Polar Vibratory Bowl — Batch & Internal Separation
The Polar FM-BB and FM-BIS series bowls feature a built-in separation screen and discharge gate that automatically sorts finished parts from media at cycle end — eliminating manual separation and enabling hands-off production cycles.
Key Features & Benefits
Integrated Separation Gate
- Built-in screen gate at bowl discharge
- Automatically separates parts from media at cycle end
- No manual sorting — reduces labour cost significantly
Wide Capacity Range
- FM-BB series: 1–2 cu ft for small-batch production
- FM-BIS series: 3–20 cu ft for high-volume runs
- Scale up without changing workflow
VFD-Ready (BIS Models)
- Variable frequency drive for amplitude control
- Precise tuning of media flow and finishing intensity
- Consistent results across long production runs
Automation Compatible
- PLC-compatible electrical architecture
- Timed cycle control and automated gate operation
- Integrates with compound dosing systems
Technical Specifications
The Polar Vibratory Bowl — Batch & Internal Separation series covers every production volume from single-batch bench use up to high-output 20 cubic foot continuous-run systems. FM-BB models are standard batch bowls for flexible batch processing; FM-BIS models add an integrated gate-and-trough separation system that automatically discharges finished parts without stopping the machine or manually handling media.
Key Features
- Solid urethane bowl — compatible with plastic, ceramic, and steel burnishing media
- Adjustable amplitude for precise control over part agitation and finish quality
- FM-BIS: internal separation gate discharges parts to a collection bin while media recirculates
- FM-BIS-03 includes Variable Speed Drive (VFD) as standard
- Accepts full PLC automation and compound dosing add-ons
- Heavy-gauge steel frame with corrosion-resistant finish

Applications & Finishing Examples
Production Batch Deburring
Automated timed-cycle finishing with hands-off parts discharge. Run batch after batch with consistent edge quality and zero manual sorting.
Burnishing & Brightening
Steel media burnishing for a bright, work-hardened surface finish on steel, brass, and copper parts — with automatic separation at cycle end.
Pre-Coating Surface Prep
Consistent surface texture on production parts before powder coat, anodize, or electroplating. Uniform results improve coating adhesion and coverage.
Plastic, ceramic, and steel media matched to your parts and required surface finish. Compound dosing systems and replacement items also available.

Polar FM-BB & FM-BIS Vibratory Bowls — Automated Batch Finishing with Separation
The Polar FM-BB and FM-BIS vibratory bowls combine the efficient circular media flow of a standard vibratory bowl with an integrated separation system that automatically separates finished parts from media at the end of each cycle. This is a critical capability for production environments where manual separation creates bottlenecks.
The FM-BB (Batch Barrel) series offers a straightforward separation gate in 1 and 2 cubic foot capacities, suited for general production use. The FM-BIS (Batch Internal Separation) series adds internal separation geometry and VFD integration for higher-throughput applications, ranging from 3 to 20 cubic feet.
All models are available to order through Machinist's Vault for Canadian shops. Request a quote to configure your model, capacity, media type, and automation options.
Frequently Asked Questions
FM-BB (Batch Barrel) models include a standard separation gate for general-purpose batch finishing, available in 1 and 2 cubic foot capacities. FM-BIS (Batch Internal Separation) models feature more advanced internal separation geometry and VFD integration for higher-volume applications from 3 to 20 cubic feet.
Yes. The FM-BB and FM-BIS bowls are compatible with steel pin and ball media for burnishing operations. Contact us to confirm media type, compound chemistry, and cycle parameters for your specific burnishing application.
Yes. FM-BIS models support automated gate control via PLC integration, allowing fully hands-off operation with timed open and close of the separation gate. Integration specifications are provided with the machine documentation and available on request during the quotation process.
The FM-BB series runs on 110 or 230V single-phase. FM-BIS models are available in single-phase (220V) or three-phase (220/440V) configurations depending on capacity. Confirm your available electrical service when requesting a quote.
The general rule is that your loaded media-and-parts volume should be approximately 75% of the bowl capacity. We size machines based on your parts per hour target, individual part size, and desired cycle time. Contact our team with those details and we'll recommend the right model.
