Polishing Sequence
All-Diamond Dry Process — 30 · 15 · 3 · 0.5µm
01
Coarse Grind — 30µm

LAM PLAN Diamond HC 30µm on Ø30mm disc holder. Vacuum ON for precious metal swarf capture. Removes macro irregularities and establishes bore geometry.

05D 30A0 2005 — Green
02
Fine Grind — 15µm

LAM PLAN Diamond HC 15µm on Ø30mm disc. Refines scratch pattern from T1. Each step is 2–5× finer — the standard metallographic stepping rule for consistent material removal.

05D 15A0 2005 — Brown
03
Pre-Polish — 3µm

LAM PLAN Diamond HC 3µm on Ø18mm disc. Smaller disc accesses corner radii and base zones. Achieves Ra ~20nm pre-polish surface.

05D 03A0 2005 — Pink
04
Final Polish — 0.25µm

LAM PLAN Diamond HC 0.5µm on Ø18mm disc. Surface finish target Ra <0.25µm. Ra <5nm on PtAu alloy. Dimple exclusion zone maintained throughout.

05D 95A0 2005 — Grey · Ra <0.25µm target
Applications
Built For
◈
Platinum Group Metal Recovery

Dry process enables direct swarf capture from PtAu, PtRh, and pure Pt crucibles. HEPA filter collection — no precious metal lost to wet waste.

⊕
XRF Fusion Crucibles

Claisse BiS and equivalent PtAu crucibles polished to mirror finish without touching the base dimple. Extends crucible service life significantly.

◇
Precious Metal Refining

Moulds and crucibles used in gold, silver, and platinum refining operations. Consistent bore finish reduces contamination between pours.

⊙
Catalyst Preparation

Laboratory crucibles used in catalyst synthesis where internal surface condition affects reaction yield and product purity.

◉
Research & Development

University and industrial R&D labs requiring consistent, reproducible surface finish on small batch labware without manual polishing variability.

⊞
High Precision Surface Finishing

Any axis-symmetric bore requiring Ra <10nm finish in a lights-out automated environment. Custom recipes per geometry and material.
