The Inovatec VA Series centrifugal disc finisher is a high-energy mass finishing machine designed for fast deburring, edge radiusing, and polishing of small to medium parts. Compared with vibratory bowls, disc finishers deliver higher energy and shorter cycle times while keeping parts protected in a controlled media flow. VA9 / VA20 / VA38 models support wet finishing with compound dosing and dry polishing with organic media for jewelry, watch parts, precision hardware, and 3D-printed parts.

Centrifugal Disc Finisher VA series Gyrate polishing machine is a high energy mass finishing machine. It can accomplish quite a lot finishing job in a short time. In addition, VA series machines significantly reduce material handling and manual involvement in metal finishing. Supports ultra-thin parts down to 0.05 mm thickness (with correct media selection).
VA9, VA20, and VA38 series gyrate polishing machine adopt patent small gap (about 0.05-0.1mm) design. Therefore we can polish very thin parts like earring and pendants. This user-friendly feature made it possible to polish complicated and thin workpiece.
Recommended Media & Process Recipes
Note: Cycle time depends on part geometry, burr size, and finish target. Run a small trial batch to confirm the best recipe.
| Step | Machine & mode | Goal | Media | Compound | Time | Notes |
|---|---|---|---|---|---|---|
| 1 | VA20 – Wet finishing | Deburring / edge rounding | Ceramic media | LC-13 | 1 hour | Use when parts have visible burrs or sharp edges. Rinse after step. |
| 2 | VA20 – Wet finishing | Pre-polish / surface smoothing | Plastic media 2000# | LC-13 | 2 hours | Improves surface clarity before dry polish. Rinse and dry parts before step 3. |
| 3 | VA20 – Dry finishing | Mirror shine / final polish | Walnut shell | HM-P polishing paste | 2 hours | For final gloss. Ensure parts are fully dry to keep media clean and consistent. |

A high-energy mass finishing machine that uses a spinning disc to polish and deburr small to medium parts by forcing media and workpieces against a fixed PU wall.
| Machine type | Best for | Typical part thickness | Main advantage | Watch-outs / limits | Recommended when |
|---|---|---|---|---|---|
| CF Series “Zero-Gap” model | Ultra-thin parts where any gap can trap/wedge parts | Ultra-thin / foil-like parts | Zero-gap structure prevents part wedging, best protection for delicate pieces | Specialized use-case; process recipe must be dialed in | You finish very thin parts and must avoid any jamming risk |
| VA Series Centrifugal Disc (small-gap / thin parts) | Thin parts needing high-energy finishing with controlled flow | Down to 0.05 mm | Fast cycle + controlled media flow, strong edge radiusing / smoothing with reduced part-to-part damage | Not ideal for very large/heavy parts; choose media size carefully | You need high-speed finishing for thin parts (≥0.05 mm) with consistent results |
| CD Series – Manual Discharge | General-purpose high-energy disc finishing (budget-friendly) | Thin to medium parts (depends on media/recipe) | Fast deburring/polishing with simpler structure and lower cost | More labor (manual unload/separation) | You want a cost-effective disc finisher for batch production |
| CD Series – Automatic Unloading | Production finishing with reduced labor | Thin to medium parts (depends on recipe) | Automatic discharge = lower labor + higher throughput + repeatability | Higher upfront cost; requires stable, repeatable process | You run daily/continuous batches and want labor savings |
Both. Supports dry polishing with walnut shell and wet finishing using water + compound.
