Loop Type Diamond Wire- 0.3 mm
This is a Loop type Fine Wire Saw, its surface is coated with diamond particles, and it is a circle of custom length. It can be used to cut various materials with a hardness lower than diamond.
The Loop type Fine Wire 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 Tungsten wire.
The diameter 0.3mm enabling this tool to achieve high precision and efficiency in cutting processes.
The circular 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 circular structure also makes the diamond wire more stable during use, reducing the risk of breakage and thereby extending the tool’s lifespan.

Frequently Asked Questions
What is a loop type diamond wire?
How does loop type diamond wire differ from traditional diamond wire?
Traditional diamond wires are long (hundreds or thousands of meters) and require direction reversal during cutting.
Loop type diamond wire operates in a short closed loop (usually 5–10 meters), eliminating direction switching, which results in higher efficiency, reduced vibration, and improved cutting precision
What materials can be cut using loop type diamond wire?
Loop type diamond wire is suitable for hard and brittle materials, including:
Silicon and sapphire
Ceramics and quartz
Graphite and carbon composites
Optical glass and semiconductor materials
What are the main advantages of loop type diamond wire?
Continuous cutting with no reciprocation losses
High surface quality and minimal chipping
Low kerf loss due to thin wire (as small as 0.3 mm)
Long lifespan with consistent cutting performance
Reduced maintenance compared to long-wire systems
What is the typical length and speed of a loop type diamond wire?
Cutting speed can reach up to 80 m/s, ensuring clean and precise cuts even on high-hardness materials.
How long can a loop type diamond wire last?
Tool life depends on material hardness, feed rate, wire tension, and coolant quality.
Under standard conditions, one loop can last dozens to hundreds of cuts, significantly longer than traditional diamond wires.
How is the diamond coating distributed on the loop wire?
Diamond abrasives are uniformly electroplated on the wire surface.
Uniform coating ensures even wear, stable cutting speed, and improved surface finish.
What are the maintenance tips for loop type diamond wire?
Avoid wire twisting or bending during installation
Keep cutting area clean and well-lubricated
Use proper wire tension (typically 150–250 N)
Regularly check pulleys for wear or debris buildup
How to select the right loop type diamond wire for your application?
Selection depends on material hardness, desired surface roughness, and cutting speed.
Consult your equipment supplier for suitable wire grit size, bond type, and diameter.
