Gear Polishing and Superfinishing Machines
Inovatec reviews equipment and media for polishing suitable gear surfaces. Define the starting surface and the required finish separately from burr removal. Tooth profile, lead, edge condition, bore dimensions, heat treatment, and the permitted stock removal must be included in the process review.
Vibratory systems can be evaluated for gear smoothing and burnishing with a suitable process. Review load, media circulation, liquid management, separation, and dimensional control.
Centrifugal barrel systems process suitable gears and media in rotating barrels. Confirm the usable envelope, load, part contact, process intensity, and surface result for the proposed model.
A centrifugal disc finisher uses a rotating bottom disc in a stationary container. Check the working gap, permitted part and media dimensions, loading, separation, and tooth protection.
Drag finishing moves individually fixtured gears through media. Assess fixture design, spacing, motion, accessible surfaces, and the required edge and surface condition.
Gear Polishing Applications
For automotive gears, specify the incoming surface, heat treatment, roughness target, and drawing tolerances. Verify tooth and bore geometry after the trial.
For bicycle gears and sprockets, assess the required appearance or functional surface and preserve tooth geometry. Compare media contact and separation for the actual part.
Engine gears need a controlled surface-finishing process matched to their profile and treatment. Evaluate the result against the component specification rather than assuming a polished surface eliminates power loss.
For reduction gears, provide the material, tooth geometry, mass, surface target, and inspection requirements. Select the machine around these requirements and production handling.
For tractor gears, assess load capacity, tooth spaces, media movement, cleaning, and handling. Confirm the selected process on representative parts.
Watch gears need a dedicated precision trial. Evaluate part retention, media size, tooth contact, accessible surfaces, and the dimensional changes allowed by the drawing.
Gear Polishing Media
Plastic abrasive grades can be assessed for smoothing and porcelain grades for suitable burnishing. A specified superfinishing process requires its own media, chemistry, and surface-control review. Check media grade, geometry, wear, lodging, and final cleaning.

- Share drawings or representative samples and identify the material and starting surface.
- Specify the target finish, critical features, and permissible dimensional changes.
- Include required output, handling, utilities, and delivery requirements.
- Review the proposed machine, media, cleaning, and sample acceptance criteria.
- Factory
- Before & After
Send the gear drawing, material and treatment, incoming surface, target finish, stock-removal allowance, quantity, and required output. Compare the proposed equipment with representative trial results.
Send your component and production requirements, available utilities, delivery destination, and required automation. Confirm the supplied configuration, accessories, trial scope, and delivery terms in the quotation.
Evaluate plastic or porcelain grades for the specific smoothing or burnishing stage. Superfinishing needs a defined process specification; media shape alone does not establish the resulting texture.
The minimum order is one machine. Standard payment terms are a 30% advance payment and the balance before shipment. Confirm the agreed terms and inspection arrangements in your quotation. Factory inspection can be arranged by agreement.
Confirm voltage, frequency, phase, current, and earthing for the selected machine. Discuss the 230 V, three-phase configuration referenced for this application and verify it against the supplied documentation.
Gear Polishing and Superfinishing: Process and Equipment Selection

Control Loading and Operating Conditions
Set fill level, media-to-part loading, liquid flow, drive settings, and unloading conditions according to the selected machine and accepted process. Review covers, temperature, drainage, separation, and contact during unloading. Use model-specific instructions rather than universal frequency or fill-level rules.
Select Media for the Required Surface
Plastic abrasive grades, porcelain, and high-density media have different roles. Agree on cutting or burnishing action, media geometry, chemistry, permitted material removal, and the required surface measurement. Check lodging and final cleaning.
Measure the Finishing Objective
Specify the starting and target texture, permitted stock removal, and tooth geometry. Potential changes to friction, noise, wear, or efficiency require relevant component or system testing; brightness alone does not demonstrate these outcomes.
Match the Process to the Gear Family
Review automotive, bicycle, engine, reduction, tractor, and watch components by their actual material, treatment, geometry, and production needs. Use separate trials where critical features or loads differ.
Separate Polishing from Burr Removal
Deburring removes specified burrs and controls edge condition. Polishing or smoothing addresses a defined surface texture. Agree on the process sequence and inspect tooth profiles, bores, edges, and dimensions after each required stage.
Define a Microfinishing or Superfinishing Stage
A controlled fine-finishing stage must have its own surface target, media and chemistry specification, stock-removal limits, and inspection method. Coordinate it with heat treatment and the other manufacturing stages required by the gear drawing.
Compare Equipment Configurations
Vibratory systems circulate a load; centrifugal barrel systems use rotating barrels; disc systems use a rotating bottom disc in a stationary container; drag systems move fixtured parts through media. Compare the envelope, load, contact, handling, separation, and trial result for the selected model.
Review Isotropic Finishing as a Defined Process
Isotropic finishing targets a specified non-directional surface texture. Chemically accelerated processes require compatible chemistry and suitable media, with dimensional and cleaning controls. Confirm the supplied process, documentation, and trial scope; do not assume that a generic polisher provides a proprietary process or its validated performance.
