The situation
A Tier 2 aerospace shop finished parts by hand. One skilled operator could make a single part look excellent. Across a batch, the results drifted, and fatigue-critical parts need a uniform low-stress surface, not a good day and a bad day.
They were skeptical that a barrel could match a careful hand polish.
What we did
We ran their part in a stainless controlled-velocity machine with a figure-8 motion, the same unit that would do their production. Media and compound were matched to the geometry so energy reached the bores and slots, not just the flats.
The result
The finish came back even on every edge and bore, and it came back that way on every part.
- Every edge finished uniformly, no directional tool marks
- Isotropic surface suited to fatigue-critical parts
- Same result, every batch, with no reliance on one operator's best day
The before-and-after part decided it. They could hold the proof in their hand.
The takeaway
The question is never just "is it good." It is "is it good the ten-thousandth time." A centrifugal barrel removes the human variance and gives you the same isotropic finish on every part, every cycle.
