Deburring · in plain shop language

Your machinists cut parts. We finish them.

Every part that comes off the mill, lathe, saw, or press has burrs, sharp edges, tool marks, or flash. Somebody has to take them off before the part gets anodized, coated, welded, assembled, or shipped. That somebody shouldn't be your $40/hr machinist standing at a bench with a file. Round and rectangular tube ends, weld-prep included — and because the Whisper Shake 5's interior is 33in long, tube and rail sections up to ~30in run whole, no cutting.

Burrs
Raised metal around holes, threads, and machined edges.
Sharp edges
Broken uniformly so parts are safe to handle and assemble.
Tool marks
Chatter, feed lines, and cutter witness marks knocked down to a uniform surface.
Flash & parting lines
Cast, molded, and stamped parts cleaned up cosmetically.

The process

Vibratory mass finishing, dialed to your part.

Parts and abrasive media ride the bowl together. Media does the work — millions of tiny cutting contacts per hour, uniformly, on every surface a machinist can't reach. We spec the media to your part and finish goal:

The line: a 5 ft³ Oceanic Innovations Whisper Shake 5 vibratory system (33in × 14.5in × 16in interior) — media matched to your part.

  • Ceramic — aggressive cut
    For heavy burrs on steel and stainless. Fast stock removal, uniform edge break.
  • Plastic — pre-anodize aluminum
    Gentle on soft alloys. Leaves a uniform matte surface that takes anodize evenly with no witness marks.
  • Steel — burnishing
    For a bright, work-hardened finish on brass, steel, and stainless. No stock removal — just shine.
Cosmetic parts
Fixtured and compartmentalized runs — no part-on-part impingement.

For visible surfaces where part-to-part contact would leave marks, we run in compartments or on fixtures. Your show-face stays show-face.

Try it, then decide
Send 20–50 parts. First sample lot is free.
We dial in media, cycle time, and finish on your part before you commit to a run.

I take a limited number of standing contracts on purpose. Once you're on the calendar it doesn't move — pickup Tuesday, finished parts back Thursday is the standard cadence.
Aluminum, steel, stainless, brass, and copper are the bread and butter. Titanium and nickel alloys on request — I'll spec the right media for your part.
Yes. Send the print or your target Ra, and I'll dial in media and cycle time on the sample lot. The process gets documented so every run repeats.
