Vibratory Bowl Finishing Machines — High-Throughput Mass Finishing
Industrial mass finishing machines built for small to medium batch processing. Achieve consistent deburring and polishing results with compact footprints and integrated parts separation. Trusted by metalworking, automotive, firearms, and medical device manufacturing facilities.
What Is a Vibratory Bowl Machine?
A vibratory bowl machine is an industrial mass finishing system utilizing a circular, toroidal processing chamber. It operates by generating a high-frequency vibration that causes the finishing media and parts to move in a continuous, corkscrew-like rolling action. This mechanical process ensures every surface of the part receives consistent, uniform contact with the abrasive media.
These machines excel at processing small to medium-sized parts in high-volume batches. They are the industry standard for deburring, polishing, descaling, and surface conditioning. The circular toroidal design naturally promotes high throughput while maintaining a compact footprint on the factory floor, delivering highly consistent batch finishing results cycle after cycle.

Choosing Between the VB and SB Bowl Series
VB Series (VB 1V, VB 3.5VT)
- Standard vibratory bowl design
- Best for general deburring, polishing, descaling
- Discharge door for media and part removal
- Available in 1 and 3.5 cubic foot capacities
- Simpler operation, lower entry point
SB Series (SB-2V, SB-4V)
- Includes integrated parts unload system with large removable screen
- Drop-in separation (SB-2V) or lever-operated separation (SB-4V)
- Wet or dry operation supported
- Best for applications requiring clean, efficient part-media separation
- Higher throughput for production environments
