SGI 20
SGI 20 is an contour cutting machine used for cutting and processing silicon, glass, sapphire, quartz, jade, and other materials into irregular shapes using diamond wire.
This contour cutting machine uses a gantry structure, and the cutting wire cuts from top to bottom. It is very convenient to load the workpiece. It only needs to be glued to the loading table, and the cut part will not fall after the cutting wire cuts through the material, so there is no need for workers to take care of it. It only needs to be processed after the equipment program is completed or the next day.
Complex shapes are drawn with CAD software, and the software includes CAM graphic editing (straight lines, arcs, oblique lines) for importing. Through a high-speed rotating diamond wire, this equipment achieves a processing technique for cutting workpieces. It is a new type of equipment with reliable functionality, high cutting efficiency, and high processing accuracy.

The cutting tool used by the equipment is also the latest ring-shaped diamond wire. By forming the diamond wire into a closed loop, the one-way movement of the cutting wire is achieved, which greatly improves the linear speed and the smoothness of the cutting surface. It is a cutting machine with good precision .
Diamond Wire Loop has 3 different types: Full coating ,Segment Coating and Thread Coating. Each has it’s advanagtes.

The Difference between SG I20 diamond wire saw cut machine and other types
The equipment capable of cutting shapes typically includes electrical discharge machining (EDM), laser cutting, water jet cutting, diamond wire cutting, and engraving. Electrical discharge machining requires materials to be conductive for cutting, while laser and water jet cutting are limited by material thickness—if it’s too thick, penetration may be insufficient. Engraving also has requirements regarding material thickness. Diamond wire cutting, however, has no restrictions on the type of material being cut.
Diamond wire cutting and electrical discharge machining (EDM) are often compared because they both fall under the category of wire cutting. Here’s a comparison between these two cutting methods
Comparison of Diamond Wire Cutting and EDM Wire Cutting
| Characteristics | Diamond Wire Cutting | EDM Wire Cutting |
|---|---|---|
| Material Compatibility | Suitable for various materials | Limited to conductive materials |
| Cutting Speed | Fast | Relatively slow |
| Material Thickness | Not limited | Limited by material thickness |
| Precision | High | High |
| Heat Generation | Low | None |
| Wire Breakage | Susceptible | Minimal |
| Operating Costs | Moderate to high | Moderate to high |
| Maintenance | Requires frequent wire replacement | Potential for electrode wear |
| Application Flexibility | Suitable for complex shapes | Suitable for complex shapes |
| Waste Material | Minimal | Minimal |

What is the maximum thickness the machine can handle for cutting?
What is the difference between this wire saw and ID SAW?
Their cutting tools differ; one uses a diamond wire and the other a blade, making one a flexible cutting method and the other a rigid cutting approach. Furthermore, inner-circle slicers limit the workpiece size to be smaller than the blade’s inner diameter, whereas SHINE OptiGantry Wire Saw does not have this restriction.
How does the machine minimize material waste during cutting?
What is the expected lifespan of the diamond wire, and is it user-replaceable?
Does the machine require a specialized environment or setup conditions?
What kind of technical support and warranty do you offer with the purchase of this equipment?
What is an endless diamond wire saw?
Unlike traditional wire saws that use long reciprocating wires, the endless wire saw operates smoothly without reversing direction, resulting in higher stability, faster cutting speed, and superior surface quality.
How is it different from a traditional wire saw?
The Vimfun endless wire saw eliminates this by using a short closed loop that moves continuously in one direction.
This improves cutting efficiency, extends wire life, and produces a cleaner, more precise cut.
What materials can be cut using an endless diamond wire saw?
It is widely used in semiconductor, solar, optical, and advanced materials processing industries.
