Ball Burnishing Machines for Metal Parts
Inovatec supplies ball burnishing machines for brightening and smoothing suitable metal components. The process uses dense, smooth media in a machine configured for its weight. Select the bowl or trough, loading arrangement, media, and compound together. For substantial burrs or deep machining marks, an abrasive preparation stage may be needed before burnishing.

A straight-wall vibratory bowl with a separation arrangement. Review chamber clearance, circulation, screen openings, and the permitted load when using steel burnishing media.
A curved-channel bowl with a separation feature for suitable batch finishing. Check part movement and discharge with the selected media and representative components.
A curved-wall vibratory machine for a specified burnishing process. Steel or other dense polishing media must be compatible with the machine, lining, compound, and workpiece.
A trough configuration for larger or longer workpieces, including suitable housings and exhaust components. Confirm loading space, dividers, handling, and the dense-media load rating.
Process Controls and Separation Options
A Prominent metering pump can dose water and compound for a compatible wet finishing system. Specify the required flow, chemical compatibility, and whether the process uses flow-through water or a recirculating supply.
A Bosch Rexroth variable frequency drive provides adjustable motor frequency on compatible equipment. Use only the settings approved for the machine and load; speed changes affect media movement and must be checked during process trials.
An acoustic cover can reduce operating noise. The result depends on the machine, load, enclosure, and workshop conditions. Confirm the cover design, access arrangements, and any interlocks for the quoted equipment.
A manual separation handle lets the operator initiate parts discharge on an equipped vibratory bowl. Select the screen opening from the actual part and media sizes, and check for retained media or lost parts during a separation trial.
A pneumatic separation gate can initiate a discharge sequence on compatible vibratory equipment. Confirm the compressed-air requirement, controls, screen design, and any downstream collection equipment included in the system.
Reverse separation is an option for applications in which the parts are smaller than the media. Suitability depends on the screen openings, part geometry, and worn media size. Test separation with production samples before selecting this arrangement.
Media for Ball Burnishing
Steel and stainless steel media are common choices for mass burnishing. Zirconia and porcelain options listed on this page require their own application review. Choose media size and geometry to contact the target surfaces without lodging in features. Use a compound suited to the metal and media, with the water flow and concentration specified for the process.

What does a mass finishing ball burnishing machine do?
The machine moves parts against smooth, dense burnishing media to improve the appearance and texture of suitable surfaces. This page concerns batch mass finishing with loose media. It is different from a single-point ball burnishing tool mounted on a machining center.
What makes up the complete burnishing system?
Review the machine and lining, dense-media load capacity, media, water and compound supply, drainage, separation, rinsing, and drying. These elements affect part movement, media condition, surface appearance, and the handling required after the finishing cycle.
Which media can be used?
Steel and stainless steel media are established mass burnishing options. The page also lists zirconia and porcelain alternatives for appropriate polishing applications. Review density, geometry, surface condition, chemical compatibility, and the machine rating rather than selecting media by name alone.
How does vibratory ball burnishing work?
Vibration produces movement of the parts and media in the bowl or trough. Contact with smooth media produces the burnishing action, while the liquid system supports the specified process. Drainage and separation depend on the equipment fitted to the machine.
What results should be specified?
Agree on surface appearance, measurable texture where required, cleanliness, dimensional limits, and protected features. Hardness, corrosion resistance, and roughness requirements need their own application-specific evidence and acceptance criteria. Inspect the trial parts against your specification.
Which machine configuration suits the parts?
Bowl and trough designs suit different geometries and handling needs. Review the longest dimension, total load, media density, access to the target surfaces, and part-on-part contact. Confirm whether screens, dividers, or controlled discharge are required.
How does this differ from roller burnishing?
Roller burnishing applies a controlled tool contact to a selected surface, typically during a machining operation. Batch ball burnishing uses loose media to contact accessible part surfaces. The processes require different equipment, loading, controls, and acceptance criteria.
Which materials and components should be tested?
The listing includes suitable steel, aluminum, brass, copper, and die-cast components. Test the actual alloy, heat treatment, plating or coating, and surface condition. Delicate edges, thin walls, and critical features can limit the acceptable load and finishing action.
Where is mass burnishing used?
Potential applications include stamped components, castings, fittings, and machined parts that require a brighter or smoother appearance. The application name does not establish suitability: provide the drawings, finish requirement, allowable contact, and downstream operation.
When is another finishing stage required?
Smooth burnishing media is not a substitute for abrasive cutting when substantial burrs, heavy scale, or deep tool marks must be removed. Evaluate preparation, burnishing, rinsing, and drying as separate stages where the incoming surface requires them.
What can go wrong during a trial?
Overloading, excessive contact, unsuitable chemistry, media lodging, or poor separation can damage parts or leave an unacceptable surface. Check new and worn media against holes and slots, and inspect both the visible surface and critical dimensions.
How should operating settings be selected?
Use the machine’s approved settings and a controlled trial. The page’s 900–1500 rpm reference concerns a listed motor adjustment range, not a universal process speed. The previous 10–20 minute cycle reference also requires verification for the actual part, load, and finish.
Which compound and water arrangement is suitable?
Select the compound for the workpiece alloy, media, surface target, and water conditions. Do not assume that every burnishing process needs acidic chemistry. Confirm concentration, flow, recirculation if applicable, corrosion control, rinsing, and process-water handling with the proposed formulation.
