Gears are the driving force of any machine. Anyone who has the slightest idea about how a machine works knows the importance of gears. Especially in automobiles, gears are the connecting elements between other components.
To polish automotive gears, you can go with any of the vibratory or centrifugal solutions from Inovatec. Gears are small parts so they suit all machines.
Bicycles use the fundamental principle of gear ratios to work. Bicycles have one large gear in the front and one or more in the rear. These gears have to be polished properly before installation.
If you’re looking for a cost-effective solution, you can stick to the vibratory finishing machines from Inovatec. But if you have the budget and work in high volume, we suggest investing in a centrifugal or drag finishing machine.
Engines have a lot of gears connecting different parts. The power is distributed with help from the gears. It’s a requirement to polish the gears to eliminate any power loss.
Engine gears usually come in different sizes. You can use a centrifugal disc finishing machine for faster results.
If you’ve seen the inside of a gear shaft, you’ll notice gears of different sizes. All of them don’t rotate at the same speed. Some of them rotate faster while some of them rotate slower. The slow ones are called reduction gear.
Reduction gear polishing is similar to other gear polishing. Go with a vibratory or centrifugal finisher.
Tractors are an integral part of agriculture. The tractors utilize a lot of gears to work efficiently. The gears have to be polished as well. Usually, tractor gears are larger in size.
It’s best that you stick with a vibratory bowl solution for perfect results.
There are not many jobs as fine as polishing watch gears. Watch gears are very precise. They have to show the accurate time. So, there is a need for high accuracy in polishing these gears as well.
The drag finishing machine is the perfect choice for watch gear polishing. We don’t recommend using regular vibratory finishers as you have the risk of damaging gears.

1. How Do You Optimize Vibratory Performance During Gear Polishing?
Improving the efficiency of vibratory machines in the gear polishing process is key and essential to achieving a satisfactory work-piece finishing. Here are some of the techniques to look into:
1.1 Media Volume in Vibratory Bowl
In the vibratory gear polishing process, the use of tumbling media is essential.
It helps to achieve and maintain a consistent and quality surface finishing on gears.
It is, therefore, essential to take cognizance of the volume of media in the vibratory bowl before initiating a cycle.
As a general rule, media volume in a vibratory bowl must always be two (2) inches below the outer diameter of the bowl’s rim.
At no point should your vibratory finishing machine run with a media mass that is below standard specifications.
Fewer media may result in process inefficiencies.
1.2 Choice of Vibratory Media
The choice of media (as per size, shape, abrasiveness, density, etc.) is an important factor for any mass finishing operation.
In this case, the abrasiveness of the media is a key ingredient in optimizing the performance of your vibratory machine.
In general, not so abrasive media is advisable; while for isotropic finishing, the choice of media has to be non-abrasive and of high density.
The lesser abrasive the media, the lower the degraded media deposits obtained at drains, and the lower the attrition rate of the media.
In other words, a less abrasive media retains its shape and size for much longer than a more abrasive media.
The form retention factor of the media becomes advantageous in applications where contact is essential for specific locations on the gear part.
1.3 Utilization of Sound Covers
When sound reduction is desired, sound covers are the best option.
It is imperative to note that sound covers inhibit the dissipation of heat when in place.
When covers are used, it is essential to increase the flow rate of liquid into the process to replace fluid loss by evaporation.
1.4 Regulate Motor Speed, Reduce Impingement
During a processing cycle, vibratory finishers with ramped-bottom bowls separate parts and unload them at the end of each cycle.
However, during the unloading phase, the chances of part-on-part contact are high.
Vibratory bowls with a motor inverter or speed potentiometer offer the option to tweak the motor speed.
Maximum allowable motor speed is often rated 60Hz, but during the unloading phase, it’s more advantageous to reduce the speed to 47-50 Hertz.
This action will help minimize part-on-part contact and the likelihood of parts going across media separation decks.
1.5 Ascertain the Integrity of Drains
Compromised drainage and a clogged and wrongly positioned drain tubing can cause liquid leaking around your equipment.
Liquid leaking can compromise the efficiency of your vibratory finishing machine during the gear polishing process.
To ensure the integrity of your machine’s drainage system, take away the content of its vibratory bowl, and cover all holes clean.
To achieve a better fluid drainage mechanism, you could also replace the drain tubing with new ones if needed.
The design of a drain tubing will require that it flows under gravity through its entire span to a sump.
If you observe deviations, ensure to put the tubing configuration in order.
Likewise, long stretch tubing is not uncommon but it’s advisable to make the drains as close to the equipment as practicable.
2. Which Media Is Suitable for the Gear Polishing Process?
In General, we recommend the use of plastic or porcelain media for several types of metal polishing.
More specifically, either plastic or porcelain media is suitable for the gear polishing process.
3. What Are the Benefits of Gear Polishing?

4. What Type Of Gear Can Undergo Polishing?
4.1 Bicycle Gear
Bicycles have both front and rear gears, and their functionality depends on the principle of work-to-gear ratio.
Hence, bicycle gears have to be adequately polished using a vibratory, centrifugal, or drag finisher from Inovatec, as the case may be, before installation.
4.2 Watch Gear
Watches have to tell time accurately, hence, there’s a need for a precise and high accuracy gear polishing process.
In this case, a drag finisher does the best job and does not inflict any sort of damage on the gears.
4.3 Reduction Gears
Reduction gears can be found inside gear shafts, and they are known to rotate more slowly than other gears.
To achieve adequate polishing, a centrifugal or vibratory finishing machine may be used.
4.4 Tractor Gear
Tractors are essential to agricultural activities, and they utilize numerous gears to function effectively and efficiently.
Generally, tractor gears are always massive, and they also require polishing using vibratory finishing equipment.
4.5 Automotive Gear
In automobiles, gears serve as the connecting element for several components.
Automotive gears can be polished with either a centrifugal or vibratory finishing machine from Inovatec.
4.6 Engine Gear
Generally, engines have numerous gears (in different sizes) connecting several parts, and likewise, helping with power distribution.
To ensure that there are no power losses, engine gears can be polished with a Centrifugal Disc Finisher.
5. What Is Gear Polishing?
Gear polishing gets rid of jagged edges of gears to enhance corrosion resistance, improve surface appearance, and reduce wear and fatigue failures.
Gears are sophisticated components with carefully engineered profile tolerances and micro-geometries.
Too much polishing can cause problems, hence, polishing of gears has to be done appropriately.
6. How Is Gear Micro Polishing Achieved?
Gear micro polishing is largely considered as the best thing that can happen to gears.
To achieve micro polishing, gears are subjected to a gentle polishing process that uniformly eliminates stress concentrations.
Micro polishing ensures less friction, lower heat generation, and improved fuel economy by polishing areas where gears contact other parts.
Some benefits of gear micro polishing include:
- Reduced contact fatigue and less wear
- Increased efficiency and power output
- Improved power density
- Improved resistance to bending fatigue
- Reduced maintenance and lubrication
