the wire by moving the panel in the direction (X) to form the two second panels, and repeating the cutting front/rear edges and cutting in the thickness to form two third, fourth, etc. panels.

A wire saw having a wire drive and a wire store for a saw wire, in which an actuating device for tautening the saw wire is arranged on a drive and storage unit of the wire saw. Also provided is a system made up of a wire saw and a remote control device, wherein the actuating device is a constituent of the remote control device. The invention relates to a method, and to the use of an actuating device for tautening a saw wire in a wire saw, wherein the actuating device is arranged on a drive and storage unit of the wire saw or is a constituent of a remote control device.

Generally described, the systems and methods disclosed in herein relate to sectioning an object with a frame-mounted wire saw as the step of a method for recycling fiber composite source objects, such as wind turbine blades. The frame-mounted wire saw generally includes a support frame assembly and a pulley system for directing an abrasive wire from a wire saw. A pair of slidable pulleys directs the abrasive wire through the object as the abrasive wire cuts. In some examples, the frame-mounted wire saw includes a mobility system to allow the assembly to travel along the length of the object and position the frame-mounted wire saw for the cut.
