DA and Rotary Pads: Prevent Picking the Wrong System

A workshop using rotary, free-spinning orbital and gear-driven orbital tools needs more than a colour-coded pad shelf. Similar-looking pads can have different approved applications, and colours are not a universal compatibility standard.

Label the approved pairing

Record the manufacturer, pad identifier, size and approved machine movements from its documentation. Keep the appropriate backing-plate pairing with the record. Do not relabel a pad as universal simply because it attaches to more than one tool.

Organise storage by approved system, then by role such as cutting or refinement. Keep the role label separate from the compatibility label: a finishing pad’s intended abrasive role does not establish which machine it belongs on.

Build a picking check

Before fitting a pad, compare its identifier with the job’s selected machine and backing plate. Inspect the pad and attachment surfaces. If packaging has been discarded, use an authoritative stock record rather than identifying compatibility from foam colour or thickness.

Keep used pads traceable to their liquid and role. A correctly compatible pad can still be unsuitable for final refinement if it carries residue from an earlier cutting stage or has not been cleaned and dried appropriately.

Review errors without guessing

If the wrong pad is selected, stop and assess the equipment and surface before continuing. Record the exact components and whether any work occurred. Do not assume that a mismatch always causes visible damage, or that the absence of visible damage makes the pairing approved.

Use near-miss records to improve labels and storage. Place look-alike pads in clearly distinct locations rather than relying only on staff memory during a busy handover.

RUPES documents movement-specific pad families in its polishing-system guidance. The vibration diagnostic guide supports a check when equipment behaviour changes after fitting a pad.
