Wire saw

Wire saws cut up pieces, mostly large solid objects such as natural stones driven by electric motors Sägeseilen. Today often diamond wires are used which are held at short intervals with annular diamond segments. The Diamantseilsäge was first used in 1984.

Areas of application

The use of a wire saw is there sense to split where the object is inaccessible or is in a particularly difficult position in space. A common application is the isolation of structures before ascending capillary. To this end, the masonry is cut gradually horizontally by means of a wire saw and subsequently filled with water- separating materials again.

Another area of ​​application opens up for wire saws when a straight and in the contour precisely defined cut-out is required from structural engineering reasons, for example in steel reinforced components.

Wire saws are also used in the salvage of shipwrecks, ie for cutting of steel, for example, in the recovery of the car carrier Tricolor or the nuclear-powered cruiser K -141 Kursk.

Sägetechnik

Thanks closure - - endless cable via deflection rollers driven by a drive unit with an electric motor is a. The cutting speed of the cutting wire is slowly ramped up after sawing start until the required cutting speed. The cutting performance of the diamond saw, depending on the material between 8 to 16 m / hr.

The drive unit is added continuously and holding the rope in tension. Inside of diamond wires, there is a steel cable that is strung to about 8 mm in diameter measured round " carbide beads ". The spacing of the carbide beads is about 2.5 inches, and they are filled with artificial and natural small diamonds. The diamond wires are cooled with water at Sägeeinsatz. They vary in length depending on the requirement. The diamond beads were formerly held with steel springs at a distance, today there are plastic sleeves.

To the quarry before the sawing wire is inserted, a horizontal and a vertical hole to run the meet exactly. In these holes the rope is introduced and then the rope ends are screwed.

Wire saws perform the following tasks:

  • Quarries: Rough blocks are extracted from the Quarry with the Diamantseilsäge and Helikoidalsäge from the bedrock
  • Stone working industry: cutting of contours ( with oversized jigsaws comparable) the so-called tranches (large format unbekantete plates from about 8 cm thickness and up) are possible. For mechanical engineers developed the Konturenseilsäge whose swiveling saw unit allows a high degree of freedom for the design of a blank.
  • Stone processing operations: addition, be used for simple wire saws to saw off individual tranches of the stone blocks of stone blocks that are too long for the frame saw, or small orders.

Wire sawing in concrete

In the field of concrete sawing technology is taken to bring even greater cut-outs or special forms into a workpiece. The wire saws, a distinction here between normal and sickle wire saws. Normal wire saws are used to square openings to bring in concrete, or to realize other forms. Circles wire saws are used for large round openings at the other methods are not practical. (Diameter greater than 1 meter in most cases) or if the places are very inaccessible.

The diamond -studded wire saw is this driven electro - hydraulically and cooled with water due to the heat.
