Build a polishing path around the starting surface, contact tool, compound, equipment, and acceptance criteria.
Polishing compounds, liquids, cloth wheels, sisal wheels, nonwoven wheels, and pads are system components rather than interchangeable standalone products. A compound cannot be selected responsibly without understanding the surface delivered by the previous step and the way the tool contacts the part.
Five decisions shape the process
| Decision | Why it matters | Information to provide |
|---|---|---|
| Starting surface | Deep marks cannot be corrected reliably by a final-finish step alone | Previous abrasive, visible defects, and photographs |
| Substrate | Material response, loading, and heat sensitivity differ | Material grade or best available description |
| Contact tool | Wheel or pad construction changes pressure distribution and cut | Cloth, sisal, nonwoven, pad, diameter, and density where known |
| Equipment | Speed, motion, access, and workholding define the usable process window | Manual or automated process, machine type, and speed where known |
| Acceptance | “Mirror” or “bright” can mean different visual and measurable outcomes | Approved sample, visual standard, or agreed measurement method |
Build the sequence from preparation to finish
- Remove defects and establish a consistent starting texture.
- Select the contact wheel or pad for geometry, access, and required cutting action.
- Match the polishing material to that contact tool and substrate.
- Evaluate the sequence on a representative part under controlled conditions.
- Record the approved combination before transferring it to production or automation.
Polishing materials and contact tools must be matched to the application. GUOWIN’s current catalogue is organized into nine product series. Trials on the actual part are the reliable way to confirm appearance and process stability.
What a useful request contains
Send the substrate, current abrasive marks, part geometry, available equipment, target appearance, expected cycle, and representative images. For automation projects, also include workholding, accessible surfaces, planned volume, and acceptance criteria.
