Frequently Asked Questions (FAQ)

1. Why is 0.45 – 0.50 g/cm³ the optimal density range for industrial wool felt wheels?

A density of 0.45 – 0.50 g/cm³ provides the ideal engineering balance for metal and optical finishing. It is firm enough to maintain geometric flatness and prevent edge deformation during high-pressure buffing, while preserving the natural elasticity needed to conform to curved contours and securely lock abrasive compounds without rapid glazing.

2. How do Rolking wool felt wheels achieve Ra < 0.015 µm surface roughness in precision lapping?

Our 100% natural wool felt wheels undergo multi-directional hydraulic pressing and thermal carbonization. This creates an extremely dense, uniform fiber structure that evenly embeds 1µm diamond lapping particles without allowing agglomerations. The resilient matrix maintains exact planar contact across workpiece surfaces without gouging, achieving certified Ra < 0.015 µm roughness.

3. Are these wool felt discs suitable for Cleanroom Class 100 electronics manufacturing?

Yes. For 3C electronics and optical cleanrooms, we provide specially washed and de-dusted wool felt discs. The carbonization process removes all vegetable matter and loose fibers, minimizing particulate generation and static accumulation when polishing titanium smartphone frames and optical camera lens rings.

4. What is the recommended technique for polishing large stainless steel pressure vessel welds?

For sanitary and pharmaceutical tanks, grind the weld bead flush with fine abrasive discs (P400–P800) first. Then mount our 0.45–0.50 g/cm³ wool felt wheel with Green Chromium Oxide compound on an angle polisher at 1,800–2,500 RPM. The natural wool fibers dissipate frictional heat rapidly, preventing localized discoloration and grain boundary oxidation.

5. Do you support custom shank sizes, arbor reducers, and OEM private branding?

Yes. Rolking Felt is a comprehensive OEM/ODM manufacturer. We can produce custom arbor holes (from 3mm shanks to 50mm large bores), customized outer diameters (20mm–350mm), hook & loop Velcro backings, and branded export packaging for global industrial distributors.
