SVO 20

The reciprocating wire cutting equipment operates using a diamond-coated wire that moves in a back-and-forth (reciprocating) motion to cut through the material. Here’s a simplified breakdown of its mechanism:

1. Workpiece Placement: The material to be cut is securely fixed on the worktable, which can move forward and backward to adjust the cutting position.

2. Wire Movement: The diamond-coated wire, which is stretched between two spools, moves in a reciprocating motion (back and forth). This motion allows the wire to engage with the material and cut through it.

3. Cutting Process: The wire, driven by a motor, moves at a controlled speed. As it moves across the material, the diamond abrasives on the wire gradually wear down the material, making precise cuts. The wire is guided by precision rollers to maintain the cutting path.

4. Tension and Speed Control: The tension of the wire and the speed of the reciprocating motion are controlled to match the material’s hardness, ensuring smooth cuts without damaging the workpiece.

5. Cooling System: A cooling liquid is often circulated around the cutting area to remove heat and debris generated during cutting, which helps maintain cutting efficiency and prolong the wire’s lifespan.

This mechanism enables the equipment to handle complex shapes and brittle materials with high accuracy and minimal material wastage.

Functions of SVO 20 Internal Contour Cutting Machine：

1. Sectioning and Slicing: The machine can be used to cut through workpieces entirely or to create precise slices from the material.
2. External Contour Cutting: It is capable of cutting the external contours of the workpiece, ensuring precision in defining the outer shape.
3. Internal Contour Cutting: By threading the cutting wire through an internal hole in the workpiece, the machine can cut internal contours, enabling intricate internal shape designs.

Same structure we have bigger machine size 

The same equipment structure is also available in larger models to accommodate the cutting of larger-sized materials, such as the SV O30 and SVO40. These models are specifically designed to meet the demands of cutting larger workpieces while maintaining the same high-precision cutting capabilities and efficient operation as the standard models.

The Difference of

Open-loop type Diamond Wire Saw And Endless Diamond Wire Saw

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

1. Wire Configuration:

• Diamond Wire Saw (SVO20):
  • 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 (SVO20):
  • 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 (SVO 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 (SVO20):
  • 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 (SVO 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 (SVO 20), on the other hand, provides more versatility
