Wood walnut shell tumbling defect check query

Choose dents, uneven finish, remaining dust, lodged media or little visible change. The source separates an observation from the first check and a possible adjustment. Bruised edges call for a review of falling action and fragile geometry. Uneven appearance retains the incoming sanding and blocked-flow questions. Dust and lodging have different separation checks. Keep several observations as separate rows so a longer cycle does not hide a handling or preparation problem.

Locate the first change before extending the cycle

Possible adjustments must be tested on representative wood parts. Keep every selected requirement with the part and the actual trial record. Selecting a row does not show that its acceptance condition has been met.

Inspect separation and upstream condition

Save an incoming reference and inspect representative parts after a short agreed trial, after separation and after cleaning. Record where the new mark or residue appears. Verify the smallest openings against the media grade and its worn condition. If deep machining defects remain, review upstream correction rather than treating walnut shell as a universal cutting process. The proposed changes are trial questions, with no numeric load, speed or duration.

Reviewed source reference

Dents or bruised edges

What to check first: Part concentration, falling action, fragile geometry

Possible adjustment to test: Increase cushioning, reduce part load, shorten the trial, or change equipment

Uneven finish

What to check first: Incoming sanding, blocked flow, mixed part sizes

Possible adjustment to test: Standardize incoming parts and restore consistent circulation

Dust or residue remains

What to check first: Media condition, excessive charge, separation method

Possible adjustment to test: Refresh media, reduce charge, and improve extraction or post-cleaning

Media lodged in holes

What to check first: Particle size versus smallest opening

Possible adjustment to test: Change grade or redesign the separation and inspection step

Little visible change

What to check first: Defect depth, media contact, movement, target definition

Possible adjustment to test: Correct the upstream defect or test a more suitable process
