Preguntas Frecuentes
How does diamond wire loop cutting work?
A metal wire — typically high-strength steel — is coated with diamond particles by electroplating or resin bonding and formed into a continuous loop. Driven at high speed, the embedded diamonds micro-grind the workpiece, slicing hard, brittle materials with a very narrow kerf and smooth surfaces.
Why is diamond wire loop cutting suited to magnetic materials?
Magnetic materials are hard, brittle and heat-sensitive. The wire loop cuts with distributed low force (no cracking), generates little heat (no demagnetization), and its fine diameter wastes very little of costly rare-earth stock — a combination grinding, laser and EDM cannot match.
Can diamond wire loops cut both permanent and soft magnetic materials?
sí. The same process handles permanent magnets such as NdFeB and SmCo, soft magnetics such as ferrites and silicon steel, and even magnetic thin films, with only parameter and wire-grit changes between materials.
What limits diamond wire loop cutting today?
Three things: wire wear over long runs (addressed by more wear-resistant coatings), heat build-up at aggressive parameters (managed with cooling and optimized settings), and the initial equipment cost, which falls as the technology scales and matures.
