Magnetic Finishing for Small Precision Metal Parts: Symptom, Cause, Check and Adjustment
This page reproduces the published troubleshooting table for magnetic finishing of small precision metal parts: the symptoms with their likely causes, what to check first and the adjustment to test. Checks and adjustments are the article own, reproduced verbatim. Small precision parts vary in material, geometry, magnetic response and tolerance, so confirm on a sample and with the supplier before production.

Symptom, likely cause, what to check and recommended adjustment
| symptom | likely cause | what to check | recommended adjustment |
|---|---|---|---|
| Surface finish is inconsistent across the batch | Uneven media distribution or part-on-part contact | Media-to-part ratio, machine loading, compound flow | Adjust ratio, reduce batch size, or add cushion media |
| Parts show unexpected scratches or surface marks | Contaminated media, wrong media shape, or overly aggressive cycle | Check media cleanliness, separation, and storage bins for mixed materials | Clean or replace media, test a gentler media shape or smaller size |
| Edges are rounded or functional details are lost | Over-processing or media too large for part features | Measure critical dimensions before and after test cycles | Shorten cycle time, use smaller media, reduce machine speed or amplitude |
| Surface residue or film is visible after drying | Dirty compound, poor water quality, or incomplete rinsing | Water quality, compound concentration, rinsing and drying sequence | Use clean water, refresh compound at proper intervals, improve drying process |
| Brightness varies significantly between parts | Mixed surface starting conditions or uneven processing | Incoming part surface, batch sorting, media distribution | Sort parts by starting condition, run separate batches for different surface states |

Frequently asked questions
Does this give me a recipe or a machine?
No. These are the published article own rows reproduced verbatim. They are a direction to confirm on a sample and with the supplier, not a validated production recipe or a machine recommendation.
Does this page quote prices or supplier details?
No. No price, machine model, cycle time or supplier evaluation appears anywhere on this page or in its download.
Does it diagnose my part?
No. A symptom lists a likely cause and a first check. The same visible mark can have more than one cause, and confirming it needs a controlled test on a sample.
Does it state cycle time, speed or temperature?
No. No cycle time, speed, amplitude, load ratio, concentration, temperature or removal result is stated or implied anywhere on this page or in its download.
Are the tables quoted exactly?
Yes. Every cell is taken from a single source table cell and verified against the captured page, including wording and punctuation.
