SG 20
SG20 is a compact CNC Glass Cutting Wire Saw，also called glass cutting Wire Saw. It uses an enfdless diamond wire as a cutting tool. It is very suitable for laboratories and small studios to cut various glass, ceramics, gemstones and other hard materials.
This CNC Glass Cutting Wire Saw uses a gantry structure, and the cutting line 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 line 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. The equipment of this structure also has larger models, and can also be upgraded to a special-shaped cutting program for complex contour cutting.

The cutting tool used by the equipment is also the latest ring-shaped diamond wire loop. 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 20 diamond wire saw machine and ID Slicer
Endless Diamond Wire Cutting Equipment and Inner Diameter Slicing Machines are both used for cutting hard and brittle materials like glass and magnet. but they differ significantly in their design, operation, and applications.
Description:
- Endless Diamond Wire Cutting Equipment uses a continuous loop of diamond-coated wire to cut through materials. It is known for its high precision and ability to cut large and thick materials efficiently.
- Inner Diameter (ID) Slicing Machine uses a circular blade with an inner diameter edge coated with diamond particles. It is typically used for slicing smaller, thinner materials with high precision.
Comparison Table:
| Feature | Endless Diamond Wire Cutting Equipment | Inner Diameter Slicing Machine |
|---|---|---|
| Cutting Mechanism | Continuous loop of diamond-coated wire | Circular blade with diamond-coated inner diameter edge |
| Material Thickness | Suitable for thick and large materials | Best for thin and small materials |
| Cutting Precision | High precision with smooth cuts | high precision with smooth cuts |
| Material Waste | Minimal material waste due to thin wire | Minimal material waste due to thin blade |
| Cutting Speed | High cutting speed | Moderate to high cutting speed |
| Operational Cost | Generally lower operational costs | Higher operational costs due to blade wear and replacement |
| Maintenance | Regular wire inspection and replacement | Frequent blade maintenance and replacement |
| Applications | Photovoltaic , semiconductor, Magenet, Optics | Photovoltaic , semiconductor, Magenet, Optics |
| Initial Investment | Moderate to high | High |
| Flexibility | More flexible, can handle various shapes and sizes | Less flexible, best for specific size ranges |
| Surface Quality | Produces smooth surface finishes | Produces smooth surface finishes |
| Production Volume | Suitable for high-volume production | Suitable for low-volume production |
Summary:
Endless Diamond Wire Cutting Equipment is ideal for applications requiring high efficiency and the ability to handle large, thick materials with minimal waste. It offers flexibility and lower operational costs, making it suitable for industries like optoelectronic and semiconductor manufacturing.
Inner Diameter Slicing Machines excel in precision cutting of thinner and smaller materials, producing extremely smooth surfaces. They are commonly used in semiconductor and optoelectronic industries but come with higher operational costs and maintenance requirements.
Both types of equipment have their unique advantages and are chosen based on specific cutting requirements and application needs.

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?
An endless diamond wire saw uses a closed-loop diamond wire, typically around 10 meters long, running continuously in one direction at a high linear speed (up to 80 m/s).
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?
Traditional wire saws use kilometers-long wires moving back and forth, which require direction changes and tension adjustments.
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?
The Vimfun endless diamond wire saw can cut hard and brittle materials such as silicon, sapphire, ceramics, graphite, glass, and carbon fiber composites.
It is widely used in semiconductor, solar, optical, and advanced materials processing industries.
What is the wire speed and tension of endless wire saw in operation?
The diamond wire runs at a linear speed of 60–80 m/s with tension between 150–250 N.
These parameters ensure high cutting efficiency and stable motion, producing consistent cutting surfaces across various materials.
What are the safety precautions during endless diamond wire saw operation?
Always check wire integrity before startup.
Vimfun machines include emergency stop functions and speed monitoring for safety assurance.
Does Vimfun Diamond Wire Saw offer customization or OEM service?
Engineering teams can adjust wire length, machine size, and automation level based on client requirements.
How does endless diamond wire cutting reduce costs?
Energy consumption is lower due to smooth motion and reduced vibration.
Overall, total cost per cut can decrease by 20–30% compared to traditional systems.
