Cutting Alumina Ceramics: Diamond Wire Loop Guide
Key Takeaways Alumina (알₂O₃) is hard, wear-resistant and brittle; the defect that matters is chipping at the entry and exit of the cut. Diamond wire cuts by distributed grinding rather than concentrated shearing, which keeps edges intact instead of fracturing them. Green (unsintered) bodies and fully sintered alumina need different wire grit and feed settings — treating them the same is a common cause of breakage. Four variables decide the result: wire grit and bond strength, coolant filtration, tension control, and feed rate. 소개: Beyond...
