5. What are the common categories of manufactured finishing media?

A wide selection of manufactured finishing media is available and serves different application purposes. Currently there are five categories of finishing media in the market.

Here is a list of the five manufactured finishing media:


  • Ceramic Finishing Media that has been Pre-Formed

This type of media is constructed using a variety of clay materials mixed through water and abrasive materials that forms its shape. Once shaped, they undergo a drying process and are heated at a high temperature. The amount of materials used, temperature, and amount of abrasive materials used in creating the shape of the media will cause them to differ.

The various shapes and sizes of this media makes it popular compared to other media that don’t have a variety of shapes and sizes.

Furthermore, there are three preformed ceramic finishing media types available including porcelain, light cutting media, and fast cutting media.



Porcelain media is non-abrasive that produces smooth and shiny surfaces on parts at a low cutting rate and is suitable for minimal deburring.

Light cutting media is ideal for fast turnaround times. They are suitable for deburring of die-cast and steel parts. The durability of light cutting media is longer, meaning that they last longer and can endure more than other media.

Fast cutting media is available in a wide selection. This media is ideal for large quantities of parts.


  • Preformed Resin-bonded or Plastic Finishing Media

Plastic or resin-bonded media has a great selection of abrasives, with quartz being the most common. They are available in different shapes such as pyramids, stars, triangles, cones, and many more.

This media is commonly used in cutting steel before it undergoes the finishing process.



  • Steel Finishing Media

Similar to other types of media, steel finishing media is available in a variety of shapes and sizes. The most common shapes that are used include flattened spots, ball shapes, oval balls, and steel pins. Each cubic foot weighs approximately 300 pounds. Among all types of media, this one comes at a higher price compared to others.



  • Dry Processing Media

Dry media is suitable for removing all moisture of parts. The common type of media is made of crushed corncob.

In addition, there are other types of media such as walnut shells and wooden pegs that is used to brighten the surface of parts.

This is an essential process for mass finishing, especially for parts that are not permitted to be exposed to moisture.



  • Alternatives

There are alternative media types that aren’t commonly used during the mass finishing processes like leather, shoe pegs, carpet tacks, and many more. However, they continue to serve their purposes in different application processes.


6. What is the process of finishing media?

Media is placed inside the tumbling machine of your choice. The media then become moved by the energy generated from the tumbling motor.

The energy that was generated from the tumbling media then transfers over to the parts in the tumbling machine.

Thereafter, the media and the parts rub against each other; it causes the surfaces of the parts to achieve the desired finish.



7.    What factors play a role in purchasing the correct finishing media?

There are various factors that play a role in choosing the correct media as it will ultimately have an impact on the product outcomes.

Here is a list of factors to consider:


  • Cut rate

This will determine the speed at which the surfaces of parts are finished. It finishes media using a high cutting rate that finishes parts faster with a lower quality result. However, media with a low cutting rate will cut parts slower that will result in desired outcomes.


  • Wear-and-tear

This factor will determine the lifespan of finishing media. The amount of abrasive material used to make certain media has an influence on the lifespan of the media. Media that cuts faster than others can endure more wear-and-tear compared to low cutting media.


  • Media hardness

There are different types of media made for various parts. The harder the part is, the harder the media should be. The softer the parts are, the softer the media should be. If hard media is used on soft parts, it will cause damage on the surfaces of parts.


  • Compound sensitivity

Choosing the correct compound for the media is important, as it will influence the cutting rate and the outcome of the surfaces of parts.


  • Fracture and chip sensitivity

During certain finishing processes, various media are mixed. This can have a negative effect on the outcome of product surfaces. If it’s not monitored properly, it will cause lodging issues on parts.


  • Size and shape

There are various sizes and shapes for finishing media used for different purposes. For this reason, it’s important to choose the right size and shape media for the type of outcome you want to achieve.

If you’re tumbling larger parts, then it’s best to choose large media. If your tumbling smaller parts, it’s advisable to tumble your parts using small finishing media to achieve best results.


  • Parts to media ratio

This is important when wanting to achieve desired outcomes of your parts. Choosing a media to parts ratio that’s appropriate for your application will successfully do the job. Depending on the outcome you want, you’ll have to adjust the ratio accordingly.


  • Flow rate and type of compound

Compounds used for deburring are suitable for cleaning parts and also does so in a fast time frame. Burnishing compound on the other hand is ideal for smoothening the surfaces on parts and increases the cutting rate of media.


  • Drainage rate and water flowing rate

Water helps in decreasing the level of friction between media and parts during tumbling. It also cleans parts thoroughly, leaving surfaces of parts cleaner and polished.


  • Machinery

The type of machine used for finishing media will determine the final product. Finishing media that has slower cutting speed produces better results if the correct media is used for the process.

The vibratory finishing machine operates at a higher speed with faster cutting speeds. Media are worn down faster than slower operating machines.

The rotary finishing machine has a slower cutting speed than the vibratory machine, allowing media to cut better and produce better results.


  • Surface contamination

If there are layers of contamination found on the surfaces of parts, then it makes it challenging for media to cut into and finish the inside layers of parts.

The amount of liquid substances including oils and surface grease contributes to the amount of contamination found of surfaces of parts.


  • Labor
