A method for using a vehicle-mounted wire saw for cutting an object (such as a wind turbine blade) includes coupling a wire saw having a continuous abrasive wire to a vehicle, engaging a wire tension to between about 100 PSI and about 5000 PSI, engaging a speed of an engine of the vehicle to between about 500 RPM and 4000 RPM, and cutting the object with the wire saw.

A cutting apparatus and the method of operating same is provided. The apparatus includes a feed tower assembly configured to be attached to an object and a frame assembly movably attached thereto. The frame assembly has arm assemblies thereon which accept a cutting member. A liquid spray system is provided for cooling components of the cutting apparatus.

A device for cutting a plate or panel of porous construction material includes a movement structure that moves the plate or panel and includes at least one conveyor, and which is able to move in a direction (X). The device also includes a wire to cut the plate or panel and a structure for passing the wire in a direction (Y) perpendicular to the direction (X) of travel of the plate or panel. The device for cutting allows a cut to be made that greatly limits the waste and dust generated.

A method for sawing a metal tube (3) or a hollow section is disclosed. The method includes using a band-saw machine, which has a stationary lower saw part (1), having a saw table (2) for securing the metal tube (3) or the hollow section to be sawn, and an upper saw part (4), which is movable in relation to the lower saw part (1) and which has a revolving saw band (5). The revolving saw band (5) penetrates the metal tube (3) or the hollow section via a feed motion (13) of the upper saw part (4), which is performed in relation to the lower saw part (1). For performing a saw cut, the revolving saw band (5) is guided through the metal tube (3) or the hollow section. The feed motion is carried out substantially counter to the force of gravity.

A multiplicity of wafers are simultaneously cut from an ingot by means of a structured sawing wire, wherein the structured sawing wire is guided through grooves of two wire guide rolls, and a bottom of each groove, on which the structured wire hears, has a curved groove bottom with a radius of curvature which, for each groove, is equal to or up to 1.5 times as large as the radius of the envelope of the structured wire which the structured wire has in the respective groove.

The present invention relates to a reciprocating wire saw device. The device is primarily comprised of a body with at least one handle, at least one trigger, at least one battery, and a second end with at least one blade and at least one plunger. The device preferably has two oscillating arms that oscillate independently via the motor. Therefore, each end of a wire blade can be attached to each arm such that oscillation of the arms allow the blade to cut a pipe or other similar object.

A dust collection system comprises: a cover configured to hermetically seal nuclear power plant structure, which is a target to be cut, the cover being provided at an outer circumferential surface thereof with a plurality of cutting groove members adjusted for a height of the cutting wire, the cover being made of a transparent material; an air compressor configured to supply compressed air; an air hose configured to convey the compressed air; a passage member provided in each of the plurality of cutting groove members, the passage member being configured to receive the compressed air such that the compressed air is sprayed to the cutting wire through the cover made of the transparent material; a packing member configured to wrap at least a part of an inner circumferential surface of each of the plurality of cutting groove members.

A cutting apparatus and the method of operating same is provided. The apparatus includes a feed tower assembly configured to be attached to an object and a frame assembly movably attached thereto. The frame assembly has arm assemblies thereon which accept a cutting member. At least one arm assembly can be pivoted relative to the other arm assembly and relative to the feed tower assembly. One arm assembly can further be moved relative to the other arm assembly and relative to the feed tower assembly in a vertical direction.

The invention relates to a wire management system for a wire saw having a cutting wire guided through a cutting area. The system comprises a wire supplying unit for supplying cutting wire to the cutting area and a wire receiving unit for receiving cutting wire from the cutting area. At least one of the wire supplying unit and the wire receiving unit comprises: at least one rotatable reservoir spool for carrying the cutting wire in overlapping windings, at least one rotatable storage spool for temporarily receiving the cutting wire in windings, wherein the rotational axis of the storage spool coincides with the rotational axis of the reservoir spool, a wire guiding means for guiding the wire when being wound up on the storage spool, such that the wire windings on the storage spool do not overlap each other and/or have a lower density than the windings on the reservoir spool.

A diamond wire cutter, using an adjustable length pulley system, a diamond wire saw, and a movable pulley cart, can perform a through-cut of complete sections of a structure such as a tubular subsea by fitting a chain about an outer surface of the structure, securing the chain to the movable pulley cart and using the chain to move or otherwise guide the movable pulley cart about the outer circumference of the structure to cut while using a diamond wire to effect a cut between the movable pulley cart and the diamond wire saw.
