Why is sapphire difficult to cut?
Sapphire combines high hardness with brittleness. Unstable cutting can create cracks, edge damage, and rough surfaces that increase downstream processing cost.
What does literature say about sapphire loop cutting?
A reported study used a looped diamond wire to cut a sapphire cylinder and examined how parameters influenced roughness. The result should be treated as experiment-specific.
What is the safest commercial approach for sapphire?
Use test cutting first. Confirm cut time, roughness, edge chipping, kerf, wire wear, and whether the surface meets the next processing step.
