The Difference of

Reeled Diamond Wire Saw And Endless Wire Saw

The primary differences between the conventional reeled diamond wire saw used in the SGO 20 machine and an endless (or loop) diamond wire saw can be explained through several key aspects:

1. Wire Configuration:

  • Diamond Wire Saw (SGO20):
    • This machine typically uses a long, straight diamond wire that is threaded through the machine and workpiece. The wire is moved back and forth or continuously in one direction for cutting. The wire is wound on a spool, fed through the cutting area, and then collected on another spool after cutting. and controlled by the feed and tension mechanisms.
  • Endless Diamond Wire Saw:
    • The endless diamond wire is a closed loop, meaning it forms a continuous loop (usually around 10 meters in length) and rotates in one direction at high speed. There is no need to reverse the direction of the wire, which allows for faster linear speeds (up to 80 m/s), leading to higher efficiency and smoother cutting surfaces without wire marks.

2. Wire Length:

  • Diamond Wire Saw (SGO20):
    • This machine uses a longer wire (can hold up to 200 meters of wire), suitable for specific applications and varied workpieces. The wire is gradually consumed during cutting.
  • Endless Diamond Wire Saw:
    • The wire is a shorter, continuous loop (typically around 10 meters), providing consistent tension and cutting speed over the entire process. This loop system enhances precision and reduces wear compared to longer wires.

3. Cutting Speed , Efficiency and Surface Qualit:

  • Diamond Wire Saw (SGO 20):
    • Wire speed is generally slower, around 0–11 m/s depending on the material, with adjustable speeds to control the cutting process.
    • Effective for a range of applications but might leave wire marks on the cut surface, especially in slower cutting processes or with softer materials.
    • Frequent wire direction changes can affect the speed to be lower.
  • Endless Diamond Wire Saw:
    • Higher wire speeds, up to 80 m/s, are achievable, resulting in faster cutting and smoother surfaces. Since there is no need to change the running direction, the cutting process is more efficient and leaves a finer finish.
    • Cut speed normally can be several times faster than conventional diamond wire saw.because The continuous one-way motion allows the wire to operate at much higher speeds

4. Cutting Applications:

  • Diamond Wire Saw (SGO20):
    • This type of saw is suited for a broader range of cutting tasks, including cutting larger blocks of materials or complex workpieces. It can handle both internal and external contours, as well as sectioning.
  • Endless Diamond Wire Saw:
    • Due to its continuous wire motion and higher speeds, this saw excels in precision cutting, especially for materials like silicon, graphite, sapphire, and optical glass. It is ideal for applications requiring high surface quality and minimal wire marks.
    • It can do both internal and external contours, as well as sectioning.but for the endless cutting wire’s diameter is normally bigger than spooled diamond wire.

5. Wire Maintenance:

  • Diamond Wire Saw (SGO 20):
    • Wire replacement is relatively frequent as the wire wears down or breaks due to repeated back-and-forth motion.
    • Re-spooling can take more time, especially if the wire is used extensively.
  • Endless Diamond Wire Saw:
    • The looped wire is more durable since there is no reversal of the motion, reducing the wear and need for frequent replacements.
    • Less downtime for wire replacement or adjustments due to its continuous loop design,there is not need to re-spooling, put a new cutting wire on normally take a few seconds.

In summary, while both machines use diamond-coated wire for cutting, the endless diamond wire saw offers faster, smoother, and more efficient cutting with easy operation, making it particularly suitable for high-precision applications. The Open-end type diamond wire saw (SGO 20), on the other hand, provides more versatility in terms of the wire length, application range, and cutting styles, making it useful for a wider variety of tasks.

Customer Testimonials

Industry: Ceramic Industry
We used the SGO20 CNC diamond wire cutting machine to cut an internal cross-shaped contour inside a 444 cm block of aluminum oxide (Al₂O₃). The machine performed exceptionally well in maintaining high precision during the cutting process, particularly when threading the diamond wire through the internal hole to execute the cross-cut.
The cutting speed was efficient, and the surface finish of the internal contour was smooth, with minimal roughness. The machine’s ability to handle this intricate internal shape without causing any chipping or cracking of the brittle material was impressive.
