High-purity synthetic diamond compounds for precision mold grinding, pre-polishing, and mirror surface finishing.
Refer to the technical selection table below to determine the precise micron grade and mesh equivalent for your specific mold polishing sequence.
| Grade | Micron (μm) | Mesh Equivalent | Stage | Primary Purpose |
|---|---|---|---|---|
| W40 - W14 | 10 - 40 μm | 320# - 800# | Coarse Grinding | Remove EDM layer, heavy machining marks, weld seams. |
| W10 - W5 | 3.5 - 10 μm | 1000# - 2000# | Fine Polishing | Eliminate grinding scratches, prepare for mirror finish. |
| W3.5 | 2.5 - 3.5 μm | 3000# | Pre-Mirror Polish | Standard pre-mirror finishing for injection molds. |
| W1.0 - W0.5 | 0.1 - 1.0 μm | 8000# - 10000# | Super Mirror | Final high-gloss scratch-free optical mirror polish. |
Q: What is the difference between oil-soluble and water-soluble diamond paste?
A: Oil-soluble paste provides superior lubrication and thermal stability during heavy grinding on hardened tool steels. Water-soluble paste is extremely easy to clean off with water, preventing oil residue build-up in deep mold cavities and narrow slots.
Q: How do I choose the correct micron grade for mold mirror polishing?
A: For standard mold restoration, follow a step-by-step polishing sequence: start with W14/W10 to remove stone scratches, transition to W3.5 for pre-mirror preparation, and finalize with W1.0 or W0.5 for an optical scratch-free mirror finish.
Q: How can I prevent cross-contamination during polishing?
A: Thoroughly clean the mold surface and change polishing laps/felt bobs before moving to a finer micron grade. Even a single coarse diamond particle can cause deep scratches on a fine mirror surface.
