Wire Saw Cutting

Wire Saw Cutting – Detailed Overview



What Is Wire Saw Cutting?



Wire saw cutting is a diamond wire cutting technique used to slice through very thick or complex concrete, steel, or stone structures. It employs a continuous loop of diamond-embedded cable (wire) that is tensioned and pulled through the material. Wire sawing is extremely versatile, capable of cutting in any orientation or shape, and is ideal for large-scale or irregular cuts where conventional saws can’t reach.





Primary Uses of Wire Saw Cutting



1. Cutting Massive or Thick Structures





  • Ideal for heavily reinforced concrete thicker than 800 mm, where wall or floor saws are insufficient.




  • Cuts bridge piers, large columns, foundations, dams, and reactor walls.





2. Controlled Demolition





  • Allows for precise sectioning of large structures for removal without using impact tools or explosives.




  • Frequently used in structural dismantling and retrofit projects.





3. Irregular Shape or Angle Cuts





  • Unlike blade saws, wire sawing can cut curved, sloped, or round profiles.




  • Ideal for circular openings, custom shapes, or angled cuts.





4. Cutting in Confined or Remote Spaces





  • The flexible wire can be looped through or around hard-to-access objects.




  • The drive system can be set up remotely, making it perfect for tight or hazardous environments.





5. Cutting Steel and Composite Materials





  • Cuts through concrete-encased steel, steel beams, or mixed materials without switching tools.




  • Used in nuclear plants, oil refineries, and industrial installations.





6. Underwater and Submerged Cutting





  • Wire sawing is highly effective underwater due to its non-impact, vibration-free method.




  • Used for offshore platforms, submerged piers, and underwater pipelines.







Wire Saw Cutting Equipment & Process



Equipment:





  • Diamond wire with embedded industrial diamonds




  • Drive pulley and flywheels




  • Hydraulic or electric motor




  • Cooling water system





Process:





  1. Drill Access Holes: If necessary, for threading the wire through or around the material.




  2. Loop the Wire: The diamond wire is looped through or around the cutting path.




  3. Setup Drive & Tension: Connect the wire to a powered drive system that pulls it in a continuous motion.




  4. Cutting Begins: The wire moves at high speed, grinding through the material while water cools and reduces dust.




  5. Section Removal: Once cut, the section is lifted and removed using cranes or rigging.
