Typical Issues

· Mobile phone back panels and screen glass require a surface roughness of Ra ≤ 0.05 µm-a standard that cannot be consistently met through conventional grinding methods.

· Precision components demand dimensional tolerances of ±0.01 mm; consequently, the uniformity of abrasive grain size directly impacts manufacturing yield.

· Given the extremely high scrap costs associated with processing high-value materials (such as titanium alloys and ceramics), there is absolutely zero tolerance for any unreliability in the grinding tools used.

 

Recommended Solutions

· Ra Reduction Phase: Trizact Foam Discs(Progressive Sequence)

· Mirror Pre-polishing: Purple Ceramic Abrasive Film / Flexible Film - P2000–P5000

· Optical-Grade Mirror Finish: Trizact Film Sheets

· Flexible Polishing: Foam Abrasive Discs (Soft Backing) used in conjunction with a polishing machine
