CHALLENGES

SOLUTIONS

⚠️

Ultra-thin casings warp under high-pressure grinding

✓

SC Series P80–P5000 with flexible sponge backing protects workpieces

⚠️

Inconsistent Ra finish quality across high-volume production runs

✓

5-stage color-coded polishing system ensures repeatable Ra 0.8μm

⚠️

Long cycle times reducing throughput and increasing unit cost

✓

MSD600 automation delivers 3–5× throughput with ±0.01mm precision

⚠️

Scratch-free polishing of glass-to-metal interfaces is difficult

✓

Closed-loop process control with MSD600 eliminates manual variation

⚠️

UV/fingerprint degradation on cosmetic surfaces in daily use

✓

UV protection functional inks — 2000h resistance, 5B adhesion rating

Surface Finishing Process

Standardized Surface Finishing Roadmap

From stock removal to mirror finishing — A color-coded, repeatable process for high-volume 3C production.

P80

Stage 1: Initial Stock Removal

Burr removal & gate trace elimination — re-establishing the reference surface

SC Series

P220

Stage 2: Surface Equalization

Flattening and uniform material reduction — preparing surface for fine refinement

SC Series

P800

Stage 3: Fine Refinement

Sanding scratch elimination — approaching target Ra specification

SC Series

P3000

Stage 4: Pre-polishing Preparation

Final fine sanding stage — ready for optical polishing sequence

SC Series
