The VB(A) is a round-bowl vibratory polishing machine optimised for ball burnishing and high-luster surface polishing — the curved bowl geometry is the structural reason it outperforms flat-wall machines on these specific applications. The three design elements below explain why.
The VB(A) uses a round-wall bowl design that generates true toroidal (3D spiral) media movement throughout the full bowl volume. This continuous rolling and tumbling action maintains uniform media-to-part contact on all part surfaces simultaneously — a key requirement for ball burnishing with stainless steel or porcelain media. Flat-wall bowl machines produce a less consistent flow pattern that leaves zones of lower media activity, which shows up as uneven brightness on burnished parts. The round bowl eliminates these zones and is the reason VB(A) is the standard machine choice for mirror polishing applications.
The bowl is lined with hot-poured polyurethane from Dow Chemicals (USA) raw material, cast by automatic machine and cured at controlled temperature for 24 hours — producing 90 Shore D hardness lining that resists abrasive media wear significantly better than cold-cast alternatives. The vibration motor is from Shanghai Vibration Co., a dedicated vibration motor manufacturer. Unlike converted standard industrial motors, this motor is rated for continuous eccentric-weight loading and, with monthly bearing lubrication, maintains reliable performance for five or more years. Both components are sourced and built to the same standard across the full VB(A) model range from 30 L to 1200 L.
The VB(A) series runs from VB(A)30 (31 L, 0.5 kW) to VB(A)1200 (1200 L, 11–15 kW) across nine bowl sizes. All nine models share the same round-bowl geometry, the same PU lining material and the same motor brand — process parameters developed on a smaller model transfer directly when scaling up to larger production volumes. Optimal operating load is 70–80% of bowl volume (parts and media combined). The machine accepts all standard vibratory finishing accessories: acoustic noise lid (95 dB → 70 dB), Bosch Rexroth VFD, pneumatic separation gate and ProMinent dosing pump.
The VB(A) is the round-bowl model in the Inovatec vibratory finishing range, and the specific design choice for ball burnishing and mirror polishing applications. The round bowl wall generates toroidal media flow — a 3D spiral motion that keeps media in continuous contact with all part surfaces. This flow pattern is what makes ball burnishing effective in the VB(A): stainless steel shot, pins or porcelain media rolls continuously against parts, compressing surface micro-peaks to produce bright, high-luster results with very low material removal (< 0.02% on stainless steel). Choose VB(A) when your process goal is surface brightness, burnishing or mirror polishing. Choose VBS(A) when your process includes a separation sieve and automated discharge. Choose VB(B) or VBS(B) when parts are large, heavy or require a straight-wall working geometry.
The Inovatec round container vibratory polishing machines VB (A) series is suitable for processing workpieces in batches. The custom-made round machine chamber offers excellent Toroidal movement.
The round wall container design rotates the tumbling media, causing it to rub against the workpieces. Thus, it can offer intensive surface polishing. That’s why VB (A) series vibratory polishing machine provides excellent performance in ball burnishing and mirror polishing applications.
Hot-poured PU and a heavy-duty vibration motor are the primary components in our high-performance vibratory polishing machines. We make our polyurethane using raw materials sourced from Dow Chemicals, USA. We use an automatic casting machine to solidify the PU, then cure it at a controlled temperature for 24 hours. We use heavy-duty motor from Shanghai Vibration Co. With proper maintenance, it can last more than five years.

The VB(A) and VBS(A) are both curved-bowl spiral designs optimised for ball burnishing and high-luster polishing. The difference is the discharge system: VBS(A) has an integrated separation sieve for automated parts-and-media separation; VB(A) uses manual discharge. Choose VBS(A) for production lines where automated separation reduces labour. Choose VB(A) where manual separation is acceptable and lower initial cost is preferred.
The VB(B) and VBS(B) are straight-wall bowl designs suited for larger, heavier parts (gear housings, shafts, large castings) where the flat-bottom working geometry is needed. VBS(B) includes an integrated separation sieve with pneumatic shutter; VB(B) uses manual discharge.
Bowl size selection: start with your daily batch volume in kg and your largest part dimension. Operate the machine at 70–80% of total bowl volume (parts + media combined). If you process 50 kg per batch, a 200 L bowl is a reasonable starting point (media fills most of the volume; parts are typically 10–20% of total load by volume). Share your part dimensions, material and daily volume and we will confirm the right model and size.
Estimate daily part volume, working hours, and part size. Operate the machine at max 80% load for optimal performance.
We use top brands: Siemens Touch Screen, Bosch Rexroth Speed Converter, NSK bearings, Dow Chemicals PU lining, Mitsubishi PLC, etc., ensuring easy global sourcing and long-term reliability.
