One Wheel per Cardboard Box: Why Packing Matters for Cotton Buffing Wheels

Every buffing wheel we ship leaves in its own cardboard box, including the stocked 150 x 19 x 20 mm hexagon-bore size. The box is not decoration. It is the difference between a wheel that polishes an edge and a wheel that scratches it.

Layered cotton is an open, soft surface. Left on a workbench it collects metal swarf, sanding dust and grit from the floor, and those particles embed in the face rather than sitting on top of it. A contaminated wheel does not polish. It cuts fine scratches along the edge line, and on a dark or high-gloss banding those scratches are visible under a raking light long after the panel has left the line.

The problem is easy to misread. The operator sees a dull, scratched edge and blames the wheel grade or the glue, when the cause is a wheel that spent three weeks open on a bench.

• Keep the wheel in its box until it is mounted, and put the box back on a shelf, not on the bench
• Do not stack loose wheels face to face, because the cotton takes an impression and the face stops running flat
• Keep the box off damp concrete; cotton that has drawn moisture buffs unevenly and the effect does not wear off
• Write the size on the box, since a 150 mm wheel looks much like a 160 mm one once the label is gone

Wheels are made in Guangdong, China, and standard lead time is 5-8 work days. Packing is one wheel per cardboard box for both stocked and made-to-order sizes, so a mixed order arrives as a set of clearly labelled boxes rather than a carton of loose wheels.

If you keep spares on the shelf, order two or three of the size your line uses. A changeover then costs one machine stop, not one week of waiting for a part that was ordered after the old wheel was already worn through.
