Gear Polishing FAQ Guide

1.  How is the performance of vibratory machines optimized for best gear polishing results?

The efficiency and performance of the vibratory polishing machine is important when it comes to achieving the best results for gear polishing.

Here is a list of method used to optimize the performance of the machines:


1.1 Amount of media used in the vibratory bowl

The usage of media is important when it comes to polishing gears.

The media helps the gears to achieve the best results and maintain its high quality. For this reason, it’s important to choose the right amount of media for polishing.

For general use, the media should always be two inches below the rim of the bowl. The failure to adhere to these standards for media usage will result in the damaging of your gear parts.

Keep in mind that using less media than required will also lead to unsatisfactory results.

1.2 Type of media

For all types of mass finishing processes, the shape, size, density, and abrasiveness of media is important for parts.

Regarding gear polishing, using an abrasive media is important in achieving optimal results for surfaces.

The less abrasive the media is, the lower the attrition rate and drainage process is. This further has great benefits when it comes to retaining the size and shape of media used. The more abrasive the media is, the quicker it loses its shape and size.



1.3 Usage of sound covers

Sound covers are the number one option for sound attenuation.

When it comes to dissipation of heat in the vibratory machine, the sound covers are crucial for inhibiting this when it’s taking place.

When sound covers are utilized, it’s important to increase the rate of liquid flow in order to replace any lost fluids caused by evaporation.


1.4 Motor speed and reduction of part impingement

During the polishing process, the vibratory finishing machines have bowls with ramped bottoms which acts to separate parts and media and unloading them after each cycle.

The chances of part impingement are high during the unloading process.

Vibratory bowl machines with motor inverters or speed settings provide the option to adjust the speed of the motor accordingly.

The maximum motor speed is usually 60Hz. However, during unloading it’s recommended to adjust the speed between 47Hz and 50Hz. This adjustment will help minimize the part impingement during unloading.



1.5 Drainage

A clogged drain can be detrimental to parts during polishing. This will cause liquid geysering on your gears.

This can further affect the efficiency of your vibratory tumbling machine during gear polishing.

In order to prevent this from taking place, we recommend removing all content from the bowl and cleaning all the holes before usage.

Another option is to replace all drain tubes with new ones to ensure that there are no blockages that can take place during operation. Ensure to place all your drain tubing close to the equipment as possible.
