You want compact, flexible equipment.
A single disc handles flat backs, specimen faces, free-form shapes, and cabochons. You trade a smaller footprint and lower listed entry price for changing discs between grit stages.

Flat lap or cabbing machine?
Both can shape and polish stone. The important difference is how you move through the work: changing discs on one lap, or moving a stone across a row of installed wheels.
Quick answer
Choose around the workflow you want.
Cabochons are the main job.
Multiple wheels stay installed in sequence, so you can move from shaping to polishing without stopping to exchange the main abrasive surface at every stage.
Compare cabbing machines →You want a disc system at an angle.
A slant cabber is still a flat-lap machine. The angled face improves visibility and supports seated work while preserving the compact, interchangeable-disc approach.

The differences that change daily use.
| Decision | Flat or slant lap | Multi-wheel cabbing machine |
|---|---|---|
| Working surface | One horizontal or angled disc at a time | Several wheels installed in a grit sequence |
| Moving through grits | Change discs or backing plates between stages | Move the stone from wheel to wheel |
| Natural strength | Flat backs, specimen faces, free-form shapes, and occasional cabochons | Repeated shaping and polishing of rounded cabochons |

Before you buy
Four questions settle most of the decision.
- What will you make most often?Rounded cabochons, flat specimens, free-form shapes, or a mix?
- Will disc changes interrupt you?Occasional work tolerates them; repeated production makes the wheel sequence more valuable.
- Where will the machine live?Compare the complete footprint, weight, water handling, and storage—not only wheel diameter.
- What is the usable setup cost?Include abrasives, polishing supplies, coolant hardware, safety gear, and any cutting equipment you still need.
