Diamond wire saw is a cutting tool that utilizes diamonds as the cutting medium. It consists of a flexible rope embedded with numerous small diamond particles, fixed by a high-strength steel wire. Diamond wire saws are known for their high efficiency, durability, and precision in cutting various hard materials, such as stones, concrete, and metals. They find wide applications in stone processing, construction, and mining industries. The cutting performance and lifespan of diamond wire saws depend on the quality of diamonds and the design of the wire saw structure.

The diamond beads in a diamond wire saw are typically composed of a mixture of diamond particles and metal powder. The ratio of diamonds to metal powder can be adjusted based on specific cutting requirements and application scenarios. Generally, the diamond concentration in the wire saw beads is relatively high, typically ranging from 30% to 40%. The concentration of metal powder, usually copper powder, is lower, typically ranging from 10% to 20%. This ratio ensures that the wire saw beads have sufficient cutting ability and wear resistance. However, the specific ratio and formulation may vary among different manufacturers and products.


When the diamond concentration is higher, the performance of the wire saw is reflected in the following aspects:


Cutting speed: A higher diamond concentration means a higher density of diamond particles in the wire saw, providing stronger cutting force and higher efficiency, resulting in faster cutting speed.


Wear resistance: Diamonds are one of the hardest substances on Earth, exhibiting excellent wear resistance. A higher diamond concentration enhances the wear resistance of the wire saw, enabling it to maintain a sharp cutting edge for an extended period, thus prolonging its lifespan.


Cutting quality: Wire saws with a higher diamond concentration offer more precise and smooth cutting surfaces, reducing the occurrence of fractures, debris, and burrs during the cutting process, resulting in higher cutting quality.


Versatility: Wire saws with a higher diamond concentration usually possess wider applicability, capable of handling different types of materials and cutting requirements, including high-hardness materials and complex cutting tasks.


However, it should be noted that a higher diamond concentration does not necessarily mean a better choice. When the diamond concentration exceeds 40%, the wire saw may encounter the following issues:


Rough cutting: Excessive diamond concentration may lead to rough and uneven cutting surfaces, with visible cutting marks and unsmooth edges.


Decreased cutting speed: Excessive diamond concentration may result in reduced cutting efficiency, slower cutting speed, and more time and effort required to complete cutting tasks.


Reduced lifespan: Excessive diamond concentration increases the contact area between diamond particles, leading to accelerated wear and reduced lifespan of the wire saw.


Decreased cutting quality: Excessive diamond concentration may generate more fractures, debris, and burrs during the cutting process, compromising the cutting quality and failing to achieve smooth and precise cutting results.


Decreased adaptability: Excessive diamond concentration may reduce the adaptability of the wire saw to different materials, especially when dealing with soft or fragile materials, increasing the risk of overcutting or damage.

In practice, the choice of diamond concentration should be balanced based on specific application scenarios and material characteristics to achieve optimal cutting performance and cost-effectiveness.
