RXX ceramic grinding media


RXX Ceramic Grinding Media

1. Extremely high cutting performance

2. Suitable for extra hardness metal like case hardened metal deburring and surface grinding

3. Suitable for vibratory finishing machinery and most other surface finishing machine

RXX ceramic grinding media is produced by mixing porcelain, kaolin,clay, river clay together with brown alumina oxide abrasives. The wet material is formed into desired shape (usually by extrusion and cutting) and then fired to vitrify. Fusion bonding is used to make some media. Such media are available in a wide range of shapes and sizes. Also, when the engineer selects the proper grade of abrasive, the correct proportion of abrasive to binder, and the most suitable binder, this media will adapt to a great variety of application, and workpieces.

The binder acts as a burnishing surface, and this works against rapid cutting.

In the manufacturing process, burrs are most certainly going to emerge on your metallic or plastic component. Burrs make the manufacturing process hard. Today the deburring process has become even harder.

However, today, in this article, you are going to get a clear definition and understanding of how to get the best finish on your components. In this article, you are going to understand:

  • What deburring is
  • How to use ceramic as a deburring agent
  • The benefits of using ceramic as a deburring media

Keep reading this article to understand the best.


Deburring – 4 Reasons Why You Shouldn’t Overlook Burrs

Now, you must be wondering to yourself what deburring is. But first, you have to understand what a burr is.

A burr is unwanted, raised edge(s) of a material, be it plastic or metallic that remains attached to that material after it has undergone machine modification, for example, through drilling, engraving, milling, grinding or even turning.

Here’s why you wouldn’t want burrs on your modified materials:

#1. Burrs make production costs to go up because they wear and tear machines, meaning you’ll either have to acquire a stronger tool or keep replacing parts where both are expensive at the end of the day.

#2. The finished product is not very appealing to the eye. Burrs make products look ugly because of their uneven, not to mention unwanted surfaces.

#3. Burrs put lives in danger because they may lead to miscalculation of dimensions during productions – meaning, faulty products are in the market for consumers to buy.

#4. Cut productivity by making parts harder to assemble because automation is not possible, thanks to these very burrs.

Now, deburring is the removal of the unwanted raised edges using a deburring tool, like for our case today, using ceramic material as a deburring media. Media, in the deburring world, is anything that is put to use to give that sleek final touch to a modified component.

Deburring has become a significantly expensive process. Why?

Nowadays, manufacturers are modifying their products because consumers prefer smaller products– smaller products mean more precision required to deburr them properly.


Deburring using Ceramic Media – Why use Ceramic over Other Deburring Media

First things first- There are different deburring media that are used during the deburring process. For instance, ceramic materials are used for deburring hard metals like titanium and steel.

Other abrasive media are plastic media, electrolyte deburring, water ice blasting, etc.

The good thing with ceramic media is that it can be used on soft metals too. Manufacturers recommend ceramic abrasives for aggressive removal of metal and general polishing. Ceramic abrasives can also be used for cutting heavy materials.

Using ceramic media for deburring is 30% more weight compared to using plastic abrasives. In essence, ceramic media is heavier than most abrasives.

Now, because of its toughness and density, ceramic media is the most preferred for the best finishes in hard metals. Its aggressiveness also counts in here.

You have to consider the following when dealing with ceramic media as your deburring agent:

Firstly, put into consideration the nature of the material you want to deburr. Ask yourself,

“Is it a hard metal? Or do I require heavy cutting?” Ceramic media, again, has an aggressive attribute suitable for this type of task.

If the material that is to be deburred is not so heavy, you may want to consider using softer deburring techniques, such as using plastic.ceramic deburring steel metal parts

Secondly, consider also the shape of the materials that are to be deburred. The ceramic media should be able to get into contact with all surfaces for exceptional output.

This ceramic media can be of different shapes, e.g., tetrahedron, cylindrical, triangular, etc. for the best surface contact with the material that is being deburred.

Thirdly, consider the size of the media. You surely don’t want ceramic media that is too big to reach all cavities of your component.

Also, you surely mustn’t need media that is too small; media that passes through cavities without deburring your material. It would be inconvenient for you financially.

Lastly, it would be best if you also put into consideration how aggressive your media should be. Ceramic media is quite aggressive, suitable for heavy metal finishing.

For softer metals, using ceramic material as a deburring agent may dent your metal because of its aggressiveness.

You must now be wondering why you should use ceramic deburring media over other forms of deburring material. Here are the reasons why you should.

Top 4 Benefits of using Ceramic Deburring Media

Ceramic deburring media has several benefits. However, you will learn the top 4 reasons why ceramic media is on top of its game.

Let’s dig right in:

#1. Ceramic media gives you control over how aggressive you’d want it to be. This means that it shortens processing times.

#2. Ceramic media is flexible enough in terms of sizes and shapes, which helps you a great deal during selecting how you’d want your material deburred.

#3. Ceramic media lasts for more extended periods because of its robust nature. Its hardy nature enables it to be cost-effective as you are not forced to keep acquiring this deburring media.

#4. Ceramic media gives your finish an outstanding look as it removes all machine marks, and cleans your metal until it shines. In short, it provides a sleeker look compared to plastic, which does not make deburred materials shine.

Ceramic deburring media can be used for:

  • Deburring heavy metals such as steel and titanium
  • Remove rust on iron
  • Rounding the edges of a hard metal such as titanium
  • Removes machine marks from an element.

In Conclusion

As you conclude, we’d like to know, was this article educative enough on ceramic deburring media?

Deburring has become tougher these days. Using ceramic media as a deburring agent can be very beneficial, considering you get the right shape, size, and aggressiveness for you to enjoy a wonderfully finished product.

Always, start by selecting your deburring method, followed by the proper deburring material’s size and shape. Follow the guidelines in this article, and you will have an outstanding finish!
