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.

What is a loop type diamond wire?
A loop type diamond wire is a closed-loop cutting wire coated with diamond abrasives. Unlike long reciprocating wire saws, it forms an endless loop that runs continuously in one direction, providing stable cutting speed and smoother surface quality.

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

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

  • 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

The loop length is typically 2–10 meters, depending on machine design.
Cutting speed can reach up to 80 m/s, ensuring clean and precise cuts even on high-hardness materials.

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.

Diamond abrasives are uniformly electroplated on the wire surface.
Uniform coating ensures even wear, stable cutting speed, and improved surface finish.

  • 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

Selection depends on material hardness, desired surface roughness, and cutting speed.
Consult your equipment supplier for suitable wire grit size, bond type, and diameter.
For precision work, Vimfun provides customized diamond wire loops with optimized specifications.
