RF ceramic polishing media

RP Ceramic Polishing Media

  • 1. High Wear Resistance Performance
  • 2. High gloss polishing performance in short time with slightly cutting performance
  • 3. Wide application for metal components

RF porcelain media is ceramic media with specific gravity 2.40, while have no included abrasive inside the recipe, can develop excellent surface finishes amd produce tiny wearing. Because it is non-abrasive it brightens the surface of most metals. Work hardening materials may not brighten like non-work hardening alloys. While porcelain is an ingredient in some of the cutting media, manufacturer’s literature may distinguish porcelain from cutting media.

The Basics of Ceramic Polishing Media

Looking to try out ceramic polishing media for your needs? You can choose from a range of tumbling media for stones, metals, and other materials. In this post, we will explore ceramic polishing media – what it is, types of ceramic media, and how to use it. We will talk about the composition and the different types. We will also talk about how you can use ceramic polishing media the right way.

About Ceramic Tumbling Media

Ceramic polishing media is one of the most common types of finishing media. It accounts for almost 80% to 90% of finishing media along with plastic media. Ceramic polishing media can be used to impart different finishes on stones, metals, plastics, and other ceramic materials. It is especially useful for polishing steel, titanium, stainless steel, and other hard metals. Ceramic polishing media is sturdy and durable and can last longer compared to other media like plastic.

Composition

Ceramic polishing media generally has a relatively higher density than other media. You can find more than twelve types of ceramic compositions from different manufacturers. Each composition is used for a specific application.

Most ceramic media is kiln-fired ceramic and scores 7+ on the Mohs scale that defines hardness. Ceramic media may also contain porcelain sourced from pure aluminum oxide. Porcelain is great for finer grinding and achieving a high gloss finish. As you will find out, you can have different types of ceramic polishing media based on composition and use of abrasives.

Types of Ceramic Polishing Media

You can get two types of ceramic polishing media –

  • Ceramic media with abrasives
  • Ceramic media without abrasives

Ceramic polishing media with abrasives are used for finishing. Common abrasives used in ceramic media include silicon, silica, aluminum oxide, carbide, and zirconium.

To deflash or debur softer metals, sometimes sand or silica is also used. Aluminum oxide and silicon carbide are useful for comprehensive grinding in case of harder metals. Zirconium is often used to add weight to ceramic media and ideal for finely grinding various types of metals.

You will need to choose a type of ceramic polishing media based on your needs. Choosing an abrasive ceramic media may result in scratches in tumbling items. In that case, you can go for a smooth ceramic polishing media. Many manufacturers sell smooth ceramic polishing media that can be used to polish stones without compromising their appearance.

On the other hand, if you need to remove rust, abrasive ceramic media would be a good choice. Many other applications also need aggressive finishing and can use ceramic polishing media with abrasives.

You can also get ceramic polishing media in different shapes and material grades. Common shapes include cylinders, pyramids, ellipses, spheres, and so on. You can also choose the size of the particles according to your requirements.

The Perks of Ceramic Polishing Media

Ceramic polishing media has a number of advantages over other media. For starters, it has excellent tenacity and is highly durable. Ceramic media is also reusable and easy to clean. You can use the same media for multiple batches of tumbling.

Ceramic media can also improve the results of your tumbling. It provides optimum cushioning to the tumbling item to absorb impact. They can also be used as a filler and balancing the size of particles.

There is only one drawback with ceramic media. It can chip and lodge in machine parts.

Now let’s see how ceramic polishing media works its magic on different components within weeks of tumbling.

How to Use Ceramic Polishing Media?

To make optimal use of ceramic tumbling media and what it does, you must know how to use it. All you must do is follow these simple steps:

  • Empty a batch of stones into a barrel.
  • Add ceramic polishing media of different sizes to create a mix.
  • Tumble the mixture continuously.
  • Keep checking the shine and smoothness of the stones.
  • Stop tumbling when the gems reach the desired finish.
  • Separate the gems and ceramic polishing media.

If you’re concerned about how time-consuming the separation process will be, don’t worry. You can successfully separate the stones from ceramic media using a classifier and bucket. But make sure when you pour the mixture into the classifier it is dry. A good idea is to empty the barrel on a dry towel and soak off excess water from the stones.

Using this method allows you to separate ceramic media from the gems or metals hassle-free and in no time.

However, ceramic polishing media is also recommended for all metal types for polishing.

Selecting the Right Ceramic Polishing Media

When small media is needed to polish the stones, ceramic media offers a variety of options. The amount of abrasive used before firing the media determines how “aggressive” it will be. A higher density indicates that the process will be quicker yet the finish will not be as smooth. Such media will also wear out faster than ceramic polishing media incorporated with lesser abrasives. To choose the correct option simply answer these questions:

  • What shape and size do you require?
  • What proportion of small and big ceramic media should be used?
  • Do you need larger media to accelerate the process?
  • How difficult will it be to separate the media from the stones?
  • Will the media need replacement more often or is it durable?

If any of these questions get a negative answer, think again. The size or shape of ceramic polishing media you were considering will not be ideal with the stones you wish to polish. It’s one thing that you need to know when it comes to media polishing and replacement.
