ECO Manual Polishing Machine: Published Parameters, Stages, Faults and Parts
This page reproduces the tables published for the ECO manual polishing machine: its technical parameters, the process stages with wheel and compound, the fault symptoms with probable causes and corrective actions, the spare parts with factory part numbers, and the mandatory maintenance schedule. Every figure is the article's own for its own machine, reproduced verbatim. A published speed, stage or part number is not a validated process for your part: confirm the recipe on a sample and with the supplier.

Fault symptom, probable cause and corrective action
| fault symptom | probable root causes | corrective action |
|---|---|---|
| Machine will not power ON | Main breaker tripped; E-Stop locked down; blown fuse. | Reset breaker; rotate E-Stop clockwise to release; check fuse. |
| Motor hums but will not spin | Phase loss on power line; VFD fault; arbor jam. | Verify incoming line voltages; check VFD code; clear arbor. |
| Excessive machine vibration | Unbalanced buffing wheel; loose M16 lock nut. | Dress or replace buffing wheel; tighten M16 nut to 45 N·m. |
| Weak suction airflow at hood | Filter bags caked; drawer unlatched; duct clog. | Pump shaker lever 10 times; clamp drawer tight; clear duct. |
| Workpiece burning (Acetate) | RPM too high; excessive pressure; dry buffing wheel. | Reduce speed to 2,000–2,400 RPM; use light touch; apply wax. |
| Swirl marks / haze on surface | Wheel contaminated with coarse compound/grit. | Rake wheel clean; use dedicated buffing wheel per compound. |
| Acoustic squeal / grinding noise | Dry spindle bearings; loose drive belt rubbing frame. | Grease bearings with Mobil Polyrex EM; adjust belt tension. |

Frequently asked questions
Are these our machine specifications?
No. Every figure is the published article's own for its own machine, reproduced verbatim. It is not a specification for any other machine and not a validated process for your part.
Does it tell me what cycle or speed to use?
No cycle time, speed, amplitude, load ratio, concentration, temperature or removal result is implied beyond the article's own published values, and those are its starting points to test on a sample with the supplier.
Are the fault rows a diagnosis?
No. They give probable causes and corrective actions to check, not a diagnosis and not a warranty repair instruction.
Are the tables quoted exactly?
Yes. Every cell is taken from a single source table cell and verified against the captured page, including units, ranges and punctuation.
Can I use this for a different machine model?
The values describe the article's machine. Media, compound, speed and cycle time must be re-established for your own part, machine and acceptance criteria.
