Structure
The usual structure includes a steel wire substrate, an electroplated metal bond layer, and exposed diamond abrasive. The coating must hold the abrasive firmly while leaving enough grit protrusion for cutting.
Chinese research papers frequently discuss substrate material, welding method, manufacturing sequence, and cutting tests together because a loop wire failure may come from any of these elements.
Practical quality factors
Uniform abrasive distribution helps reduce unstable cutting marks. Weak abrasive retention shortens life. Excessive coating can reduce sharpness, while insufficient coating can lead to premature diamond loss.
For endless wire, the joint area must be considered separately because it experiences repeated bending over guide wheels and must pass smoothly through the cutting path.
