Diamond Wire Loop

Diamond wire loop is a diamond wire top and tail conected into a closed-loop, its surface is coated with diamond particles, and it is a circle of sertain length,normally within 10 m. It can be used to cut various materials with a hardness lower than diamond.

Electroplated Diamond Wire loop saw, as a revolutionary new cutting tool, is gaining widespread attention in the industrial field.
Its uniqueness lies in the use of high-strength diamond particles, which are evenly distributed on the surface of a flexible steel wire, enabling this tool to achieve high precision and efficiency in cutting processes.
The loop design means that the diamond wire do one-direction cutting instead of traditional repetation cutting.And the thin wire diameter means it can cut in multiple directions, greatly enhancing its applicability in complex and delicate cutting tasks.
Additionally, this loop structure also makes the diamond wire more stable during use, reducing the risk of breakage and thereby extending the tool’s lifespan.

The difference between different types of Diamond Wire Loop

Full-Coated Electroplated Diamond Wire Loop:
- The cutting wire of full-coated wires is relatively thin, with the thinnest being 0.3 mm.
- These wires are particularly advantageous in cutting hard and brittle materials such as quartz, silicon rods, optical glass, and rare metals.
- These wires are particularly advantageous in cutting hard and brittle materials such as quartz, silicon rods, optical glass, and rare metals.
- The fully coated wire has a large number of diamond abrasives all over the surface of the cutting wire, so it has a strong cutting force. Therefore, it has obvious advantages when cutting materials with small chip removal and high hardness.
- Our fully coated wire not only has a high abrasive density, but also uses a mixture of raw diamonds and crushed diamonds, making the cutting wire both sharp and wear-resistant. Therefore, the service life is longer than others.
Segmented-Coated Electroplated Diamond Wire Loop:
- The thinnest segmented-coated wire is 0.8mm.
- The segmented coating creates a lot space on the surface of the cutting wire, which can accommodate a large amount of material debris during the cutting process. As the cutting wire moves, it carries and discharges the debris, significantly increasing its chip removal capacity.
- These wires excel in cutting materials like graphite and corrugated paper, which are not very hard but produce a lot of dust.
Thread- Coated Electroplated Diamond Wire Loop:

The thinnest thread-coated wire is 0.5 mm.
The threaded coating creates spiral gaps on the surface of the diamond wire, which can accommodate a large amount of material debris during the rotation of the cutting wire. As the cutting wire moves, it carries and discharges the debris, significantly increasing its chip removal capacity.
These wires excel in cutting materials like graphite and corrugated paper, which are not very hard but produce a lot of dust.

Additionally, full-coated Electroplated Diamond Wire Loop are widely used in materials processing where cutting fluid can be applied, whereas segmented-coated and thread- coated diamond wires are mainly used in dry cutting processes.

Customer Testimonials

Semiconductor : Graphite Manufacturing

We mainly process monocrystalline silicon and quartz glass, where cutting precision and surface quality are critical. After using this diamond wire, the cutting speed increased significantly, shortening the production cycle by about 30%. The cut surfaces are smooth and flat, with no need for additional polishing, which has greatly simplified the overall processing steps. The wire also shows excellent stability. During long periods of continuous operation, there were no incidents of breakage or deviation, and material loss was noticeably reduced. Overall, production efficiency, yield rate, and cost control have all improved significantly.

Frequently Asked Questions

What is a diamond wire loop?

A diamond wire loop is a closed-loop cutting wire coated with diamond abrasive grains.
Unlike traditional long reciprocating wires, it forms an endless ring, allowing continuous one-direction cutting with higher stability and precision.

How does a diamond wire loop work?

The wire loop runs continuously around guide pulleys at high speed (typically 60–80 m/s).
The diamond abrasives on the wire surface grind through the material, producing a fine, smooth, and chip-free surface.

What are the main advantages of a diamond wire loop?

No need for wire direction reversal
Higher cutting speed and efficiency
Lower vibration and noise
Longer lifespan and reduced kerf loss
More stable for hard and brittle materials

What wire diameters are available?

It is ideal for silicon, sapphire, ceramics, quartz, graphite, and composite materials.
Common industries include semiconductor, LED, optical glass, carbon materials, and precision component manufacturing.

How is the diamond abrasive bonded to the wire?

Vimfun diamond wire loop uses electroplated methods to ensure even diamond grain distribution.
This improves cutting consistency and prevents premature abrasive loss.

What determines the cutting quality of a diamond wire loop?

What determines the cutting quality of a diamond wire loop?

Can the diamond wire loop be reused or reconditioned?

No. Once the diamond layer wears out, the loop must be replaced.
Reconditioning is not feasible because the closed-loop structure prevents re-plating.

How to store diamond wire loops properly?

Keep loops in a dry, clean environment, away from moisture or direct sunlight.
Avoid bending or twisting, as deformation may affect rotation balance.

What determines the cutting quality of a diamond wire loop?

What determines the cutting quality of a diamond wire loop?

Can Vimfun diamond wire loops be customized?

Yes. We provide custom loop lengths, grit sizes, and bonding types based on material and equipment models (e.g., Vimfun SVI60, SVI80, or other brands).

How to identify wire wear or end of life for a diamond wire loop?

If cutting speed decreases or the surface shows roughness increase, the wire loop is near end-of-life.
Visible color fading or abrasive loss also indicates replacement is required.
