Why do glass and ceramics chip during cutting?
They are brittle. If cutting force fluctuates or the workpiece is poorly supported, cracks can propagate at the edge.
What helps reduce chipping?
Suitable feed rate, stable tension, fine abrasive selection, rigid fixturing, good coolant flow, and controlled entry/exit conditions can reduce chipping.
Should glass cutting be tested before buying equipment?
Yes. Test cutting gives practical evidence for edge quality, kerf, surface finish, and fixture requirements.
