Soft yellow cotton wheels with controllable cloth density.
Ask about sample supply, volume orders and custom specifications.
Request a quoteThese yellow WanHu buffing wheels use soft cotton cloth with a density that can be adjusted from open to tightly sewn. The cloth face holds polishing compound and provides compliant contact with the workpiece.
Use for controlled polishing and final brightening where a soft wheel and polishing compound are appropriate. Confirm wheel size, bore and machine speed before ordering.

A bigger wheel must run slower. The limit is set by peripheral speed (how fast the rim travels), not by a fixed RPM number — so the safe RPM drops as the diameter grows.
| Wheel diameter | Spec code | Max. safe speed | Peripheral speed at that limit |
|---|---|---|---|
| Ø 100 mm4" | 4 × 50 | ≤ 6,000 RPMMaker rating on small wheels — the arbor and guard set the real ceiling | 31.4 m/s |
| Ø 150 mm6" | 6 × 50 | ≤ 3,000 RPMMost common size — many makers rate it at 2,800 RPM | 23.6 m/s |
| Ø 200 mm8" | 8 × 50 | ≤ 2,200 RPM | 23.0 m/s |
| Ø 250 mm10" | 10 × 50 | ≤ 1,800 RPM | 23.6 m/s |
| Ø 300 mm12" | 12 × 50 | ≤ 1,400 RPM | 22.0 m/s |
Spec code format: diameter (inch) × ply count — 4 × 50, 5 × 50, 6 × 50, 7 × 50, 8 × 50, where 50 ply means 50 cotton layers. Finished thickness is 12 mm across the whole range.
Peripheral speed = π × diameter (m) × RPM ÷ 60
